I am restoring a Starcraft boat with a aluminum hull. I've replaced the floor, transom and after sanding notice some small holes at the bottom of the transom, from some mountings. Have no way of welding, what would be a good way to plug the holes? Can any one tell me what year is my boat? I have a Starcraft Starchief 18 ft serial 989453# is on the plate mounted on the inside.
