Hello,<br />this is my first time posting. I have a 93 crownline with a 4.3L mercruiser and an alpha one lower unit. When I turn to the stops (usually when manuvering from the dock, launch etc,) I hear a clacking noise, not loud, but I dont know if this is normal. This is the second year Ive had this boat, and my previous boats have been outboards. The noise also occurs when I am turning when the motor is not all the way down such as turning in shallow water. The onset of the noise will be much sooner when the motor is up than when it is down. When the motor is down I have to go to the stops to get the noise to occur, but when the motor is up it will start clacking much sooner in the turn.
