Fuel Tank Size

Does anyone (owners, Skiers Choice) know the tank size on a 1988 Mariah? I think 18 gallons, but not sure. Also, does 6 gallons an hours cruising sound right? Last question, what size tank could fit in the opening for the fuel tanks? Seems there is some room under my ski locker, wondering if the tank could be bigger.

Thanks

The tank on my '92 Mariah is 38 Gals. If you pull out the plastic tray in the rear storage compartment there should be a sticker on top of the tank that tell the capacity. Mine has one.
