I was thinking that I could test to see if cylinders are leaking internally by trimming up, disconnecting the hydro lines from trim motor and capping them off. If the drive drops then the cylinders are leaking. Anyone know if this is possible? I want to see if I can isolate the cylinders to see if they're the reason that the Outdrive slowly drops down.
