Size of Dinghy Gas Tank

[Therapy]

I have a 8' inflatable with a 6hp 4-stroke.
The tank that came with the set up is the standard 6 gallon tank.
I certainly don't need six gallons of weight and space in the dink as I have run around "all day" on a gallon. I don't have a way of accurately measuring dink gas consumption either so I think a smaller 2-3 gallon tank would be more than enough.
Is there a reasonable 2-3 gallon tank out there?

Lots of 3 gallon tanks available.

right you are 2 1/2 - 3 gallon tank would be nice. otherwise gallons sitting to long will go bad. I put a moeller 33323-10 filter in line bolted to the transom and this helps quite a bit. I also now use as my primary an older 2 stroke shamefully but god it runs great.

yeah, a six-gallon tank makes no sense on your rig. I run a three-gallon tank on a 10' RIB with an 8hp four stroke. Plenty.

WHAT AN IDOT I AM!!!

I wrote 6 gallon and am an idot.

I have a 3 gallon that lasts way too long and takes up too much space.

Are there 1.5 gallon tanks?

Hmmmm

I just upgraded to a 9 gallon over a 6 gallon. Figured I'd like to have the extra capacity.
9.9 hp 2 stroke on a 10' RIB.

I've seen one that is U shaped the attaches to the transom so it't not just floating around, not sure where but I remember it being a bit pricey, not insane but up there.
