Does anyone know of a fuel tank that will fit nicely in the belly of my 18' Super sport?

I will be using the boat this summer so prefer to track a tank down prior to ripping up the floor.

Any help would be appreciated.

Thank you!

I would love to have a belly tank in my 18' Offshore. It frees up room for fishing by moving the above deck tank away from the transom.

I would also relocate my batteries. This would give me access on either side of the doghouse all the way to the transom. A fisherman's dream.

Someone on this forum did it on an 18' I believe. The raised the floor up to fit it underneath I think. I don't know if I would go to that length though.

I was able to find a Moeller Poly Tank discontinued that fit my boat from Great Lakes Skipper Marine.. You can also have a custom made alum tank, a little more money but if you cant find the right dimensions.

I've also seen some listed on CL, and also call some Alum Salvage yards even boat yards, there' out there.. just need a little googling.

I think cabelas has a few poly v tanks, not sure if the size will work for you.
I would also like a poly v tank in the belly of my Cheiftain, 45 gallon one for me. Good luck. I hopefully do not have to remove my floor for many many years so I am going to make do with my twin 16 gallon tanks that are above the floor.
