Amazed that boat's transom will take the weight and stress. I've seen videos from this guy where he's hung two and tree 25hps on that boat. Maybe he's reinforced it.
I only subscribe to two channels,your channel is one. Good informative videos. No nonsense BS. Keep them coming especially now we are getting into our boating season in the north east. Good job.
Great work and best tutorial.I bought a 2009 40 hp Yamaha 2 weeks ago.Got it cheap as someone hit a car and smashed the motor at 60 kph.Smashed the trim/tilt so I removed it off and will not use trim .happy to show pics.Thanks for again Regards Trevor in Australia
ThatBoatGuy I have a pontoon boat with Johnson 90hp 2 stroke. My problem is that three different boat mechanic can’t figure out why motor will throttle up with water phones on , but when I the boat is in water and motor is under a load will not. Starts right up and idles fine. Any thoughts?
@@robbiehopper4121 sounds like your stator or kill wire is shorting to ground somewhere. check and clean all ground connections. take the carbs off and make sure they are both clean, paying special attention to the low speed passages. then do a link n synch according to the factory service manual . i've fixed these issues many times. the problem now is its harder and harder to find a good 2 stroke mechanic.
Gday mate this is the same model i had in a 50hp it was on a chase boat up north and i had it shipped down , stripped the head of not to bad but looked like something had damaged the inside of the combustion chamber ,checked with a local mech he said nothing to worry about changed all the sacrificial anodes out and cleaned as much as i could up with a stainless wire wheel on my dremel put it all back together and ran like a top start first crank every time .
Afternoon 😎 just wanted to say thanks & I really enjoy the channel. I scored a nice Honda Shadow VT-700 in the same type of deal because of the huge difference in compression between The jugs. When I got home and pulled the head off the Bad jug I found out the exhaust valve was cracked. Got online and found a nice used head for like $60, then flipped the bike and made $500 😎
Great job. I’m with you on painting it, already into it might as well make it look as good as it runs. We’d make good neighbors, I can’t resist good deals and tinkering either haha.
Great job! It is impressive that you went as far as pulling the power head and repainting it to make it all match. I am so like that you went ahead and got into the carbs to make sure they were good . . . because you are right it was the best time to do it. Incredible job!
Your videos always help me with something I'm doing somehow your lucky you live in outboard heaven. It's hard to find good motors and boats to make money on here in NJ. I do a lot of work on smaller Johnson outboards and Yamaha's outboards are just fun to work on.
as I wrote in the previous comment, I bought the same engine. It fires up and works very well. Trim seals need to be replaced, I already have the part numbers from your movie. Greetings from Poland
Your just like me my freind,, love the Yamaha,, l work on many of them so easy and simple heaps of conferdens and skill with your tools,, you just get into it and fix what ever needs to be done,, any thing under 60 hp dose not get hammered like the big hp moters so not much there to fix ,, l have to say that the worst thing to do to an outboard is to not use it ,, so most of the ones you find have low hours witch makes it a great byeing and great for making a small profit , love watching your hands go to work,, can you go up in hp ,, they do get heavy to move ,,, enjoy watching you at work l never get sick of you,, well done ,, simmo
Great video. A little more detail on the how to side of the repair. This goes here. This lines up there. Identifying the parts as you remove them. I have worked on boats for years. Fiberglass, Gelcoat, floors, carpet. Never did any mechanic work except for basic service and winterizing. Seems like your pretty knowledgeable.
@@kevinpaiva6564 I agree but extra details put into his service has people coming back for more engines later or friends of those people... he has to be very well known for used engines and boats in his area alone. If you buy an engine from him you would know the kind of detail it went through before it came up for sale.. just my .02
My neighbor's dad had a Cape Horn 16 with that motor on it. We were running a small creek and his dad didn't know the water was full of cypress stumps. You guessed it- we hit a stump at about 25 mph. It completely stopped the boat and somehow threw the engine cover into the boat. No casualties though.
That Publix is down the road from my moms work , she’s working at the bay pines va and tells me that little inlet is full of fish. What I wanna do when I get my whaler redone is take the boat over to Angry peppers , which is right behind that Publix . They have boat access and awesome bbq
What most people don’t understand is that a transom rating is a safety rating mostly for speed. My 16’ has the same exact transom as my 18’. Both riveted hulls. The 16’ is rated at 75. The 18’ is rated at 115. Basically the same exact boats. One is just 2’ longer. I run a 115 on the 16’ and the transom doesn’t budge. Been running her hard for 11 years without a problem.
Also, I saw that same add while looking for power options for my project. Turns out my power is just fine and did not pursue the add. Nope wasn't the same add. My bad. I might have made the 3 hr drive from here for it though. Nice find.
Good job Eric i have an 06 90 Yamaha with 65hr on it i luv it did buy it new dont use it much unfortunately but every 2nd month i will run it for 5 or so minutes 🇦🇺
Amazing video and channel!!! Love how you go into detail fixing the boat and at the end we get to see it running out on the water!!! Love your channel dude
Maybe you could give me advice, I have a 90hp Mariner,runs good for half a day then loses power drasticcally,sounds like she is smothering. Cars been done as well as the feul pump. Idles great. When she loses power and you put it in neutral and rev it by hand, it revs good.
I'm cracking up over here.. can't believe you removed the powerhead to paint it.... but good for you! Here's my question. You removed the carbs and flywheel before removing the powerhead then during installation you installed the carbs and flywheel prior to installing the powerhead back on the motor??? A bit confused? Could you have removed the powerhead with flywheel and carbs still attached? I've never removed a powerhead before that's why I'm asking.
Another great video..... Question, the saltwater corrosion you have with the replacement part, 1) What do you use to get bolts off without breaking them, 2) Do you remove the saltwater buildup inside the heads when you can or just leave it be?
hi there very good video made me thinking to paint my Suzuki DF175 also. but i have noticed that the cut off lanyard is NOT attached to you be careful and stay save. thanks nice day
Yamaha are great motors, good engineering makes for easier rebuild. You do a great job of doing it keep it up! Looks like the boating world has slowed down, plenty of empty water along the coast. I am just south of you in Englewood, plenty of nice open water here too.
Are these boats rated for this power? Here in Germany everything tops out officially at 10 HP or 15 unless it's a huge heavy boat that will need the 30 HP or so it's rated for. But in the US everybody seems to be running huge motors on small boats.
Good job. Did you remember to use antiseize compound on every bolt so the next person who takes it apart to fix a head gasket doesn't get the dreaded snap snap snap ?
I have 2004 70hp Yamaha. Been having it go jnto limp mode numerous times and I think I finally figured out the issue. I believe the oil pump failed that drips oil into the carbs. Performed an oil pump delete. Planning on mixing 50:1. Do you have an experience with oil deletes? Any pearls of wisdom? It looks like in this video the oil system was not installed or it never came with one. Thanks for the video
Since you had the head off, why not put fresh, new rings on the pistons? Also, why not get the water channel(s) area in the head coated? (Zinc/other) When you/if you sync the carbs do you use a vacuum gauge? BTW your boat really seems to like that motor!🙂👍🏻
I'm mechanically inclined, just not outboard motor mechanically inclined. Your videos are great tutorials!!
Agreed,
You should give us an in-depth view or insite of that boat, how it manages to hold a 90 without completely tearing the transom off is amazing
Jack Kitchin lol it is amazing 😂
Just don't get out of the hole to fast
F=ma
He's put 3 yamaha 90s on that before
It's just a modified transom attachment with bolts. Usually they're online.
I couldn't help but be scared for your safety when I saw that 90 on the john boat. Super sweet deal for that motor. Great job!
Amazed that boat's transom will take the weight and stress. I've seen videos from this guy where he's hung two and tree 25hps on that boat. Maybe he's reinforced it.
He’s put twin 50’s on the back before! Check his channel for the video. It’s crazy!
Didn't even wear the deadmanscord.
wow man impressive how your competence makes you fearless just take the whole thing apart like it's nothin! Major knowledge-envy.
I'm still surprised how that sketchy jon boat is capable of taking a freaking 90 without breaking into pieces ..
Murica
Looks fine to me! As long as it's rated for it.
@@fishingismydrug1 I don't believe that boat is rated for 90
@@Daandeslions It might not be.
Me Too LoL

Thanks for all this video keep up I love all your video
Your videos and tutorials have gone up incredibly in quality! Keep it up!
So someone replaced the head gasket but didn’t notice the hole in the head. Or is it not obvious with the gasket they replaced
I guess they did not see the hole in the head. I almost didn't see it also
@@ThatBoatGuy How the hell did the hole even get there?

Can you do a more in depth “tutorial” on removing the power head?
Attention to detail. That’s what makes your videos awesome!

That was awesome! That was a great job on that 90hp Yamaha...thanks for sharing.
Good job, great motor. Love 3 cylinder yamaha s. Have a 40hp, would like to upgrade to 70 someday. Dont forget the kill switch lanyard
That's sick fast!.. i got an 85hp yamaha.. thinking about tuning the engine to 100hp with a kit i saw online..
The boat i got is a Narwal 520
Very cool...simple when there's no bs'n around.
Tape the key to the shaft... or somewhere where you dont forget where you put it for safety !!
Had the same problem before the summer few years back, hats off to ya you know your stuff👌 you were definitely around engines as young lad!

Nope wasn't the same add. My bad. I might have made the 3 hr drive from here for it though. Nice find.
Nice job. I like how you show testing every motor that you repair on a boat.
That was a great deal for the money you have in it. What a work horse of an engine
Good job Eric i have an 06 90 Yamaha with 65hr on it i luv it did buy it new dont use it much unfortunately but every 2nd month i will run it for 5 or so minutes 🇦🇺
Where is the best place to find rebuilt powerheads? Like, is there a jasper for outboards?
Amazing video and channel!!! Love how you go into detail fixing the boat and at the end we get to see it running out on the water!!! Love your channel dude
Great. I just change impeller my Yahama 30 autolube. Runnin goog. You have great videos. Greetings from Finland
Love your spirit and skills. Thank you
Maybe you could give me advice, I have a 90hp Mariner,runs good for half a day then loses power drasticcally,sounds like she is smothering. Cars been done as well as the feul pump. Idles great. When she loses power and you put it in neutral and rev it by hand, it revs good.
The lanyard should be on your wrist Captain. Especially in a set up with you hand in contact with the engine.
2:11 oooh no don’t touch me there. 1 second later...
Water outlet stream gets stronger 😂😂😂
That motor is massive on that little Jon boat I love it
Those Yamaha enduro are bullet proof. The Fisher folks from my island will never go out unless it's an enduro on the stern.
I could watch this guy repair motors ALL day. MORE!
Man having the torque specs and on the pattern is a no brainier. Wish cars did this.
We stick the flywheel key with flywheel magnet to keep it safe. Good video.
Nice rebuild man , good to see a cast away get tuned up like that and work that smooth
Well done.. i wish i knew all about the mechanics of an outboard and how to fix them.
If only this man could do travel work. Great video!
I’m excited I just picked up a 75HP Yamaha can’t wait to see it run
What a talent! You could make a living with these things and your knowledge!
I'm cracking up over here.. can't believe you removed the powerhead to paint it.... but good for you! Here's my question. You removed the carbs and flywheel before removing the powerhead then during installation you installed the carbs and flywheel prior to installing the powerhead back on the motor??? A bit confused?

You made this Engine Like NEW Again Sweet
Saving the planet, one outboard at a time!
What style motor layout would you call it. Its not standard OHV or standard Pushrod on cars. Would this be sismilar to a flat head?
Another great video..... Question, the saltwater corrosion you have with the replacement part, 1) What do you use to get bolts off without breaking them, 2) Do you remove the saltwater buildup inside the heads when you can or just leave it be?
You legit live right by me!!! That’s my publix lol
Did you have carbs wide open when checking compression?
Enjoy your vids. No boat, no motor, no mechanical ability. Still the vids are enjoyable. Thanks.
Do you sell the motors you fix up because I’m looking for a 90hp Yamaha tiller
Enjoy your videos ill watch them multiple times to gain the knowledge that you have thanks a million
Question please? Did you start the motor directly through the starter and not through the solenoid?
It takes a lot to kill those Yamaha outboards. From years of watching your channel I am convinced that these motors are built like tanks.
Absolutely buddy. I got the same 90hp on a 16ft bass boat and it's bullet proof. Turn key all day long. The best outboards Yamaha ever made
hi there very good video made me thinking to paint my Suzuki DF175 also. but i have noticed that the cut off lanyard is NOT attached to you be careful and stay save. thanks nice day
A 90hp on a 16' boat is a good power match up! Nice job Boat guy 👍

Thanks a lot for sharing your experiences with us.
That big ass motor on that boat.....too funny.
Hey man I just want to say that I'm a beginner boater and you make it look so easy. Your videos are very entertaining.
Are these boats rated for this power? Here in Germany everything tops out officially at 10 HP or 15 unless it's a huge heavy boat that will need the 30 HP or so it's rated for. But in the US everybody seems to be running huge motors on small boats.
Also wondering what harbor waterway you're running around? About a hundred percent sure it's Florida West coast.
90 hp with Tillerarm.........crazy!!!!
Cool !
Thank for the tips. That boat and motor look like a fun combination
Another question. I rebuilt my carbs and now it idles at higher than before and its because the carbs don't close all the way.
ThatBoatGuy is awesome! Very good videos. Makes me feel like I can do this myself!
Great to see a perfectionist and an expert at work! Alan Northern Ireland 👍
Nice video. Buying a 90 tomorrow. What boat ramp was that?
What is that foam stuff you are using ? That looks like it will do its job!
Good job. Did you remember to use antiseize compound on every bolt so the next person who takes it apart to fix a head gasket doesn't get the dreaded snap snap snap ?

Dang you skipped the one thing I was trying to find. Did you put grease or anything on the threads of your powerhead bolts?
Since you had the head off, why not put fresh, new rings on the pistons? Also, why not get the water channel(s) area in the head coated? (Zinc/other)
When you/if you sync the carbs do you use a vacuum gauge?
BTW your boat really seems to like that motor!🙂👍🏻
You are the Best, Your videos are great tutorials!!
When you started it with the jumper cables, did you put them both on the starter or was one on the solenoid?
I would think at some point, you would re-paint that jon-boat. Lol
Lol I guess he cares more about his motor
you do absolutely amazing work. I loved your Airboat project !!! Kee them coming.
