that would have been perfect but I measured and I will need the low profile type. The clearance under my seat is only 12". I do not have the room in this boat for a larger tank. I do thank you anyways.here's the one I got.. Size: 20-3/8" L x 13-3/4" W x 14-3/4" H with cap..It's in good shape. I would let it go for 30 it has an OMC hookup.
