Mine did that last year, get a motor hoist or something to lift the leg up..as soon as you can take out the top plug on the ram---take it out !....Once up fill to the top and make sure it moves up and down and top off again............( . )( . )............comprenda

Does the trim pump even run? Could be something simple like a solenoid. The pump may be in the boat or between the mount plates. If between the plates, the relief is on the rh side. If in the boat, it will be on the resevoir. Those solenoids have real small wiring and had a problem breaking. (at least mine did) Napa should have a marine listing for the solenoid you'll have to go into the store and ask. The internet site won't let you in to browse.
With the relief valve open I was able to tilt the motor while my 16 year old shut the relief valve off. Don't think he will need a engine hoist, but might save the old back. Gary
