IF I am remembering right your trim pump is separate from the motor and is probably in the bilge area. There is not a check valve but there is a manual bleed valve that will lower your engine, check to see if it has loosened up. It just looks like a thick black screw and the head of it is about 1/4" thick.
I tryed to tighten it but it does the same.After looking around I'm thinking it the pilot valve but I just can't enough info to take it apart and get parts.HELP PLEASE
Your tilt and trim cylinders probably need to be re-built. It sounds like they are by-passing.
