one of the bravo 1 drives on my new boat doesn't stay up but gradually goes down over time

it would drop a 1/4 of the total trim over night

not sure if it does it at all settings or not

looks as though there is no leak and the oil reservoir seems to be where it should be (same as the other one)

what would be the best place to start
what type of oil is this

Shea you have a valve leaking down, could be in the piston but more likely in the pumps valve body. Almost every time I have pulled one apart all the guts were fine, what I found was a tiny fleck of junk under one of the balls. It is pretty simple to take apart even if you are not handy, the trick today is to keep your digital camera handy and shoot pic's as you take it apart. Phil
