I have a 1990 Capri with a Force 90 motor. Got it running great thanks to Frank (where ever you are up there) and Jerry Jerry. Lately, when I tilt my motor up (It tilts up and down and trims just fine by the way) it will slowly start to drift back down on its own. Basic Hydraulics 101 tells me that the culprit is likely the tilt actuator piston seal is starting to wear out and fluid from the extend side of the piston is leaking past the seal and into the retract side of the piston. Before I order any seals (they are dirt cheap compared to everything else) I know there are some relief valves built into the piston that are there to allow the lower end to come up in case the leg of your motor hits an object (thereby saving your motor and your transom). Do these relief valves go bad often? Could there be something in the pump of valve unit causing this?
