Hello, I have a 1981 Sea Ray SRV 195 260hp. I can't get the sterndrive to move. It's a OMC 800 and when you press the button it just makes a winding noise. Nothing moves, I'm new to the boating world but I've worked on cars for years. Just needing any help possible. Pictures of loacation, how to's l, anything to help me get my boat on the water.
