I have a 15/42 Duracraft 1985 model. I have no pictures at the moment but I'm trying to restore the boat. I have everything off of it including the old wood transom. I have noticed some pitting and corrosion mainly around the bolt holes that held the transom to the boat. Upon flipping my boat over I have also found pitting and corrosion on the bottom where the boat sat on the bunk boards. Mainly around the rivets. How do I stop the corrosion and what is the best way to repair it?? ANY good information will be greatly appreciated. This boat was used in salt water before I bought it. I will only be using it in fresh water.
