Bought a '93 Bravo I/O and the trim gauge does not work. Its pegged up when ignition is off and pegs down when ignition is on, regardless if drive is up or down. Moving the drive up and down does not effect what the gauge does. I do know the arm on the sending unit is hitting the drive and goes up and down as drive does. Does anyone know how I can troubleshoot the problem to see if the sending unit is bad, or gauge is possibly bad?
