You guy's are probably getting tired of me by now, but... I'm looking at a 17' Thundercraft with a 150HP 6 cyl. Johnson O/B. The issue is (beside being out of style, interior is way out of style,but in great shape) there is a 8" crack in the stern to the right of where the motor bolts on. The ad reads, "Crack in fiberglass from being backed into". I know everyone will respond with " just walk away & go buy a new boat" I can't do that. Is this type of damage repairable? Everything else on the boat is in perfect condition & I think I can get it very cheap with a nice trailer. I know everybody looks down on repairing things like this, but has anyone done this type of repair? How did it hold up? Thanks for feed back good or bad.......
