Yamaha Power Trim Repair/ Rebuild & How to Bleed

In this video we show how to repair a Yamaha power trim unit, Replace the O rings, Refill and bleed the system.
Cap tool: I now have this oneamzn.to/30hvjvU it fits 32mm* x 4mm (1.25” x .15”) pin spacing, I liked it because it came with replacement pins. I have not needed to replace them yet.

Thanks for the tip! I saved my neighbors fishing trip!

Nice video!i am about to do mine .it is a johnson tilt trim.my problem was I would put the motor in reverse and it would pop up out of the water.So,I boat the seal kit and am about to replace today.

[@ethanseltzer]

Nice video. Can you please point me to the video that discusses the no start, poor running fix?

[@cormacgj]

Have a Yamaha 140 two stroke three wire and issues with the Check Valve and Spring Missing. Do I need a new Check Valve or Trim Assembly. I also have an O Ring weeping. Great video 👍

[@keywasted289]

I would not use pliers to remove the piston. Any burrs or scratches put on it may cut the new seals/o-rings and leak. Otherwise, good video.

[@dirtydelta7]

As soon as I saw him pull the piston with pliers, I shook my head and killed the video smh . His next video shows you how to install an oversized turbo with a mallet.

[@kreigdernier9553]

ACTO Gunsyou can use pliers I used vice grips but i took an old leather glove cut the thumb off of it and used it as a cylinder condom before clamping down on it with the pliers

[@dirtydelta7]

I've done this twice to my VMAX and I use an old silicone oven mitt to grab the piston and pull on it. It works like a charm. Even easier before you start, put your engine on the stand and make sure the trim pistons are out as far as they can go before you start. You wont need any tools to get the piston out.

[@greatestskills7447]

Not much of a problem if you grab only the top of the piston that part does not normally run through the seal except for when you reinstall the cap. If you do bur it polish it with fine sand paper dont risk the new seal. Brass jaw pliers also work well but are hard to find. I like the old silicone oven mitt idea never tried that one.

Guys, knowledge alone doesn't make you a good mechanic. Knowledge and the right tools do. The spanner wrench he used is not the right tools for the job. Also, they stripped the cap when torquing the cap, not while removing it. The spanner wrench needed has 4 little knobs and looks like a Crow's foot that you use with a breaker bar or a ratchet. Also, they sell pliers with silicone tips or cannon plug pliers are excellent for that. Also, a $100 condiment bottle (ketchup are red and mustard are yellow) are excellent for filling up the reservoir. If you can't find the correct fluid, Dextron III is a good replacement for Yamaha power trims. My 150 power trim runs great with it. And actually the Yamaha manual indicated it can be used.

[@randytucker6841]

What about the release screw? At what point did you re-engage that? I assume it was prior to the rebuild?

[@deweypug]

Awesome tutorial!! Cheers to you!

[@frankvazquez0238]

What kind of oil did you use to refill it

[@sacem52]

I'm trying to replace the tilt/trim seals on my 1997 C60 2 stroke. I cannot find the part number for the o ring that is inside the trim cylinder cap. I'm able to locate all the other o rings such as the trim dust seal that is on the outside of the cap. Can you help out with a part number or any advice? The o ring I'm looking for isn't listed on any of the parts diagrams for my outboard. Thanks!

Thank you .. Your video saved the day !!

[@CrazitOStudiO]

Thanks for the video. It helps me a lot !!!!

[@jerrychf]

Thanks for your video. I have a yamaha 115 2 stroke which having issue about the tilt, I had a pump to fill the oil inside the tilt but it runs rough, sometimes when I run all the way up and it stuck at the top position, what I can do in that moment was using manual release valve to lower a little bit, and trim down and it works. I using a pump to pump oil into it until oil flood out the hole, but I had repeat the process about 3-4 times still getting problem with rough trim down and stuck at top position ... I had check the system didn't leak, because I stay the boat for overnight after wash and dry, I turn back another time and didn't had any oil I feel when I touch the trim and lower. Any suggestion?

Question: Evinrude 140 VRO... been sitting for 6yrs. Last time used was working great. Getting it ready, started with the tilt trim. Goes down immediately when I connect battery. Dismantled the switch thinking it was stuck. All 3 wires at the switch separated completely still when I connect the battery, the trim goes down immediately. Connected a new switch. Still goes down only and when pressed up, makes a clicking sound at the relays it has 2...switched out the relays, still goes only down. From the tilt motor there is only 2 wires coming out with ground. Directly connected battery to motor with green wire, goes down. Connected blue wire and it started to go up!!!! But when I reconnected all back, connected the battery and 😡 only goes down immediately without the switch being activated!! Please help

[@jbass34]

Very Helpful ..... Thanks

[@jimpipitone5371]

my 2003 Yamaha 90 horsepower oil level is very low and the tank is full and the engine won't rev up while viewing some of the videos on here I'm guessing it could be the fuel pump

[@jamienichols6277]

I put my cap back on my old dt150 suzuki and when the motor came down it blew out the seals? Now I'm nervous to add fluid to my new motor.

[@greatestskills7447]

yours might be a different year but I got them from a local yamaha dealer/repair shop.looked up the parts from www.yamahaonlineparts.com

[@dennisfrier3191]

Maybe if you used a hydraulic cylinder spanner wrench , and not a grinder wrench , you would not have to destroy your cylinder caps . just a thought ........

[@greatestskills7447]

cap was all ready partly striped out when i got it. check out the beginning off the video. At the time i used what i had . I agree though. I now have this one amzn.to/30hvjvU it fits 32mm* x 4mm (1.25” x .15”) pin spacing, I liked it because it came with replacement pins. I have not needed to replace them yet. i have another size too but this size seams to be the most common.

[@jonathanbonello596]

I have the same problem with my Honda BF50. Can someone inform me where I can buy same oil Seals for Honda? Most sellers I contacted wanted to sell me the whole cylinder which works out to be quite expensive.

[@bbnnkk1]

What happens if you strip that screw

[@devonsilkwood2073]

How did you bleed off the cylinders?

[@greatestskills7447]

Fill it up, put a drain pan under it, run it up an down a few times till the all the air works it self out top it off replace the plug.

[@devonsilkwood2073]

Greatestskills is there any way to bleed them without trimming it down. My motor will not trim down at all. I'm not sure what the problem is

[@greatestskills7447]

crack open the manual release screw if it wont go down then and cant be pushed down by pushing down on the lower unit something is binding where it pivots. if it goes down with the manual release open, fill it and bleed it probably low on fluid, if the motor only runs going up its something electrical.

[@willwillison3521]

What if there is water in your reservoir?

[@ronymorales3527]

Can someone tell if the big one in the middle is the same proses or diferrent thank you

[@russelldevane5434]

Pretty much the same.

[@jacobcrawford9058]

where do you bye the tool to take the caps off?

[@DanA-ix7ms]

***** Harbor Freight has these.

[@dennisfrier3191]

I'm sure you have learned by now that harbor freight does not have the correct wrench. He was using a grinder wrench , for changing disc on grinders, that is why he had to destroy his cap with a hacksaw and hammer .

[@tommycrandall1052]

[@Streetzzz]

i disconnected the lines from the tilt/trim now the the motor just spins . the two cylinders work but not the main one

[@greatestskills7447]

navigator is boss!you might need more fluid and need to bleed the air out. that is I am assumeing the main cyl was working before and not seized up.navigator is boss!

[@beachcheckin]

You didn't change the back up ring,,, when you changed the inside o ring..

[@zgambler1]

grabbed the ram with pliers also bad idea

[@jb0uchard]

Can someone please send me link for the tool used to take the cap off??

[@wazup3333]

Will Willison you can get that for 5$ at harbor freight but it wont work on mine. started bending the tool and cap wont budge, manual release wont budge either. plus the pins arent the best fitment and you can strip the holes

[@kreigdernier9553]

The actual tool is about 90 us...

[@wazup3333]

to much money for one time freaking wrench

[@kreigdernier9553]

wazup3333 i bought a 13 dollar gland nut wrench but the removable pins were too thick. I put them into the chuck of my cordless drill and turned them down on a bench grinder while taking measurements with calipers till this were the right dimensions.tried the cheap angle grinder tool but i bent them pretty quick on very tight.

[@wilhelmvo6399]

How do i replace the trim motor i have a pro 50 lg without pulling the whole motor off the boat?

[@kenmoses8]

Billy Vo did you ever get your answer? I took all 3 apart and replaced the motor. Now I have no idea if the top middle has a sequence for adding to the rest?

[@chrischudkosky5784]

Chris Chudkosky dude I’ve tried every damn Spanner Wrench keeps braking . Gonna try the chisel hammer trick

A honda mech told me they use ford ATF transmission fluid

[@joeshwetz5901]

You can use Dextron 1 or 2 type tranny fluid any higher say 3 and above has too many detergents which causes foaming and hinders the hydraulic process !!

[@rickgoodman1900]

I’m sorry I can’t tell what you are taking off and I don’t know how, so you aren’t helping and I missed the part how you got the motor to stay up

[@maxmax350]

So many mistakes in this vid.. Additionally to what's already been mentioned, you put the dustcap in the wrong way around. Also, the ram is severely pitted (see 6:04) so it'll start to leak again soon after this 'fix'

[@DREWGRANTHAM]

Holy cow can hardly hear you woth bird in background….

[@mikebatiuk630]

hydraulics 101 don't grab the rod with pliers... don't savage the cap with a chisel use the correct tools for the job
