Cliff hanger! Seriously it is really nice to see a company (rep) so interested in their equipment that they are ready to help fix a problem on a second hand motor. Thumbs up for Oceanvolt.
You guys are very considerate in your videos by detailing problems with solutions. You deserve a Grammy for such an outstanding show amongst all the sailing videos on You Tube. Bravo!!
I agree - not many companies would send over a rep. to check out a piece of equipment that has already had a pretty full life. It is nice to see a company standing behind its product.
I think it is more than just the bearings which have had the metal debris run through them. It sounds like the tick of a damaged tooth on the prop shaft.
@@daleguenther5826 Yep, as soon as I heard the noise outside the water. Knock speeds up with RPM. Damaged gear tooth all the way. Most likely cause: Loss of oil/ingress of water then a sudden shift from forward to reverse chipped a tooth.
I'm certainly not a mechanic, but my guess is that the bevel gears between the bottom of the shaft from the sail drive motor, and the horizontal shaft leading to the prop itself, is where the wearing is coming from that is producing metal shavings in the oil. Just a guess. Best to you guys. PS-been reading your story on Instagram, Kika, and I'm SO taken by your loving sensitivity and how you've turned your emotionally inhibiting past into a positive, so you can live a mentally healthy life. You guys are simply great. Love from an old man who used to sail and can't due to health. I live through you two. Sail on. Thank you.
Finding the problem is advantageous for the company as well because although 5 years (the whole thing is that old? or just the motor?) is a long time to use a bearing and it's going to need replacement now and then, it helps them understand where the failure points are and what they could work on to extend the life of their product improving their reputation.
it seems to me that the problem is in the bearings that hold the axles. if seawater has entered in the body of the bearing then it corrodes easily it's a relatively "cheap repair" it’s just complicated to take it all apart and reassemble it
Fathers day weekend and you pulled out the "Trick my Dad taught me". What a great Dad! His pride has to be off the charts watching you do all that you do!
It was cool to see someone else using the old trick to listen to mechanical noise. My grandpa taught me that in my teens. I have used it more than once to listen to the valve train on auto engines. Nice to see you also have someone there willing to work with you on your sail drive issue. Best of luck.
I must be honest. Although I regularly watch many youtube channels I rarely subscribe. But seeing your subscribers spot a problem, and seeing your patreon react to your rescue, I see that UmaNation is a real thing, a sort of partnership between you and your viewers. This is a very good thing. Also I would say that the two of you have kind of "wrote the book" on how to rescue/revive/perfect an old boat, and that is a sort of encyclopedia of "how-to". Add to that the stories of your sailings and adventures and okay: this old guy is signing up. I'ma gonna hit subscribe right now!
It may sound bad, but I love watching and hearing things go wrong, as long as they get it fixed, since it teaches me what to look for as symptoms. Thanks guys for sharing this
HELLO from Alabama! Has nothing to do with your video just started watching your channel and just wanted to say you two are absolutely extraordinary and wish you guys the best in life..... much love to you!!
Are'nt those kids two impressive ? Look at their frst videos, you'll be even more impressed. With what they started with to the condition of UMA now is awesome. Marc, a regular viewer and admirer from the start !!
So sorry guys. Nice to have a rep get ahold of you. Definitely shows their level of professionalism toward, not only their product, but those who use them.
I giggled when I saw your stethoscope at 19:23 - great tool! Using that trick to test the clacking engine on a used car, we determined the noise was not the rods as the owner feared. Long story short-ish, it actually was the result of an incorrect belt pulley system traveling front-to-back-to-front-to-back along a 1/16" slack space. Yup, a great tool made for a great deal!
I was one of those who remarked about the noise, and i am shore that when the problem is solved the efficiency figures will be better. I wish you both all the best, And i am astonished to see your endurance when things do not go you're way. Kudos
Being a Belgian, living in Australia, You guys are lucky to be in the Netherlands. These guys will help you out. They are water people and fine sailors.
Uma is a Pearson. Pearson has a reputation for overbuilding boats which means the boats are stronger than they have to be. An example: We sailed out of the Golden Gate into fifteen foot swells at twenty second intervals. It was rough going and we were not making any headway so we turned back and anchored in Clipper Cove. But the boat took it all in stride. A Hunter kept pace with us under the lee of the Marin headland, but as soon as she hit the open ocean, things went bad. She split her seams. The skipper called mayday and the Coast Guard rescued them, towed them back to Alameda while they ran every pump they had to keep her afloat. We talked with the insurance agent some days later. He told us the boat was a total loss.
I think UMA is a timeless classic. Rebuilt and reloved. I get cramp just thinking of the spaces Dan has been inside that shell. Kika's enthusiasm and grit is a great additional balance to make this pair just great. These episodes are just amazing IMO. 200K Subs too! Nice
Kind of crazy that Oceanvolt didn’t sponsor you before but they are helping now that their motor isn’t looking good. I bet the almost 200k subscribers helped their decision
Kika, you’re doing wonderful driving the boat. You’re comment about confidence struck me. You have great skill running Uma, you have to believe in yourself. You’ve crossed oceans, a dock is nothing. 👏 keep up the amazing work. Also kudos to oceanvolt for the support 👍 Keep up the awesome videos 🇨🇦
Kika, there’re 3 types of sailors in The Netherlands. Those who have ended up the wrong way around in a lock, those who will and those who lie about it. 😉
I (well, my parents) never have ended up wrong in a lock. Then again, they sold their boat while they were ahead and after only navigating a very few :)
Glad you found the problem on the Ijselmeer instead of the middle of the ocean. With a great bonus you are in the Netherlands, a nation proud of it's boat building history. And even now on the leading edge of design.
OH wow! I am now current with all your 'steps' I was trying to find 'step 223' without realizing I just finished the most recent video. The addiction is real.
Kudos to Oceanvolt to get so involved with an older motor! And, to have this happen in Europe where parts and experts are available is so good. You left us hanging; can’t wait until next week. Go Go Uma crew!😁💥
Thanks for the video. Nice to see the old country again. I left the Netherlands 62 years a go for Australia and visited Enkhuizen in 2001. That old mechanics trick works well on bearings and engine tappets, etc.
A few days ago I stumbled on your first video. Since then I bing watched your first 28 videos and then have watched others, for example, the one with the huge waves and the broken switch. I love what you guys are doing!
i really hope you guys plan on spending at least 30 years or more living on your boat !! You can dock easier than you realize and you for sure have the skills to do so , you just don't know it yet
Hey, certified millwright here. A knocking gear his a bad gear or missed aligned gears. Either way it’s done. Also install a drain plug with a magnetic head. It will help to keep any normal grinding out of your oil.
Yep, not much has changed just that a computer makes adjustments on the fly instead of a mechanic in a shop. Electric or combustion a motor is still a motor.
I still do it a lot, especially when trying to locate a grinding or some bearing noise. I also prefer a wood stick to metal as it's easier to listen to.
I was taught to use a hardwood dowel, but a socket extension works too. . Also learned how to use a phone book to adjust a car door or hood I guess that shows my age, but they still work. Glad to see Dan use the skills learned from his dad. You guys have come so far with this boat and your lives. Basically a scrap boat to a beautiful tech showcase. Keep sailing, keep learning. And thanks for bringing us along with you.
Very interesting episode. The oil leak is the culprit causing the wear on the gears. The support you have there is wonderful to see. Looking forward to part 2. Be well stay safe.
Yes I agree with all the supportive comments re the Electric Motor Mfg. Sailing Uma’s International audience is watching and the Company did the correct thing by investigating and demonstrating excellent Customer Service and Technical Support.
it only makes sence because if some where else a coustomer gets an similar noise they can, based on the information gained from Uma help the other coustomers faster. shortening Hauling out and yard storrage fees. Such a healthy relationship is what should be a given no matter the typ of industry.
I saw another video on UA-cam of a guy sailing in light winds and when tacking he just switched on his electric engine for a minute or so to help with the tack he absolutely loved his motor!
Love the idea of the regeneration of power under sail and what a great company still interested in their product 5yrs later. Good luck with the repair and hope it goes well. Also I still get nervous manoeuvring in tight spots as my yacht doesn't steer very well in reverse but I use the prop walk which is ok so long as there isn't much wind so I fully sympathize with you Kika
Thanks for another great episode! Really lucky the OceanVolt rep is an absolute champion to get in contact, and you decided to take the time for the pull out or who knows what issues may have been faced. Fantastic work as always, and I hope it's a relatively easy fix. I have been looking at OceanVolt recently, it's great to see they are following the sailing communities online. Take care!
That what I was thinking. I've done work on cars and other things and it sounds like when a bearing has gone out on a wheel or a shaft. A steady knock that increases with speed. If I were them and didn't know the past history of the drive, I would pull the drive and have all the bearings and seals in the skeg replaced. Replacing just the problem parts may solve the problem for now, but it could very well come back to haunt them later.
I would not "assume' anything is FINE, especially from watching a video. This needs to work, you can't just pull to side of the road and call a tow truck. The salt-water is trouble. Pull it completely apart, the gears have tolerances, you need to measure the gears to see if it is within specs, then replace ALL seals , races, and bearings. Do a complete re-work so you only do this once , since the boat is out of the water . Nice to see you have support for a used unit. Being UA-camrs pays off in many ways . Thumbs up guys EDIT: Also, if this ran in the last boat for time, the gears could be damaged from heat and the steal could be cracked, I have no idea what the set-up looks like but ruunning this with sea- water could stress everything made of steel. I have seen a differential ring gear develop stress cracks from a bit of fresh water mixed with gear oil.
@@gsh341 Yeah, looking at the material in the oil looks like bearing hardning, Might be shimming on the pinnion gears causing too much end float, Best is to replace the bearings anyway as with the introduction of water is bad, then check the mesh on the pinion. Good luck guys
And,,,, I would say they wasted a lot of gear oil flushing and testing. Only delayed the obvious, the unit has to be taken apart and rebuilt. If I were paying for the lift time, I wouldn't have wasted a day troubleshooting. Seawater told the story.
Your contact with Oceanvolt is good luck and good customer service. Great to see a company believing in their product. My guess is like many below so I will not bore you. My dad taught me the same trick to listen to mechanical sounds and it works. Waiting with anticipation for the next instalment and hope this problem can be resolved quickly and without a huge cost. Be well.
I can’t help but think back to when you were installing it and you said something to the effect of “ the beauty of a sail drive is in it’s simplicity “ and I wondered how anything could be simpler than a straight shaft with a prop on the end. It made sense once I saw the motor packaging and orientation what you were referring to but I doubt many people consider sail drives to be more simple than a shaft drive. Definitely not with a conventional auxiliary where the power has to negotiate two 90 degree angle changes. Looks like you are on the right track though. Good luck!
Hi Kika, when it comes to docking i have the same issues as you and i am sailing nearly my whole life. We have a motorsailor and docking this boat is like docking a bus. It is drifting like a bunch of straw. So i always handle the lines and let my father be the boss behind the rudder. Then i always argue that he is old and cannot move fast enough ;-). But i have to confess that he can dock it single handed... but he has nearly 70 years of experience. The fact is that i am mostly not selfconfident enough to play the leading role in the socalled "Hafenkino" (harbourcinema), but i am still working on it. But at least i know that i can dock the boat in a case of emergency. It wont look nice but it would be tied up! Cheers from the baltic sea!
So nice Oceanvolt is helping, your Re-Gen numbers are simply amazing, to get 150 to 250 Watt regain power at 6 to 7 knots without an engineered re-gen prop is simply fantastic, many with an electric drive dream to get those numbers. Now make sure the Oceanvolt region charge control is working so you do not exceed the Battery voltage, I am sure Oceanvolt uses a reliable region charge regulator, cheers to both of you !!
I'm sorry your Saildrive has metal dandruff/bearing/gear damage identified from your oil flushes and "socket stethoscope". Also a massive shout out to OceanVolt for stepping up, it speaks volumes for them being a class act. Fingers crossed that this doesn't mess with your timeline and a fix is cheap, Kika & Dan. Hugs, UK fan x
I am gutted for you that this problem has come up. But love the video. Your pain is our gain. This is GREAT content. Looking forward to the autopsy! :-)
Love these DYI videos. Obviously Dan's dad had a lot to do with his talent for it, I like the screwdriver as stethoscope trick. Nice to have friends! Oceanvolt is on the ball! Great to have this fellow there looking at a company product. When you are in a bind, no matter how independent you are, friends are critical. I love videos like this. Looks like you'll have to replace bearings. Looking forward to seeing the Saildrive pulled out. Grawet work Dan! Kika, great handling the boat in the lock. Thanks for posting. Muchos gracias, as they say in South Flin Flon.
Oh, a P.S. UA-cam had an evaluation thingy for your vid, above, with boxes to tick. I never saw that before for any video. Questions were: Did you like it? (Yes.) Why? Then a series of boxes, to tick, asking if the video was: Inspiring? Informative? Enjoyable? ect. Never saw that before. Of course I clicked all I liked about it and why. For some reason UA-cam is giving you some extra attention. FYI.
Kudos to Oceanvolt... I know they came out to see you for there product and for PR... And it worked lol will be my firstt choice.. Oh sorry second choice after a forklift motor lol
Sounds like a bad bearing. New bearing(s) and seals and you’ll be fine I’m sure. Great to see a company backing their product even if it’s out of warranty.
I think you are right. I guess there is a problem with a lower bearing of a vertical shaft which doesn't hold the shaft sturdy and probably there is no proper alignment of the gear installed on the vertical shaft relative to the gear on the horizontal shaft. And that could be a reason of a massive wearout of gears which ofcourse produces a lot of noise.
If the bearings died months ago, and they kept using the drive, both of the shafts could be very eroded where the bearings sit. I’ve fixed / remanufactured many an industrial conveyor shaft that was eroded to half its diameter where the bearing used to be before it simply broke, stopping production, and they are forced to make a repair. If it works don’t fix it isn’t the boating or the aircraft way, but you guys know that of course. Just had to tell my little story. Happy sailing you two.
It’s sounds to me like there’s a broken tooth off one of the gears. I’ve heard that before. That’s the rapping sound. And the bearings are toast. That’s scraping sound. Replace everything in the lower unit.
Kika , your editing is outstanding...definitely ready for National Geographic’s! Are you using remote mics? Dan’s engineering insights are wonderful for a pseudo geek like me.
Hmm. With shavings in the oil, seems kinda like you had a leak compromise the oil which caused one of the bearings to wear down. Looking forward to part 2
@@tiborkiss9186 - It all depends on how it was maintained and used by the previous owner. Some cars last a long time and some cars are piles of crap after just a few years and it's all due to maintenance and use. Sail drives and other things are no different.
Nice shots of the old fisherman’s town of Enkhuizen with the houses, bridges and bikes. Hope you are having a nice time there while reparing the problem with the prop.
My country is crammed with beautiful towns with lots of 16th and 17th century buildings. Of these Hoorn and Enkhuizen i.m.o. stand out as the best preserved. I hope you find the time to look around and enjoy. Kudos to Oceanvolt for their service, it will no doubt save you a lot of trouble when this problem is taken good care of.
Sounds like a flat spot: the reason they're likely not hearing it in forwards is its likely not rolling any more, just sliding: in reverse it's rolling so you hear that tick tick tick. (someone else mentioned gears climbing... Let's hope it's not that bad!) Maybe it's worn, maybe it took a light strike at some point (it happens). I have no experience with sail drives, but I've heard they're a nightmare, so I'm looking forward to the followup video.
To be continued.... I’m wondering did you load any software motor characteristics into the engines management system? Just like a car it could have insane acceleration, but that might rip it out of your boat.
Well....that sucks! But on a high note, you discovered this early, have experts on hand, and can repair it without having to ship parts half way around the world. So for a breakdown, this was probably the best time and place for it! Actually, it's not really a breakdown, it's catching a problem before a breakdown occurs. Which is always preferable. An old mechanic friend of mine has always said "learn to listen to your car (boat), she will tell you when something is wrong, well before something breaks". So now you know what your sail drive sounds like when it's sick, and afterwards when it's repaired, you'll know how it sounds when it's healthy. A valuable lesson to learn and remember. Cheers from Winnipeg.
Sounded like the gears in the sail drive when I heard it a few steps ago. Be interested to see what they come up with. Good for them for standing behind their product.
a great engine gear analysis I like that old engine trick Ive used it for many years and the new mecanics could never figure out how i did it Kudos to your dad Yes im 70 years old Happy fathers day s

First and foremost commandment for Tech-Companies in real sailing context: Thou shalt pamper Your multipliers.
@@asdfghjklqwertyuiopzxcvbnm2281 be sure of it!
- Absolutely agree... Set high standards, then live up to them.
They sent this to them I thought so we would buy one for ourselves. Tell me if I am mixing up my channels if I'm wrong. Still love these guys.
@@popsoldboats3406 no they bought the motor used
You guys are very considerate in your videos by detailing problems with solutions. You deserve a Grammy for such an outstanding show amongst all the sailing videos on You Tube. Bravo!!
Nice to have a company’s support in this inquiry and repair.
It’s great that the company is involved. It shows they care. 👍🇨🇦

I'm certainly not a mechanic, but my guess is that the bevel gears between the bottom of the shaft from the sail drive motor, and the horizontal shaft leading to the prop itself, is where the wearing is coming from that is producing metal shavings in the oil.

Finding the problem is advantageous for the company as well because although 5 years (the whole thing is that old? or just the motor?) is a long time to use a bearing and it's going to need replacement now and then, it helps them understand where the failure points are and what they could work on to extend the life of their product improving their reputation.
That was my guess as well. The tolerances there are tight. If a bearing is worn it will allow greater slop in the gear meshing.
More play in bearing= excessive gear lash and seal failure. Sounds pretty likely to me.
it seems to me that the problem is in the bearings that hold the axles.
if seawater has entered in the body of the bearing then it corrodes easily
it's a relatively "cheap repair"
it’s just complicated to take it all apart and reassemble it
Definitely the lower miter gear area, as that's also where the water would collect...
Fathers day weekend and you pulled out the "Trick my Dad taught me". What a great Dad! His pride has to be off the charts watching you do all that you do!

I (well, my parents) never have ended up wrong in a lock. Then again, they sold their boat while they were ahead and after only navigating a very few :)
there are more than seven types of sailors in the Nether lands lets take a close look at the indonesian language

and publicity ;)
Thanks for the video. Nice to see the old country again. I left the Netherlands 62 years a go for Australia and visited Enkhuizen in 2001. That old mechanics trick works well on bearings and engine tappets, etc.
I thought that motor was disappointingly loud. Glad you have found the culprit. Look forward to seeing what's inside. Love your channel.

i really hope you guys plan on spending at least 30 years or more living on your boat !! You can dock easier than you realize and you for sure have the skills to do so , you just don't know it yet
Hey, certified millwright here. A knocking gear his a bad gear or missed aligned gears. Either way it’s done.
Also install a drain plug with a magnetic head. It will help to keep any normal grinding out of your oil.
Haven't seen anyone listen to gears in forever. Well, since my mechanic about 30 yrs ago. Still valid, even with modern equipment.
Yep, not much has changed just that a computer makes adjustments on the fly instead of a mechanic in a shop. Electric or combustion a motor is still a motor.
I still do it a lot, especially when trying to locate a grinding or some bearing noise. I also prefer a wood stick to metal as it's easier to listen to.
Basic physics doesn't change because of more printed circuits, does it?
@no ididnt yup, broom handle or old grease stained dowel!
I was taught to use a hardwood dowel, but a socket extension works too. . Also learned how to use a phone book to adjust a car door or hood I guess that shows my age, but they still work. Glad to see Dan use the skills learned from his dad. You guys have come so far with this boat and your lives. Basically a scrap boat to a beautiful tech showcase. Keep sailing, keep learning. And thanks for bringing us along with you.
Thank you for the explanation on the regeneration of power. That makes sense and I didn't understand prior to this.
I'd definitely look at having this oceanvolt drive as a backup on a 50ft. The regen is pretty nice.

The boat looks awesome. Really shows your hard work and great team work is paying off.
Let's hope it's just a bearing you can replace and the gears are undamaged. Great service from Oceanvolt.
Love the idea of the regeneration of power under sail and what a great company still interested in their product 5yrs later. Good luck with the repair and hope it goes well. Also I still get nervous manoeuvring in tight spots as my yacht doesn't steer very well in reverse but I use the prop walk which is ok so long as there isn't much wind so I fully sympathize with you Kika
Good old school engineering tip to listen to the internals, works every time.
Thanks for another great episode! Really lucky the OceanVolt rep is an absolute champion to get in contact, and you decided to take the time for the pull out or who knows what issues may have been faced. Fantastic work as always, and I hope it's a relatively easy fix. I have been looking at OceanVolt recently, it's great to see they are following the sailing communities online. Take care!
My guess: main thrust bearing race is shot, oil's leaking from the shaft seal under prop vibration, and the gears are fine. :)
That what I was thinking. I've done work on cars and other things and it sounds like when a bearing has gone out on a wheel or a shaft. A steady knock that increases with speed. If I were them and didn't know the past history of the drive, I would pull the drive and have all the bearings and seals in the skeg replaced. Replacing just the problem parts may solve the problem for now, but it could very well come back to haunt them later.
Gordon Lamb that seems like a pretty good diagnosis.
I would not "assume' anything is FINE, especially from watching a video. This needs to work, you can't just pull to side of the road and call a tow truck. The salt-water is trouble. Pull it completely apart, the gears have tolerances, you need to measure the gears to see if it is within specs, then replace ALL seals , races, and bearings. Do a complete re-work so you only do this once , since the boat is out of the water . Nice to see you have support for a used unit. Being UA-camrs pays off in many ways . Thumbs up guys EDIT: Also, if this ran in the last boat for time, the gears could be damaged from heat and the steal could be cracked, I have no idea what the set-up looks like but ruunning this with sea- water could stress everything made of steel. I have seen a differential ring gear develop stress cracks from a bit of fresh water mixed with gear oil.
Yeah, I think I could live with that theory As an old fart who's rebuilt car gearboxes & engines for 50 years
@@gsh341 Yeah, looking at the material in the oil looks like bearing hardning, Might be shimming on the pinnion gears causing too much end float, Best is to replace the bearings anyway as with the introduction of water is bad, then check the mesh on the pinion.
Good luck guys
You did very well and you are still smiling. Thank you.
Once you have salt water in there your bearings are done don't even try replacing just one they're on borrowed time.
And,,,, I would say they wasted a lot of gear oil flushing and testing. Only delayed the obvious, the unit has to be taken apart and rebuilt. If I were paying for the lift time, I wouldn't have wasted a day troubleshooting. Seawater told the story.

Your contact with Oceanvolt is good luck and good customer service. Great to see a company believing in their product. My guess is like many below so I will not bore you. My dad taught me the same trick to listen to mechanical sounds and it works. Waiting with anticipation for the next instalment and hope this problem can be resolved quickly and without a huge cost. Be well.
Love the technical stuff - give us a update on the sail drive!!!
I can’t help but think back to when you were installing it and you said something to the effect of “ the beauty of a sail drive is in it’s simplicity “ and I wondered how anything could be simpler than a straight shaft with a prop on the end. It made sense once I saw the motor packaging and orientation what you were referring to but I doubt many people consider sail drives to be more simple than a shaft drive. Definitely not with a conventional auxiliary where the power has to negotiate two 90 degree angle changes. Looks like you are on the right track though. Good luck!
Hi Kika, when it comes to docking i have the same issues as you and i am sailing nearly my whole life. We have a motorsailor and docking this boat is like docking a bus. It is drifting like a bunch of straw. So i always handle the lines and let my father be the boss behind the rudder. Then i always argue that he is old and cannot move fast enough ;-). But i have to confess that he can dock it single handed... but he has nearly 70 years of experience. The fact is that i am mostly not selfconfident enough to play the leading role in the socalled "Hafenkino" (harbourcinema), but i am still working on it. But at least i know that i can dock the boat in a case of emergency. It wont look nice but it would be tied up! Cheers from the baltic sea!
Really nice to have a Rep. showing such an interest in their product..speaks volumes for their Comapany..👍👍👍🇺🇸
Very impressed with the Oceanvolt sail drive dealer. Cheers!
Sounds like you have got to the ‘bottom’ of it already.😉
So nice Oceanvolt is helping, your Re-Gen numbers are simply amazing, to get 150 to 250 Watt regain power at 6 to 7 knots without an engineered re-gen prop is simply fantastic, many with an electric drive dream to get those numbers. Now make sure the Oceanvolt region charge control is working so you do not exceed the Battery voltage, I am sure Oceanvolt uses a reliable region charge regulator, cheers to both of you !!
Almost two hundred thousand subscribers congratulations!
I'm sorry your Saildrive has metal dandruff/bearing/gear damage identified from your oil flushes and "socket stethoscope". Also a massive shout out to OceanVolt for stepping up, it speaks volumes for them being a class act. Fingers crossed that this doesn't mess with your timeline and a fix is cheap, Kika & Dan. Hugs, UK fan x
I am gutted for you that this problem has come up. But love the video. Your pain is our gain. This is GREAT content. Looking forward to the autopsy! :-)
Might be just a little bearing and seal surgery, not an autopsy yet, hopefully ...
Best sailing vlog on the Tube. Good luck and happy sailing. Cheers
You're champs, thanks for sharing all that info!
Love these DYI videos. Obviously Dan's dad had a lot to do with his talent for it, I like the screwdriver as stethoscope trick. Nice to have friends! Oceanvolt is on the ball! Great to have this fellow there looking at a company product. When you are in a bind, no matter how independent you are, friends are critical. I love videos like this. Looks like you'll have to replace bearings. Looking forward to seeing the Saildrive pulled out. Grawet work Dan! Kika, great handling the boat in the lock. Thanks for posting. Muchos gracias, as they say in South Flin Flon.
Oh, a P.S. UA-cam had an evaluation thingy for your vid, above, with boxes to tick. I never saw that before for any video. Questions were: Did you like it? (Yes.) Why? Then a series of boxes, to tick, asking if the video was: Inspiring? Informative? Enjoyable? ect. Never saw that before. Of course I clicked all I liked about it and why. For some reason UA-cam is giving you some extra attention. FYI.
Sometimes I really envy you guys. This is NOT one of those times. ;)
Thanks!
Kudos to Oceanvolt...
I know they came out to see you for there product and for PR...
And it worked lol
will be my firstt choice..
Oh sorry second choice after a forklift motor lol
It’s great that a rep from ocean volt got in touch and diagnosed your motor. They stand by their product. Good luck
Sounds like a bad bearing. New bearing(s) and seals and you’ll be fine I’m sure.
Great to see a company backing their product even if it’s out of warranty.
You mean a missing teeth that is grindend down now xD?
I think you are right. I guess there is a problem with a lower bearing of a vertical shaft which doesn't hold the shaft sturdy and probably there is no proper alignment of the gear installed on the vertical shaft relative to the gear on the horizontal shaft. And that could be a reason of a massive wearout of gears which ofcourse produces a lot of noise.
The bearing wouldn't be grinding like that. Bearings whine and then suddenly lock up after a long time. This is more likely a pinion tooth or two.
If the bearings died months ago, and they kept using the drive, both of the shafts could be very eroded where the bearings sit. I’ve fixed / remanufactured many an industrial conveyor shaft that was eroded to half its diameter where the bearing used to be before it simply broke, stopping production, and they are forced to make a repair. If it works don’t fix it isn’t the boating or the aircraft way, but you guys know that of course. Just had to tell my little story. Happy sailing you two.
Minor step back.. But better now. This way you will know your engine quite good and have a much better understanding of its limits. Love you guys!
It’s sounds to me like there’s a broken tooth off one of the gears. I’ve heard that before. That’s the rapping sound. And the bearings are toast. That’s scraping sound. Replace everything in the lower unit.
I can complete relate; docking is sooo stressful. I still have emotional scares from this experience! But you will get there!
Kika , your editing is outstanding...definitely ready for National Geographic’s! Are you using remote mics? Dan’s engineering insights are wonderful for a pseudo geek like me.
My heart grows for this channel
Hmm. With shavings in the oil, seems kinda like you had a leak compromise the oil which caused one of the bearings to wear down. Looking forward to part 2
Agree a bearing in its way out. I would guess as a result of sea water getting in, presumably there is a damaged seal.
think its the other way around. there was/is a bearing broke or not fitting wel that made the leake and the noise.
@@kapteinron anyway,,,what a drive...crapping up after five years???
@@tiborkiss9186 - It all depends on how it was maintained and used by the previous owner. Some cars last a long time and some cars are piles of crap after just a few years and it's all due to maintenance and use. Sail drives and other things are no different.
@@kapteinron Perhaps
Nice shots of the old fisherman’s town of Enkhuizen with the houses, bridges and bikes.
Hope you are having a nice time there while reparing the problem with the prop.
Can't wait until you get it pulled and fixed. The more of these electric motor vids i see the more i like the idea.
My country is crammed with beautiful towns with lots of 16th and 17th century buildings. Of these Hoorn and Enkhuizen i.m.o. stand out as the best preserved. I hope you find the time to look around and enjoy. Kudos to Oceanvolt for their service, it will no doubt save you a lot of trouble when this problem is taken good care of.
Sounds like a worn bearing, hopefully you've caught it early and it doesn't cost too much.
Sounds like a flat spot: the reason they're likely not hearing it in forwards is its likely not rolling any more, just sliding: in reverse it's rolling so you hear that tick tick tick. (someone else mentioned gears climbing... Let's hope it's not that bad!)
Maybe it's worn, maybe it took a light strike at some point (it happens). I have no experience with sail drives, but I've heard they're a nightmare, so I'm looking forward to the followup video.
It does sound like a bearing spall. As speed increases the frequency increases and it sounds different.
Lots of support from OceanVolt to your issue. Lovely place to break down. Enjoy your stay.
What a cliff hanger!
Got chills seeing Uma coming onto the hard. Fingers crossed. Love you all.
Better there than having the motor dying when you need it.
Ya it’s fucked, bearing are shot!
So lucky to have such helpful fans of your channel. They are awesome.
To be continued.... I’m wondering did you load any software motor characteristics into the engines management system? Just like a car it could have insane acceleration, but that might rip it out of your boat.
Well....that sucks! But on a high note, you discovered this early, have experts on hand, and can repair it without having to ship parts half way around the world. So for a breakdown, this was probably the best time and place for it! Actually, it's not really a breakdown, it's catching a problem before a breakdown occurs. Which is always preferable. An old mechanic friend of mine has always said "learn to listen to your car (boat), she will tell you when something is wrong, well before something breaks". So now you know what your sail drive sounds like when it's sick, and afterwards when it's repaired, you'll know how it sounds when it's healthy. A valuable lesson to learn and remember. Cheers from Winnipeg.
You got lucky that this problem was found now, and not in somewhere middle of nowhere..
Sounded like the gears in the sail drive when I heard it a few steps ago. Be interested to see what they come up with. Good for them for standing behind their product.
Uma is flying :)
sounds like she's dying
a great engine gear analysis I like that old engine trick Ive used it for many years and the new mecanics could never figure out how i did it Kudos to your dad Yes im 70 years old Happy fathers day s
May you should have left the old drive shaft in place after all?
