Well, got home from work today and decided to cut open the deck. Stringers are solid. Drilled a few holes closer to the bottom and the looked good. It might have been redone once before looks like. The problem with the deck was it was only glassed from the outside, with no mat at all. To make things worse, the bottom side was left untreated it was just plywood. So this would’ve been rotten in s few months had I not done this. Onto the deck this weekend. I will post pics once done!
