I have a Volvo Penta SX 3.0. With the boat sitting on the trailer and the outdrive down as far as it can go with about an inch clearence before hitting the ground the outdrive will "fall" down the remaining inch over the course of a week...

ideas?

Re: outdrive doesn't stay in position?

one of two things do this.either your trim cylderines or the trim pump.you can isolate the problem by supporting the drive in the up postion then by removing the two lines to the pump and capping them off.if the drive does not leak down then the valves in your pump are leaking buy.
