I recently purchased a 1989 bayliner capri 1 owner who took excellent care of the boat. It had been in storage for about 2 years. However, there is no reverse. I took it to a local service center and was told it needed a new lower unit. I bought a rebuilt unit and installed it according to the force service manual and i still have no reverse. As i was testing the unit, a buzzer sounded from underneath the dash. Each time you turn the ignition it buzzes! Any suggestions would be greatly appreciated.
