'83 merc 80hp, installed new power trim motor. The motor sounds to be working fine. However, the OB will not trim up or down. I ran the trim motor in short bursts trying to get some movement but have failed. I turned the release valve (knob under the motor and housing into hydro's block) counter clockwise and still can't get the OB to drop. Even tried a few short bursts on the trim motor with valve open and nothing. Air lock? How do i fix ?
