I have a 1994 Jon boat with a 50hp Johnson on it. I just bought it and everything was working good on it until i noticed the tilt was leaking down. I have already drained the fluid out of it and filled it back up. I have done everything I can think of to bleed the air out and it still will not trim up. The trim motor runs just fine and it trims down but it will start ti trim up but stops. can anyone help me with this.
