Trim pump problem?

I have a Bravo on a HP500 EFI that when I'm running the trim slowly bleeds down,or when it sits on the trailer ,within 24 hrs. it will be trimmed all the way down.Other than that it seems to work fine. I checked all the fittings for leaks.I never need to add oil so I know it's not leaking.Anyone have any ideas besides just buying a new trim pump.
Thanks,Guy

You have leaking internal o-rings,or it could be the trim pump check valves not holding.

It is the check valves inside the trim pump.
Been there had that problem.

How do you fix a "check valve leaking" problem?

If its ever had water in the pump you are screwed. You have two choices; either replace the pump valve assembly or just buy a complete pump assembly. OR just call Doller Offshore Marine @ 954.237.0332

Can't the valves be "repaired"?
