I have a catalog from starcraft from 1980 and it shows the 22 footer has a 50 gallon tank.I have an older 18 foot starcraft center console and have fished it on the north shore for many years.Can't help with fuel consumption as I only have a 65HP on mine.

Is that gallons per hour or should it be miles per gallon?1.5 gph at full seems low

dallen, both tempo and todd make permanent poly tanks that can be installed permanently under a floor.Might give the nod to tempo.Your 21 footer is much different than the 22 footer.I am buying a 22 mariner and it makes my present 18 mariner look tiny. 21 is rated to 150HP and 22 is rated for 240HP. I wouldnt want to ride in one with max HP on it but it would fly!

dallenx-todd is sold through west marine.That 7 1/2 inch height is tough to fit.West shows an aluminum 18 gallon that is only 7 inches high for $185. What condition was the floor of your boat?Was it marine plywood with vinyl over it and was it screwed down or riveted?

dallenx-looked in cabelas catalog and moeller makes a poly tank,25 gallons,model 950 that looks good.18W x 47L x7.5H for $120 plus install kit and holddowns .

Tin boat forum sounds like a good idea.I think you either love them or hate them but it seems everyone either owns,fished from, or had a 12 foot tin boat at some point in time! Can't beat them for knocking around the rocks.
