Outdrive falling. No leak.

My port drive won’t stay tilted up. There’s no leak in the system so I assume it’s a bad valve in the trim pump. Anyone know if this is serviceable or if the whole pump needs to be replaced?

Maybe try to flush out the system and put in new fluid. Run it up and down a bunch of times as well, maybe it will clear out any debris holding up the valve.

Do our pumps have a manual release like outboards do? Maybe it needs to be tightened if it does?

Some googling suggests that there might be an issue with the seal on the reservoir that is letting air bubbles in.
