I have just acquired a 1970 starcraft starchief. it needs some work. Most import is the transom is rotted and needs replaced. once I get the moter of it and remoe all the screws will te old trasom lift out? this is mostly an aluminum boat. I hove other things it needs like new deck what is left of it iss delaminated plywood. I am concerned about the motor and the transom then rest I consider cosmetic. what is the best thing to replace the transom with? more wood or is there a better product?
