Yamaha 90hp Outboard Trim Seal Replacement DIY

[@matthewsmead9622]

To all the people who have leaking trim seals and think this video is showing you how stop your leak with the seal he replaced, it's not. He only replaced the dust seal, the seal that holds the trim fluid and pressure is down below the dust seal inside the cap and he never replaced it and it's much more important than the seal he shows in the video. Make sure you buy ALL the seals and replace them or you're wasting your time like this guy just did.

[@Fireship1]

I used your pipe trick today to loosen my caps on my Yamaha 150. Worked like a charm! Thanks for all of the great tips and videos Eric. I’m glad I found your channel!

[@johnnnyg100]

Me too the tool kept slipping out, I couldn't keep it from popping out. Put a pipe on like TheBoatGuy suggested and it took some extra strength but the cap spun without slipping! Thanks!!

[@tyyoung3698]

I love this video, so much. There have to be at least two dozen others out there, all with (I'm sure) pluses and minuses, but you made this task so easy to understand and I'm fully confident now that I can do this repair myself. Thank you!

[@daveperson1722]

This is EXACTLY what I needed to watch. Currently doing this exact job. Good descriptions and you made it look easy. Great job bro 😎

[@keywasted289]

Thank you for the very informative video. With your help, I replaced the seal and O-rings for my trim/tilt today on my Yamaha F250. I used your pipe trick as my caps were on extremely tight. My caps had a retainer clip in a groove I had to remove first. Thanks again.

[@amilcarfaleroblanco9575]

The motor you sold me is running like charm eric ,was a pleasure meeting you !!! yamaha 115 4 stroke. thank you for share

[@triggered1953]

The top seal is just a static wiper seal the oil is bypassing on the piston seal. If there was any pressure on that seal it would just pop out.

[@carlosiacona7806]

Great video, now I have already changed the seals, thanks

[@darrellsmith5395]

I wished you were u here helping me

[@billypurifoy640]

Yes you did a great job 👍 on The video easy to follow Thanks for all the part numbers on the seals

[@Daniel-pz4wm]

Nice 👍 even though it's old it's still very helpful🤓 makes me feel like I'm a you tube marine mechanic thanks to you🤠👍

[@ssteph1565]

Great vid Eric. I just replaced my trim seals ,,watched this before,,getting out the old seals from the caps would have been a challenge if I didn't see your vid, thx.

[@cmmuskiet6998]

Since you replace the cap seals, why did you not replace the piston seals on the rod as well?

[@Colinpark]

Excellent video, great camera work, excellent commentary , nice and clear and the tool link is a nice touch.

[@MrRainbowrooster]

Just ordered that tool a couple of days ago, looking forward to using it. My system is different, but the principal is the same. Thanks for the video...

[@TCross-xq4kc]

What size tool did you wind up getting? I see different sizes. Thanks

[@amclips2995]

Thank you! That pipe trick saved me pn my -96 70hp 6h3/6h1 combo. Thanks!

[@drewdavies1872]

How do I know when I have to service my trim tabs?

[@Cys62]

Good info tx

[@ykb946]

Thanks!

[@ermannodibenedetto3064]

Great job.....ciao

[@jayboogie27]

Thanks for the video! I successfully changed my seals out this morning.

[@russudvp]

Did you change out the middle one?

[@jayboogie27]

@@russudvp Negative. However, I now at least have proper pin/spanner wrench if I need to get in there.

[@russudvp]

@@jayboogie27 how do I send you a picture of what I'm trying to do. I'm stumped.

[@garrettfaircloth4486]

Have you ever done a video on servicing / seal replacement for the tilt cylinder on the yamaha 90 2 stroke? Getting ready to tackle that soon. Thx.

[@drewdavies1872]

I am working on mine right now. The the Trim side of the project was easy. I cannot figure out how to get the large trim ram fixed. I can’t figure out how to take apart the sub assembly, to put in new seals, and stop the leak. Any luck?

[@luism.raposo5138]

You look so much like my Sone. Handsome man. Thanks for the info on those seals. I have to replace mine soon. Thank you. I subscribed to your channel.

[@BillSmith-ut5li]

Place Motor so the fill hole is 90 degrees vertical to horizontal line. Remove fill hole plug fill until overflow. Install fill hole plug Cycle System several times. return motor to Vertical position remove fill hole plug check fluid level top off as needed. Apply small amount of thread lock to plug install fill hole plug do not over tighten

[@chrissmollen3190]

I have a 2013 Yamaha F70 4 stroke with a single ram tilt that is leaking badly. My cap does not have holes on it. Could I send a picture to get your opinion on how to remove?

[@Sheerkon]

Just found your channel. Love it! Please keep at it. You videos are so helpful. Thanks

[@Jubi316]

I need some parts for a 1995 Yamaha 75hp , 2 stroke . You have any parts for one I’m located in Davenport, Florida

[@captaindedo]

Thank you very much! Easy and very well explained!

[@a.h.boston9050]

THANKS ..

[@crispernator]

Gday mate i know this is an old video but i have an 90 40hp that has the same trim and tilt system on it this is invaluable information for me as mine is leaking too , those trim spanners are about 80.00 here in aus . Now i know what model to look at as none of the 40hp have this trim system (maybe of another motor) i will be able to get the parts i need to fix it , the trim motor is really sad covered in rust but still works so there is another 400.00 but with the cost of a new motor at around 8000.00 im gonna try to keep this one going .

[@sparky7146]

Nice video. Always good information on this channel. Thanks.

[@jaberaljalahmah2061]

👍👍

[@tyyoung3698]

One other question -- I didn't see a video on the process for swapping out a tilt/trim *motor* on your site. Or is that such a trivial matter that you didn't need to create one?

[@graemegladman]

Thank you very much. Great clear precise video.

[@Texcajun06]

Love this video. Any chance you could mention a part number for that spanner tool you used?

[@jerrywatts3784]

Very informative video thanks

[@tazmun]

I surely don't know for sure but most hydraulic systems are designed to measure the fluid in the reservoir when all hydraulic cylinders are compressed. It seems possible the way you're doing it you could easily get too much in the system? Of course access on the system you're working on would be a real pain if that motor was all the way down so possibly you're doing it correctly and it is designed that way?

[@The.Norwegian]

The procedure is to tilt the motor all the way up and then fill up the reservoir until the oil spills out, then run the engine all the way up and down a couple times and check again.

[@RichaRat]

The caps don't have to be super tight, just a little past snug. The oring and the seal are the seal. Also don't put teflon tape on the threads.

[@DanielSuran]

I love your videos man!! Very informative and interesting. I have searched the tube for videos describing a timing belt change. Preferably on a four stroke Yamaha outboard but I can’t find any. Can you please make one when you get at opportunity?? /Daniel from Växjö Sweden

[@jesteronetime]

great video bloke.

[@smirnoff56]

Appreciate the trim seal replacement video & link to the trim tool - thanks Eric!

[@psi23k]

Search ebay, tilt seal tool. Should come up, including the one he used. About $100aud

[@ErikLangnes59]

can you use thoose rings and seals on a yamaha around 2000 model trim too

[@tellerx1]

That info on the tool would be appreciated

[@iain1969]

What a fantastic video. Thank you.

[@Bushgator]

so I would have to jack up the trailer that my boat is on to get the canister that holds the fluid in to get it level? also I noticed you didn't mention the longer rod in the rear of the ones you replaced the seals on, do we need to change that one as well? Thanks

[@samtate1260]

I have a Evinrude 84 can I put dot 3 brake fluid in it I use it on my hydraulic jack

[@samtate1260]

@assassinlexx yeah I called The marina and they said they use power steering fluid if it’s just because it’s little low also herd Marvel mystery oil is good to from a guy working on outbords his whole life

Been subscribed and watching the. Past year or so nice work on the. Videos im a 17yr marine service tech You are Wrong about the oil link rod- if it falls off the spring on the arm of the oil pump automatically goes to full rich.

[@ThatBoatGuy]

I just now went into my garage and all 5 oil pumps on my 40's and 50hp 2 stroke stayed in one place including my 60hp. The 90hp 2 stroke did work properly. It went full rich. They should of put a stronger spring in my opinion.
