Mercury tilt problem

spinfreak OK...here's another question that someone might be able to help with.
On my starcraft, I have a 1984 150 hp Mercury Blackmax. The tilt works fine, except for when I leave the motor tilted up. After being tilted up, it starts to creep down slowly. It takes probably 20-30 minutes before it goes all the way down. There's no fluid leaking out or any other problems that I could see.

It's no big deal, as it doesn't cause any problems for me. But I just wanted to find out about it. Is the problem something that I could fix easily, or would I have to have a mechanic fix it? If I can't fix it myself, would I be able to leave it the way it is, since it doesn't cause any problems for me, or will it cause further damage in the future?
~thanks~

tajones I think there are some check valves in the trim that are probably leaking by. I don't know how handy you are but it will require taking the trim unit apart to fix it. It will probably get worse as time goes by. 2002-03-08
