The boat looks like a virgin to me. The stringers look factory and I can see the cabosil from the factory. Good thing you are re-doing it the way the transom looks if you go with a bracket like you said earlier in one of your posts. Get rid of all that foam it's unnecessary and adds weight to the boat and traps moisture. The stringers are foam filled and that provides enough flotation should you swamp which probably will never happen. Your gonna love that boat when it's all finished
