The trim just stopped working while we were out boating last week. Our friend bled the fluid out of the hydrolic line and took the motor apart. He found that the brushes were shot. We have been calling around to replace the brushes, O rings and seals - parts would have to be ordered and would take a week or so. We need to use the boat this weekend and are looking for a solution until we can fix the trim properly. Is it possible to replace the fluid (how do you do that?) and use the boat by manually lifting and lowering the engine?
