I have a 1976 starcraft 18' rivited aluminum boat. It has a rotten transom. The rest of the boat appears fine. It is totally gutted so I can see everything. I am going to fabricate an all aluminum transom for the boat. I don't want any wood to rot. Should I even bother or should I scrap the boat. I don't even know if the rivits leak yet. I paid 500 for the boat with a 1977 70 hp rude. Running condition unknown.
