Anyone know places in the Ottawa area that repair/rebuild marine hydraulics??
I'd like to have the cylinder and manifold of my power trim system serviced.
Mainly just replace all the O-rings in them, I think one is damaged somewhere in
there but I'm not about to open up that can o' worms myself.
Too many small parts plus not enough patience plus failing eyesight:
equals: frustration/cursing and probably completely ruined power trim system.
The cylinder is probably OK as is (no leak-down or other obvious problems), but I
think there may be a faulty O-ring in the manifold (valve body?) because on
occasion the motor will stick in the full 'trim-in' position and I have to reef on
the lower unit while someone operates the 'trim-up' switch until it catches
and then it'll work fine for a while but always ends up sticking 'down' again.

Hmmm. Almost sounds more like an electrical contact issue rather than a hydraulic one. Just a thought. Cheers

Not electrical, trim motor & pump operate as expected when switch is engaged,
just doesn't move outboard until I apply upward force to bottom end.
Thanx for the input though!

I'm not that familiar with boat trim systems but is there not some sort of switch that shuts down power when both ends of movement are reached? Or a solenoid? Or I guess there's maybe a pressure relief valve for that purpose. Or maybe you are low on fluid, which would mean a seal somewhere has leaked.

Here's a thread with lots of ideas you could check out yourself. http://www.marineengine.com/boat-forum/ ... p-position

Good luck with it. Cheers
