'93 Yamaha Pro60 trim/tilt leakdown

[PRO-V]

Sometimes, mostly during cooler weather, the trim/tilt will fade down slowly. Occasionally in warm weather too. It will work great but sometimes I get under way and it starts dropping. I keep trimming it up on the run and finally it will hold. Same thing happens when I trailer sometimes. It's tilted all the way up and and won't stay there. Our local dealer isn't too sharp so no answers there. Any ideas? Thanks.

hello<br /> could be a number of things. a main valve leak, a piston oring not sealing or a leaking or loose manual relese valve.<br /> the main valves are testable when removed. the orings are replacable and so is the release valve.<br /> good luck and keep posting

Could it also be low hydrolic oil? Just a thought.

Thanks for the reply guys. A little cold up here yet so will have to wait a couple weeks to tear into it. Definitely not low fluid though, that was the first thing I checked.
