Hi! I have a 87 Mariner 1987 135 hp<br />The trim tilt pump has started to leak.<br />It seems to leak mostly when the motor is<br />in the down position (although occassionally when it is tilted all the way up too) Leaks<br />bad when motor is down, you can see fluid in the water. My question is this, any certain seals orings to change, or should I just change every seal? No work has ever been done on unit since new.

Yes it's the v-6 marathon model. It is visible in the water. Now the motor is fully tilted up and looks like it's leaking near the bottom part of the assembly, near the two trim cylinders and the tilt cylinder

I think you can get seal kit from merc for the cylinders. The o-rings for motor and pump were were hard to find, I now have source fro them.

Clanton,<br />Thanks for the help. What do you recommend?<br />Replacing all the seals? What's the contact info for your source for the parts?<br /><br />Many Thanks again
