Just purchased a 1988 13 foot Hobie Power Skiff, this is my first project boat so learning along the way The boat had wet foam inside that was securing the gas tank, I tore it all out including the tank and sitting on the bottom was this hard black almost like peanut brittle stuff and smelled of gas. I took a putty knife and hammer and started chipping away at it. My concern now is that it has gone into the drain holes of the bilge and hardened and possibly into a spot in the boat I can’t see or access without taking the lid/deck off or cutting a hole in the deck. I am opposed to cutting a hole because of all the other holes in the deck including the giant one for the gas tank. Jas anyone ever had this happen or seen this before?
