My 1980 Hunter 30 rudder shaft has slipped and left me with two problems. The first is holding the rudder shaft up in place. Its down about 2 inches, I can push it back but it slips down again. The second problem is that by slipping down, the bottom of the skeg that holds the bottom bushing broke. I was surprised to find the skeg hollow! I'm thinking a brass strap with screws into the skeg wrapped around the bottom along with fiberglass or ???HELP!!!!!!!
