OK, Trying to help out a friend I work with. He has a 17' Key west with a tank in the floor that leaks so he cant use it. The problem with fixing it is he cant get the thing out. The tank only has about 3/4" room on each side of the floor opening to pull it out, however, it was sealed into its space with what looks like the "Great stuff" insulating foam. Not enough room to cut the foam out. The only thing i can think of doing is cut up the tank after flushing it good and removing the pieces. Any suggestions?
