First sea trial

- In this video I fix up all the electrical gremlins from last week, align the engine more accurately then go for a short sea trial. There was still a noticeable vibration in the gearbox so I dropped the boat off with Mick at Coast Marine. Looks like we are going to need to re-jig the way the gearbox and the propshaft attach, which will require pulling the boat out of the water, but I'm very keen to get this problem sorted properly so the boat will be reliable for years to come.

When Stu was hand-spinning the prop shaft I imagined the mollusks and barnacles on the prop getting into theological arguments - whether these events portended the Great Spin or not.
LOL
That’s hilarious! What a great imagination!
I'm deployed right now with the U.S Army and I've been watching since the start of the project. It's awesome seeing her run and I'm beyond thrilled. I look forward to your videos because in a sandy hell hole. It's nice seeing things come together. Hopefully for a long road ahead.
NoT So keep safe bloke.
@NoT So - Guess you didn't realize the Army has quite a few boats. Mostly tugs and landing craft. Best kept secret in the Army. Served on them in the late 60's across the big pond. Stay safe brother.
Go Navy! Bear Army!!! (USN 85-91)
Thanks mate, stay safe. :)
Thank you Stu for seeing this project through. Watching your videos have become the highlight of many of our days and weeks as we are stuck at home. You have done much more than rebuild a boat. You have taken our minds off the serious issues the world faces and given us hope that one day our lives will return to some sort of normalcy. I wish that one day I can see your beautiful island and perhaps buy you a beer or at least shake your hand, well at least an elbow bump. Thanks again.
Thanks Ben, look forward to that elbow bump. :)
the old boat population is gonna have a good day. 138000 people know it can be done. love to watch the struggle and the victory. You've done good , proud of ya.
Thanks Gareth!
“Obviously I wasn’t such a smart shunt...” 🤣 Priceless.
Never clicked a video so fast
It showed the video had been up for 1 minute and already had 100 views!
APARTMENT .223 same here
me too
Just my opinion but I believe everyone is extremely excited for you Stu. So happy you brought us along with you. It's has been a very bright spot in my day when you post. Can't wait for more content.
Great job Stu!! Great to see your underway.
I stumbled onto the first episode of this series by chance ,where you bought the boat. I was immediately hooked and binge watched the whole lot over 4 days. Sitting here in the UK with grey skies and about 10 Celsius outside while being under lockdown, it’s been brilliant to see you working away on this project in subtropical conditions in wonderful oz. Absolutely fantastic series , good enough to be on the telly. Many thanks. 😷🇦🇺🇬🇧
Thannks mate, glad you enojoyed the series. :)
It warms my heart to see the boat working under its own power. Great work Stu
After a rehabbing an older boat I eagerly took the family for a weekend on the water. My father has many years of marine mechanic work behind him was aboard. I was very nervous about slight misses of the older Suzuki DT115 and this and that. He started laughing....pointing out all noises and vibrations sound/feel worse the further from home you are. He also pointed out that it is a long walk home from anywhere on the water. Wisdom of those that have been there before.
Congrats Stu!
Yes, it certainly is a time that you are really listening and looking for any sign of trouble.
That's cool seeing you on the move all the work paying off at a time when our lives have been changed so much thanks.
Cracking a beer for you tonight Stu. Congratulations!
Stu you have completed several enormous jobs to enable you to start that engine and move your dream across the bay. Allow me to add my
Congratulations for a job well done! I am certain any remaining problems will be well taken care off. Proud of you sir!
Thanks mate. :)
The chickens were very happy, it was the right hand to them. All of your fans are very happy for you! You are the best marine mechanic & teacher BAR NONE. Because of you I have become more maniacally inclined by the day.... LOL
Hi Stu! Arch from Maryland USA. It's 1am here on the East coast of USA. When you were using the socket and feeler gauge you were getting close. I have used many methods including laser alignment tools that would show you all 4 feet positions and which direction for them to go. If the Prop shaft and drive hubs can be bought close, then one checks 4 - 90 positions for clearance. The faces have to be clean machined surfaces to measure. The wobble in the gear drive appears to be up and down misalignment. Hopefully your expert will make it right. Congrats on a hard fought win!
Congratulations! Do your engine room a favor and build a shroud around the shaft packing to keep any salt spray from the slinging around when underway. Big piece of PVC would work.
Bad Santa Bon idee
Yes, it does get thrown around a bit more than I was expecting. A shroud is a good idea.
@@DangarMarine We have a 1/2 round of aluminum mounted around the shaft/packing area. About 14" diameter or so. Trick is to make it easy on/off to service the packing. Keep at it team Zissou!
Dangar Marine check out any jet ski
So happy to see her under her own power. Congratulations Stu you did a fantastic job!
Very happy to see Renko under it's own power.
Your hard work has paid off.
It won't be long before you are out fishing and diving.
Your patience towards getting it done right is inspiring. The complexity of a lot of this stuff is quite intimidating and requires great attention to detail. Awesome!
This video is a godsend. My wife has been standing at the living room window for days staring endlessly. Sometimes she even cries. I want to make her happy and have even considered letting her back in, but rules are rules ......
LOL
Ran across this channel yesterday and picked a video somewhere around hoisting the new engine onto Stu's boat. That late evening I watched every video in backwards order to the first test run.
It is a fantastic tutorial for boat owners who may have just purchased their new boat and might be a little intimidated to get straight into their engine rooms and start learning how to do maintenance yourself. At least to a point of knowing how-to and get to know your boat
Thanks for watching!
CONGRATULATIONS! Quite the project no wonder you feel every vibration and every odd noise you're very protective of your baby. Great job and thanks for sharing.
Timing couldn't be better on my end. Thanks I was beginning to loose sleep over this! lol
You've done a great job. I bet you are happy to have her moving under power.
CONGRATULATIONS ! Maybe not the maiden voyage you hoped for, but she's a runner !
Congratulations! So great so see Renko moving under her own steam! A real labour of love.
Hey Stu, Im over the moon to see Ranko on the way under its own steem! I have watched the dream come true since day 1. Congrats to Capitan on believing its possible to dream.
Thanks mate!
Alignments are tough on a machine with resilient mountings. When you do it again there is an order which must be followed otherwise you are just chasing your tail. Horizontal angular first, then horizontal alignment. Then you can sort the vertical axis which is easier. Also clean up the gearbox flange, you would be surprised how thick paint can be. As experience I used to align air con and refrigeration compressor motor sets so have done many of these. Good work though, keep it up
Thanks mate, appreciate the tips.
I agree. A 10:20 if the front of the motor was shifted, then the entire alignment that was previously done would need to be repeated.
Oh Stu! How nice to see her moving under her own power! Congratulations!
Good day mate.
After you dial in the run-out around the coupler, slide the prop shaft down and mount your indicator so the needle is on the face of coupler. Dial that in too. Remember that adjusting this run-out will affect the run out on the o.d. so work in halves until you're very close on both.
Free the top nuts of the engine mount studs before starting so that you're not forcing the block or mounts to twist. Also, remembering that when adjusting the horizontal axis the mount you are not moving becomes a fulcrum for the engine to pivot on, and measuring the distance between mounts and cross multiplying the error/span by x/mount spacing will allow you to calculate an exact adjustment and get you very close first time.
Anyway, indicating flange and face will ensure the two axes are concentric, not just at the point of the flange but along their axes of rotation. (Think of two lines and the coupler is the point at which they pivot)
I literally locked my wife out of the house so I could watch this long awaited episode in peace , congrats stu awesome job mate
I am a locksmith and I wouldn't even be game to lock the missus out. Well played sir😁
he just cant let her back in now!!lol
Thanks mate. Apologise to your wife for me. ;)
Bad news Brad. The Year of Living Dangerously was last year. 😳
Congratulations on a great milestone👏
So awesome to see Renko under her own steam. Albeit for a short trip, but still very much a pleasure to see Stu.
Glad to see her move under her own power, congratulations Stu. It's been a long time coming but well worth the wait.
This is the one we have been waiting for !
Stu, congrats on the major milestone!
You are a beast, man I would not have the balls to take on a project that size. I have learned a lot about these steel boats from your videos. So cool to watch!
I worked in a boat yard for many years i I’m here to tell you your completely on track but I think you know that good man yourself!
Congratulations on this wonderful achievement.
Another great episode mate, Thanks!
That was awesome to see her move under her own power after all that work. Congrats and hopefully the shaft alignment problem remains a simple problem.🎉🎉🎉
never restored a boat, several bikes and a couple of cars, but I do understand the dark spaces you get into when you cannot see the project ever being finished , but that first journey finished or not (and truth be told they never are ) is worth it , fabulous achievement my friend , but be advised you have let your Gennie out of the bottle it wont be your last project.....
Thanks Ian. :)
Congrats Stu! Long time coming. Great work!
Good to see it finally off and cruising.
Congratulations on sea trials at last. You are right to have Mick check the vibration, better safe than sorry. Nice job mate!
Yeah, I want to have 100% confidence in it. I think there is more to the vibration than just tweaking the alignment but we'll get it fixed up.
Congratulations Stu on getting the boat motoring under its' own power. I know there's more to do but milestones are to be celebrated and that, in my mind, was a big one. Keep up the good work and I'm sure you can see the light at the end of the tunnel now. Cheers biggest ears.
Thanks mate. You're right about needing to celebrate the milestones along the way. All long journeys need breaking up into achievable steps!
Wow it feels like just yesterday that you started this adventure, glad I was able tio follow along. Congrats on finally getting it running.
Dude I am soooooo happy for you.. great job.
Very pleased to see the trawler moving. Great work Stu!
The prop alignment bit was fascinating! I know it's so important as I used to teach English to Wartsila engineers in Finland, and mating a big diesel to an ABB generator on the same chassis was critical. On the lighter side, a friend of mine has a Dutch barge, powered by an old bus engine joined to the prop shaft with a universal joint! As for me, I have a hydraulic drive, so the only connection with the prop is via hydraulic pipes :-)
I would love to have the room for a universal or CV joint, but hydaulic lines is even better! The other good option would be cables going from a diesel generator to an electric motor. :)
Woohoo Stu, you just brightened my day.
That's brightened my day! Just the notification have not watched yet!
Great moment to see the old girl under her own power! Cant wait to see more of her going places. Oh yeah you as well stu
Ok, STU we heard you loud and clear...Its time for a BIGGER boat project...Show us a sneak peak at what you have your eye on...I'm ready....
Don't have my eye on anything in particular yet, other than going back down to Sydney Harbour to help Troy with his timber trawler. I'm not in any rush so I think I'll really take my time in finding the right boat to work on next.
I reckon you're not only a smart shunt but also a clever and a cheeky shunt. Nice one, good to see you are underway, well done Stu 👏👍
Has it been 18 months!!!! Where did that time go?
What an outstanding achievement. Having restored a boat myself (much smaller project than this) I know first hand what you go through. It's been obvious that you've struggled at the latter stages with boat resto fatigue but you've battled through. There's some nice jobs now as you move on to the cosmetics and good stuff.
Well done Stu.
Well... I was mostly at the pub. That might explain it.
Was thinking pretty much the same thing. Where did the time go?
Thanks mate. I'm definitely looking forward to getting on with some of the more fun jobs, the grind really was starting to burn me out big time.
instaBlaster...
Great to see First sea trial. Super project that we all learnt from. Far larger project than I could have handled but great to learn the process.
Congratulations on the first run down the coast. We have been as looking forward to it almost as much as you! Great job Stu!
0:58 "I'm afraid i can't let you do that Stu..."
Hal lives on
Open the Seacock Valves, Renko...
Well done mate - what an achievement! Sensible to have your work checked as well. I'm inspired to put more work into my own projects
Stu, been an automotive tech for 30+ years. Every once in a while you gotta have someone with more hands on experience with a particular situation take a second look. You made the right call IMO. More videos, isolation boredom sucks.
Thanks mate. For sure, there have been a few times when I've got an expert to take a look (Adrian with the Detroit for example) and it really saved me a huge amount of heart ache. There is no way I would have know that the blower should spin more freely than it did and I would have just tried to start it. The right advice at the right time is worth its weight in gold.
Congratulations man. Very happy for you and glad that you took us along for the ride for these last 18 months.
Congratulations Stu she's finally pushing through water cheers buddy.
How amazing, you did it, she's wonderful, and it's born from your very hand!! Congratulations my friend, you deserve it!!
Well done Stu, very exciting and good to see the old girl pushing water from front to back. It’s taken a few episodes to get here but it’s been well worth the journey and exciting to see. Well done buddy. Look forward to the up and coming.
Great job mate. All the work was worth it. She looks beautiful on the water and the Detroit sings a sweet sea song. I was working on the island of St Kitts for a year and a half and followed you since you bought her. Just got home to So Florida recently and you’re on the water again. All is right with our worlds. If we can get past this virus thing the rest of the world will be right too. Stay safe. Enjoy!!
You've done a great job, getting alignments like that are rough to do. I have had my fair share of them. Sometimes close isn't close enough. Amazing how just 5 or 10 thousandths can make such a big difference! Your getting there, no huge problems. 20 psi on a hot Detroit is good. We ran one for 2 years with only 10 psi before finally rebuilding it! Good luck on the rest of it!
Good show, Stu. Proudly and regularly wearing your T-Shirt in San Diego, CA.
Thanks mate. :)
Stu, absolutely awesome to see Renko moving under her own power after all this time!! Good call on having an expert take a look at the alignment that amount of flex on a cast housing would not end well. Looking forward to the next installment!!
Yes, I think that casting was not too many hours of running away from breaking for sure.
Congratulations Stu - all your hard work has paid off. 🥳 It’s also clever how you turned a chicken into a goose! 😂
Sweet! Good on ya Stu ! Made my day ; )
The 20 people who disliked this should take a long walk down a short pier.
Or hate stink boats.
They weren't expecting solid technical know how; but, the usual Tits & Arses shown on most other yacht/boating channels...!
They are the same people who are crying that humans are causing "Global War" I mean, " Global Cooli" no no, "Climate Change;-) by using oil to power the world... And cheap nuclear plnts are going to blow up and kill everyone, hydroelectric dams prevent fish from migrating, windmills kill too many birds, and coal pollutes the air! I would say these are the same people who want us to heat and light our houses with wood, but that would entail "Murdering trees"!
Killing the dissenters is worse than the dissent. Your generations failure to learn this valuable historical lesson is why the modern Progressive anti Liberal west is collapsing in on itself in 2021.
Gotta admit; I got a little chocked up watching Renko moving for the first time. Great job Stu!
Thanks Peter. :)
So very happy for your first run in Renko after so much work! Very satisfying for us to watch too.
Perfect timing, cheers
You need to put together a montage of what it was like when you first picked it up to now. Think it would be fun to see the progress in a nicely edited little video
Unfortunately I delete each video off my computer as soon as they are finished, but I might be able to download back off UA-cam.
@@DangarMarine that would be awesome once you get the majority of the craft done! Cheers on the progress regardless!
Under its own steam! Congratulations! So much work, well done, Stu! And well done, clucks!
Hi there, just a quick note to add my congratulations to those of everyone else. Superhuman effort. Happy voyaging. Cheers, Jonathan
Thanks Jonathan. :)
Stu, when doing coupling and shaft alignments, both should be rotated together to ensure that any runout of the machining of the od of the coupling, corrosion etc don’t give false readings. Basic alignment 101.
Great comment! Stu has just made the flanges align I think?
Cleaning off the Paint and cleaning same with emery cloth would have brought up that machined surface so clocking around the static machined coupling would have had the a very similar effect, as same would have been machined true and concentric to fit the crankshaft, "Needs Must" sometimes... twas a great effort, anyhow it's now in a Maritime Hospital under the care of a good surgeon we are all waiting for a diagnosis, i thinking that their may be the likes of larger more agricultural engine pads to be fitted might help and same could relieve the wobbling which is currently at play...anyhow we shall have to wait and see seriously looking forward to your next Upload, Great Work and congratulations Stu, after same one would need a case of "Cooper Ale" as required medicine.
malachy1847 as I advised above, both coupling flanges should be rotated together so that the readings are taken on the same exact surfaces at each point. This is basic alignment procedure. While it is possible to get the alignment close by turning only 1 flange, is is far from accurate. For the novices, there is the mechanical engineering bible that is a great guide for both novices and also those that wish to refresh their memory.
You’ve done a great job Stu, don’t take my post as criticism, I’m just trying to help with my personal experience of over 40 years.
Keep up the good work mate, and always remember to ask the questions and listen to all the answers to be able to make the right decision on which advice to follow👍🍻
Nuff Said Mate I think the thing is here is that Stu had a go and all advice including yours would have been great in hindsight. That’s why so many are watching.
The best way to get accurate readings with a ir thermometer on different surfaces is to put something on the surfaces. I personally use masking tape.
Congratulations
You've done a great job. Some minor things left to fix but the boat is moving great. You deserve it.
Always nice to be on the water, but extra nice after all the work. Congratulations.
YEE HAAA Congrats
Hey STU, we are craving a video sitting around home here. I sure you have a project or two around your work shop to go over with us. Wipe down tools or something.lol...
Wow Stu that prop shaft and engine alignment has been a hell of a job..you sure there's no banana's on board.
I have never viewed this channel before but then I recognized the bridges and I used to live on Dangar Island. The moment the engine started I recognized the sound of a Detroit and those gearboxes need to check the fluid level with the engine running. Glad your going and I don't know why I didn't make the connection before.
Thanks mate. Makes sense the gearbox level needs to be checked running like an automatic car.
A non rusting container with a small bilge pump located under the prop shaft drip works well . . .
Yep- a plastic oil container or a square chemical drum in plastic is cheap & easy to cut around.
Love it how youtube's subtitel says: this video is "probably" sponsored by marine engine
LOL
So many months, so many hours, the days that you were exhausted to the days you conquered some big obstacle. I am thrilled for a guy on the opposite side of the earth who has offered the rest of us the opportunity to watch a massive project. To see you piloting under power.. amazing!
Thank you, Stu.
Thanks Brian. :)
Ha! As soon as I saw the notice I clicked to watch. So exciting! Let the adventures begin. Can’t wait to see more water drone footage
Just to ease your mind. The Detroits were infamous for having a low minimum hot idle oil pressure spec. Haven't looked at a book for a long time but I believe 10 PSI hot idle was perfectly fine.
Yes, I've done a bit of research since and that does seem to be a characteristic of these Detroits. Phew! :)
Ive seen them low as 8lbs psi on low block gray marine 671s
On the 6-71s on my boat I would idle in at 750 rpm when hot to keep the oil pressure at 10 psi. Any slower and the oil pressure got scary low. Normal op speed oil pressure was about 30-35 psi.
I never liked to put much of a load on my Detroits at idle, their like a two stroke dirt bike and love higher revs. ( had a couple, one in a Northwest dragline crane, another in a Warner Swassey hydrahoe ). Low idle oil pressure is normal in Older Detroits.
We had several dump trucks with them and a wheel loader with a 4-71. The wheel loader came out of a Quarry and they had run it for years with a straight pipe, no muffler.
It ran fine but first thing I did was put a muffler on it. You could here it working from a mile away.
good job on aligning the shaft.
I would suggest that before putting the dial gauge on the motor flange that the flange is dressed clean first as the paint thickness or it being originally out of round may throw your measurements out.
For the uninitiated, to dress the flange, just start the motor with the tail shaft disconnected and put it into gear. on the spinning flange hold a file to it propped against a packer and gentle smooth off the surface. common sense is needed but dressing is essential.
Also, the drive damper. What is the spec. on it, for bolt anchor location deviation from the common center? That or a warped flange, trans output or shaft coupling (hopefully), or the shaft needing straightening.
Cheers all, stay safe
Yes, I did wonder how much the paint would be affecting the dial gauge. It certainly got the alignment more accurate but dressing the surface makes perfect sense.
Well, you certainly haven't made the boat any worse:-)
Congrats Stu!!!
Well done Stu. Great to see her finally move.
Isn't it the shafts that need to be in alignment, rather than the perimeter of the flanges? They might not have been machined round and concentric? I think shaft alignment is an entire specialty unto itself in some trades.
I'm curious about your friend's verdict, too. When the dial indicator comes out, things are getting quite fussy. Chasing perfect is a losing battle....
I thought that is well...
Was thinking the same, and feeler gauges where there is paint (chipped and probably non-linear thickness ).
A Marine shaft should have The flange mounted on it, turned and faced true. This should happen whenever a new shaft is made, and the old flange is reused also
Yeah, but...
@@leeh.4453 Ya...
transmission in neutral and spin the gearbox flange....
Yup..
Yep. Needs to be one bolt in it still so they spin together, otherwise you are reading the imperfections in the flange.
@@davidthompson6099 please clarify what you mean....
@@1oldteck I presume he means that you want to read the varying orientation/offset between shaft and gearbox flange. In a perfect world, you could just keep one stationary, but this assumes that the surface of the flange perfect. Of course, it won't be, and so you read the offset + any (varying) deviations from the assumed perfect surface if you drag the indicater across a stationary flange.
@@1oldteck you need to turn the shaft, and the gearbox flange at the same time to get the correct reading. Otherwise things like paint, dings in the metal or it just plain not being perfectly round will affect the readings of the dial indicator. For best measurement, the gearbox should be warm from running as well as heat expansion will move things around too.
Well done Stu - That man deserves a beer or 3!
Well done sir!! Very exciting to see her moving under her own power.
Always enjoy the sound of the 71 diesel. Thank you for the videos.
Outstanding, Stu! 👍🚤 Thanks for taking us along, looking forward to more! Cheers-
Stu a massive congratulations on a huge job done well. Thanks for taking us on the journey, both today and the last 18 months. I hope you get an awful amount of pleasure and satisfaction from all the Renko adventures ahead!
Thanks mate. :)
Renko moves under her own power! Awesome.
