    250 pro xs, won't stay trimmed up.

    out of the water and trimmed up all the way, it will be down all the way by morning if left with out motor support in place. Should I be worried? Boat is on the dock hoist so I can't put in the engine supporter. I don't seem to have a problem while running and adjusting trim. TY

    Is it trimming down or bleeding down? If it is trimming down, then it is most likely a bad trim relay. If it is bleeding down, then you either have air in the system or a leak. If air can get in, so can water. Get it fixed. Also, check the trim pressure relief screw and trim reservoir cap to make sure they are tight. There is also a gasket on the reservoir cap that could be bad.
