I have a 1984 Champion (mean 16, 150 Johnson) with what appears to be a weakening transom. (1) Can the transom be repaired? and (2) is there product(s) out there that work better than others. There is a product line referred to as "The Rot Doctor" and wondering if anyone has heard of it or used it. I have contacted the Champion factory via email to see if they still do these repairs. I have not heard from them yet. Luv my boat and do not want to loose it.
