92 Mariner trim repair questions

[BJM]

I have given up on repairing it myself. I have replaced every O ring and check ball but the system still leaks down too fast for the pump to keep up under drive. I have narrowed the problem down to the actual pump, the motor and cylinder are fine.<br /><br />The local marinas seem unwilling to look at it. What are my choices? Mercury will not sell a pump anymore, just a complete assembly. Would a local hydraulics place be able to handle this sort of thing? It just a small hydraulics system after all.<br /><br />What about the aftermarket, I can find lots of motors but nobody selling pumps.<br /><br />TIA

BJM,<br /> Do you see any external leaking or oil(wetness) on the outside of the unit anywhere?Has corrosion eaten it's way through the trim assembly causing a leak? Post back.

Re: 92 Mariner trim repair questions

There is very little corrosion on the unit at all. I made a block off plate for the cylinder after removing the pump assy. The cylinder holds pressure fine, I couldn't make the engine sag even after hanging off it.<br /><br />With the pump back on and the reservoir off, fluid pours back up out of one of the pump orifices when I push on the motor. I have changed every internal part I could but no change at all.
