1997 Lowe, all aluminum floor over the tank as well. I would have to cut the floor open to access the entire tank, it can be done I guess. I'll have to start looking for a new tank. I have used both types of gas, and owned the boat since 98, added who knows how many additives over the years....any one know a good deal on tanks, a guess at 60" x 20" x 8" Sent from my iPhone using Lake Ontario United
