Re: 86 Yamaha won't trim up
Does the motor come on when you trim it up? I would unscrew the manual release valve and position the outboard in the full up postion and check the fluid. I think the screw will be on the stbd or port side perpindicular to the transom where the engine is mounted. It will be a flat/slotted screw driver head. Make sure this is screwed in all the way somewhat lightly.
