I have a 1991 Yamaha 90 on my Montauk and I noticed that there is a little bit of oil dripping out around the base of the power trim/tilt unit where the rod comes out to push the engine up.

Is this normal or do I have to replace the seals.

Do you think I can wait a while?

Is this a do it yourself job.

I have this problem too on a 1989 225 Evinrude. I asked for an estimate on it--it's most likely not a home-do job. The tilt cylinder is the big one in the center.

-tilt motor all the way up
-lock in place
-take out trim system
-unscrew cylinder housing, may need heat if salt water
-replace seal.
Its pretty easy but may need special tool for unscrewing top of cylinder.

dude, add a couple of oz. of "automatic transmission fluid conditioner" (from your local auto parts store) and run T&T full cycle (up and down) a few times. The conditioner will swell the O-rings and seals and make them more plyable and hopefully will fix the leak!!!! It takes a few days for results, however. Happy Whalin'... Clark... Spruce Creek Navy
