No oil on the dipstick? First loosen the oil fill cap, then recheck. If cold, sealed system can vacuum down level on the dipstick tube/dipstick. Unscrewing the fill cap allows the pressure to equalize.
Your videos are really a joy to watch, you really explain things very well. By far this is the best most informative boating channel on UA-cam.
Wow, thank you!
Totally agree … super informative
Second that !
Thanks for a great video, learning about lower unit seals. Re oil changes, to be kind to the engine, I like to prefill the oil filter with the new oil and pull the fuel pump fuse and crank engine to pre lube the engine after an oil change. On yamahas, the fuel pump fuse is lableled but typically top right 20A fuse.
Thanks again for another great video! Haven’t even thought about thermostat replacement. Going to check mine out and see what condition it is in. My fuel filter and water separators are on the list soon so I will check thermostat then. I do appreciate all the work you do Aaron. Saves me 💴and a ton of headaches. 👍👍👍😎🌴 stay safe out there!
Glad it was helpful!
This is an excellent video on how to maintain a 4-stroke. I wish I had this when I was first learning.
Sensational video, really covers a lot of important servicing points quickly and professionally. Video, audio and narration perfect in every way.
Glad you enjoyed it!
Again another informative video!! i have a 2017 Mercury 150 4 stroke with almost 400 hrs. I do a complete service every 100hrs ! me personally find this engine the easiest to do, for the price of all mercury parts and oil (minus the thermostat its the most expensive cause the housing comes with it) . then when the service is finished i spray the entire engine with a fogging oil to protect everything from the salt! it looks and runs the same as the day i bought it new! some of my friends say im wasting money doing everything at 100 hrs, me well that puts me more involved and hands on! Ive been all over the central east coast of fl and the keys with this boat and yet to find a parts house 30 miles off shore!
Keep up the great work!
Always enjoy watching your videos to see if I miss anything during servicing of my outboards. Keep up the great work and spreading your knowledge.
Thanks 👍
I really enjoy watching these videos and series. Such a helpful wealth of knowledge. Easy to follow and understand also.
Great to hear!
Another amazing video ! Great info. I will keep up with all maintenance on my new outboards so hopefully will have many many years of use.
Glad to help!
nice Leatherman, i got 2 one in car 1 in boat gotta love how good quality and handy it is.
Great video, thanks! One tip on the spark plug/coil boots is use a small amount of dielectric grease. Once again, thanks for the details on the bottom end!
Great point!
great video. you make youtube much more interesting! thanks. regard from straits of malacca.
Amazing job with al your videos! Always great content!! :) Best regards from Sweden
Thank you very much!
Your videos are so informative, it really makes a difference
Glad to be of help :)
cool, i did a merc fuel injected 150 today. learned alot, made a few mistakes to not do again.
Preventive maintenance is the key to longevity!!
great; just the claw hammer mate, buy a soft end hammer raw hide or nylon, les idiot rash. everything else is mint!!! love the vids
Infowars on the toolbox! Well informed I see! Awesome videos!
Awesome as always. Best channel on UA-cam. Thank you.
Glad you enjoy it!
I love these kind of videos! People who neglect things like that deserve to be overcharged.
thanks for your feedback!
I have used a can of compressed air with a nozzle tube, and a straightened paper clip with good results. Your videos are very helpful! Thanks! JAW
Cool, thanks
I am retiring from Las Vegas to Florida next year. I can't wait to get a boat and do my own maintenance. Your videos are awesome!
Awesome! Thank you!
Pulling out that thermostat looked like you was pulling a whelk from it's shell hahahah
Good video.
I thought one part missed was greasing the prop shaft. Anyone that has ever had to deal with a seized prop, on a shaft, can relate.
Thanks
Your videos are great ! Jim in NJ
Good video.!! The woodruff key on the lower unit can be a pain to remove sometimes.!! Thanks for sharing.
Thanks for watching!
When you’re using the oil drain hose on the Yamaha, are you threading a fitting into the drain hole, or are you just shoving the hose in?
And what size hose?
Thanks for sharing your knowledge!
I love seeing InfoWars stickers on your tool carts.
Cardboard oil deflector..Brilliant. Thanks, good video
Thanks for watching!
Another great video. Just found one of my housing for the t stats on my 2003 Yamaha f225 has corroded through... ugh. New engine time
Good luck!
That was a great video indeed. Awesome mate.
Thanks for the visit
Super great video as always!
Thank you! Cheers!
8:27 I slide the old impeller over top of the cap. Simply slide the impeller on ...then tap it with the hammer instead of the new cap
Thank you!!! Very informative video!!!!
You are so welcome!
Hi B.A.B, Thank you for another video with an amazing amount of information! You really are amazing. I was one of your first subscribers, and I told you then that you will become the Most-Watched How-to-do boat repairs on UA-cam... I would LOVE it if you ever come across a 2014 Yamaha 300, and can show this type same video, I will GUARANTEE you will, be in the WILL!! ☺ I do a lot of my own maintenance but I don't know even how to get the plastic covers off to access the spark plugs, internal engine-zincs and thermostats... UA-cam people; please no mean comments;. I'm just an old dude; looking for help...
Thank you Andrew! You have always been super supportive :) Hey, I know this isn't our best video, but isn't this your engine: ua-cam.com/video/S5BPuWP6VnI/v-deo.html
@@BornAgainBoating YES! This is it; Thank you! I don't know how I missed this one ; I more likely just forgot.... Thank you once more!...
I notice you do not use dielectric grease on electrical connections. Is there a reason for that?
OMG, I saw that big boat on Sombaro Key reef last week. I hope you were not on it. He came by very fast and close. Our group was like WT heck?! Great video, as usual.
Oh wow!
Brilliant video
Appreciate your comment!
Anyone have suggestions on where to find rigging a remote oils tank for a 4 stroke?!
Nice job well done 👍
Thanks for the visit
When you put the lower unit on does neutral apply to digital shifting aswell or just cable? Obviously gonna put in neutral still lol. Also you should do a 7 marine maintenance.
Yes, keep the lower in neutral for digital engines as well :) I would love to do a 7 marine service video lol if only they didn't cost $100K and I could get my hands on one lol
Marine tech here again, I tend to prefer to use an oil extractor on the older yamahas, I've seen some where previous owner had done his own oil change, cross threaded the drain plug and it was leaking, upon removing the drain plug, it cracked a piece off the oil Pan, we had to remove the entire power head, disassemble the mid section and remove and replace the oil pan. It sucked
Wow nice 👍🏻 good to know
And how often exactly should one break this down to this level? I know everyone will have a different opinion but just curious. Also, at how many hours should you do what exactly? Does that make sense?
Preventative Maintenance beats reactive maintenance every time.
Hi born again, I just bought a 04 cobia 184 with a f115 it only has 200hrs on it. Is there any thing you recommend me doing to it as a proactive preventative measures as it is a 17 year old motor. I'm referring to having the lower unit resealed or new belt and pully. Or if there is any other advise you can give me on this motor would be vary appreciated
I have a 225 honda, I changed the thermostats but the engine was getting hot a lot, so I took them out, it has ran great since ! My engine now has 2600 h,
Thanks for sharing
And that in my opinion is why Outboards are better than inboard outboard! I didn't see you stand on your head one time to reach the oil drain plug or anything🤣🤣
I just bought a 72 222 Aquasport with a Yamaha 150 that has a lot of hours. I went to grease the motor and most the fittings are missing. What is the best action to take for replacement. Also what is a good site for best price and quality parts for a restoration. Thank you.
good job
finally seeing some Suzuki's.. ;)
But no evinrude
Thank you for the video . I am far from an expert here but for me the new merc 150 is probably the easiest to service . I serviced my daughters 150 and did not spill a drop of oil either from the filter or the drain tube . The filter has a catch basin which I thought was pretty damn cool . Also Merc has put everything on line . I don't know what the dealers thing of that though . Just an observation here on my Mariner 75 hp I was told not to put grease on the top of the drive shaft when replacing the lower end but to just put it on the splines . Something about causing a hydraulic lock . Is that true ??
Yes, just the splines, because if you put it on the top, then it will stop the drives haft from going all the way to the top and youll develop a bunch of grease in he crank and it can create a larger load on the drives haft bearings over time. So just hit the splines :)
Really like videos! If you get a chance can you some videos on inboard outboards?
Yes, but we don't see many down here :(
Love your videos! Where are you located?
Sebastian FL
Any chance you can do a 1999 2 stroke Mercury 225 EFI.. i am a new boat owner and I am a huge DIY guy. Would love to repair or continue doing PM to my motor. Need a goto video. Thanks in advance.
We don't see a lot of those engines down here anymore :/
Just one thing though: we mechanics (I am a mechanic myself) don't just lubricate the parts and components for easier assembly and disassembly do we now? We mainly do because it's better. And because by lubricating it, the material won't get damaged! That's actually the main reason why we do it don't we now? Beautiful video though😁
Awesome, thx for the tip. How about the mercury lower unit. Thanks
It basically looks the same as the Yamaha :) I guess I should put together a lower unit video with a couple different lowers lol
@@BornAgainBoating yes, that would be super,aloha. Thx
I have owned Mercs since 1962, people think outboards last forever, with good maintence, fresh fuel and Merc oil they will, funny when people throw off on a brand and never service, and then it quits.
92 Merc 2.5 200 still screaming on a procraft 18.5
Great video.
Thanks man
Where can I find a list of what to service and when for 2014 Yamaha 250s? The 3.4 L version?
www.boats.net/catalog/yamaha/outboard-by-year/2006-and-later/250hp/f250xca-0114/scheduled-service-parts
Those are your parts, then just follow your 100 hour or yearly service intervals depending on how you run the boat :) and then the 300 hour service intervals: Also check this out: ua-cam.com/video/zYtONslzxTM/v-deo.html
Why is there no oil filter on my 6hp 4 stroke?
wait... so if i service my engine it will last longer?
Nice 👏👏
Thanks 😊
Another great video. I would like to ask you and all of your viewers for some advice. I’m nearing retirement (within the next few years). I’m a HVAC tech so my pockets aren’t that deep. I want to make the switch from a bass boat to a blue water boat. Meaning I want to be able to go out to where the big fish live off the South Carolina coast. What would be your and your viewers recommendations as to the boat and motor size that I would need to fish like I want? I can’t afford anything new. Anything I buy would have to be at least 10 years old so as to fit my budget. Any all advice would be appreciated. Thanks again.
I'd say to look at boats around 24-28 ft. They're big enough to give you more options of being safer when storms pop up and easier to fish. For a nice cheaper boat, look into Dusky. They ride great and aren't over priced.
If your looking for something with a few years on it I would concentrate on finding an older hull that some one replaced the out board all ready so your starting off with a newer engine, boat hulls usually dont go bad over time but an older outboard can develop issues over the years, good luck
great!
What is that Blue Grease (Name/Brand) that you seem to use on everything??

Hello, my question is unrelated to this video but I was wondering if you could help.
I've searched high and low, but everyone has a different saying on this.. maybe you know..
Is it possible to convert a Yamaha four stroke f9.9 to 15hp by swapping the reed valve from a 15hp motor to let more air in?
I heard it could be done, but I'm concerned about timing, air/fuel mixture not being the same with the reed valve from the 15hp motor..
Oh btw.. I'm in South FL and your channel is awesome!
Hello, not sure, without looking into it :/
I'm an avid watcher of you're channel. I have a request for you. My vinyl seats are starting to show some fading and was wondering if you can do a video on restoring them. Hopefully its something in you're realm. I'm not sure Wich products to trust.
Cleaning really isn't my strong point. I've been working on getting to do a job with a detailer to learn more about it though. So maybe sometime in the future
Is it a common thing in outboards to "make oil"? You mentioned the yamaha oil level was high. I'm assuming it's because the thermostat was stuck open not allowing the engine to heat up properly.
It isn't "making oil" from a stuck open thermostat. Someone just put too much oil in it. Likely put a full quart in it when it only needed a half quart etc. The oil level would only go up otherwise if it had water or fuel in it. The oil wasn't milky so no water in it. Fuel diluting the oil makes the oil very thin and generally you can smell the gas in it. That open thermostat isn't as much of a factor here in South Florida because its usually warm/hot here.
Yes, depending on the brands. Mainly certain Yamaha's "make oil" but it's really just pushing fuel into the oil and that is why it is high. Those F115's never really had that problem though, so someone probably just over filled it on this engine :)
Do you have your own shop or work for one? Also, how can I get started as a marine mechanic/tech?
I just work at a shop, I don't own one :/ I would say to find a shop near you and figure out how to get in the door and just try and shadow another tech. Make sure you are teachable and that would be a great start!
Don't think you used quite enough grease bud, I can still see the parts.
Don't forget to use wr2 grease on the driveshaft splines going to the powerhead. I used marine grease and my motor started squeeling. Come to find out it takes a Yamaha wr2 grease
What is wr2 grease?
I need a new lower unit for my F150, and I was looking at stern drive engineering because of price. Any experience with these lowers?

Good video iam mecánico of outboard i working in ny
Do any of the motors you work on have an hour meter in them?
Almost all of them now keep the hours on the engine's computer so you can always check the hours :)
Hello boat lovers, I have a small 50hp mercury EFI , doing maybe 100-150hr a year , when should I change my timing belt ? its 2008 500hrs but looks pretty good. Thanks
They don't really have a specific time or hour to replace the belt at. They just say to inspect it every 100 hours and then if it has cracks, or is rotting, swollen, rough, or moves more than about 10 mm when you press in on it with your finger, then you need to replace it. You might not need to, but just inspect it with every service and then once you get closer to say 1,000 hours, go ahead and replace it just because it will be like 15 years old and almost 1,000 hours on it :)
@@BornAgainBoating best explanation ,Thanks .
What will the next contest prize be?
Not sure, I haven't had time to spend reaching out to companies for the prizes and then doing the contests :/
PLACE A Service ON yamaha bj 2012 F115 AETL 6E5-45318-00 BUSHING, DRIVE SHAFT ,and the timing belt.THE toothead belt quiche under load at 1300/1700 revolutions.Greetings from the Havelriver km 74,554 in Germany
should i do this at the end of the season or the beginning of the following season?
Depends on your usage, if you only need 1 service a year, you can do it at the end, you want to do some checks before storing the boat, seeing your talking about a season, you probably have to deal with freezing temperatures, so you don't want to have say water in your gearcase over the winter, so checking that is a must at the end of season.
But at the same time, now you are just having the oil and stuff sit over winter, not really like it makes a difference honestly, whether the parts are sitting on a shelf in a store or on your engine, just that now they are outside in the elements opposed to in a temp controlled store lol
I would probably lean towards the end of the season, depending on the usage and how long the off season is.
@@BornAgainBoating you rock! love your vids
and podcast, ty!
Where can I get the parts for my boat
You could get most of them from Amazon.com :)
Is it normal for an engine to lose oil but not an alarming amount within my 100hr interval I have lost maybe 1qt of oil! I run my yamaha 250 at about 4-5000 rpm for long day voyages! When I did my service it was at the half way point and now its right under the low mark! I have also been watching it drop because I check before every trip, but I wanted to really see if it was losing it fast or to me it seems normal?
I’m a diesel tech and it is normal in my opinion!
Um, lol, I wouldn't call it normal necessarily, but possible yes, what year is the engine? It could be signs of the oil pump failing and youll have to pull the powerhead and do a speedi sleeve. Do you ever see an oil sheen in the water? If not, don't worry about it and just keep an eye on it :)
Born Again Boating No oil sheen! Also its a 2010 with 900hrs purr’s like a kitten.
I can't find the oil drain on my Evinrude G2 😉😉
There's 4 that go through the transom 😁
Just a nit-pick: They don’t all require an oil filter. For example I believe Suzuki doesn’t use an oil filter until the DF8. 2.5/4/6 all use a screen that can be cleaned, but no filter.
Piston Ring Connecting Rods and Bearings (Valves) cost a fortune not to mention engine failure Downtime.
As with all my 4, 6 and 8 cylinder Car Motors I'll introduce a half liter of premium engine oil to a gasoline fill up.
I'd even consider a small bottle of Ames Oil in a 4 stroke Outboard (inboard/outboard too) when doing a gas fill up.
a fouled set of spark plus in a lot cheaper.
Just look at the size of that 4 stroke outboard engine Oil Filter?
4000 rpm for sustained running is a lot of wear and tear.

In Canada it hard to any service people that know anything and after norms Bayview marina sank my boat I service my own boat. YES sank it. in for universals and bellows, they drove it back to dock never checked it, and sank at the dock.
No gasket for thermostat?
Each model is different. some have a gasket, some just have the o-ring on the thermstat for the gasket. You'll have to look at your engine to see whether it has one or not.
@@BornAgainBoating Thanks! Great videos!
Wow
more inboard demonstrations?
We dont see a lot of them but I'm working on a way to get a couple videos of them ;]
What if im not getting the rpm and top end power that i should be and its not my prop or coils or plugs
2005 yam 225 turd 4 stroke
Fuel filters?
Born Again Boating i believe ive got them all covered, thinking maybe somewhere in fuel delivery. Would sea foam help clean injectors?
The question is " Making a Four Stroke last longer " and the answer is leave it on the shelf an get a Two Stroke !
Fairly simple procedures they just have to be done. Too many people neglect the simple service positions and pay the price later
claw hammers are made for carpenters
One of the most important things to do is flushing the engine properly
Bro, please use petroleum resistant disposable gloves. Used motor oil and gasoline are absorbed through the skin and are EXTREMELY harmful!☠
You are the 1st person beside myself I've seen put grease on an impeller, nice!
Only 350 hours 🤘
Pay me now or pay me more later. Maintenance saves money in the long run!
After watching this, I do not want to buy the boat any more
And to think I paid MMI thousands for the same information
A 2 stroke is cheeper and easy to rebuild.
Too many moving parts. Too much to go wrong. Too much money to part with. Im so thankful for my 175 hp 2 stroke yammy.
