50gallons on a 20 cc with a fresh 140 Zuke would be Grrreat. If I were buying a 20 I'd be stoked to see such a package. :cool:

You might want to look at poly tanks. 50gal is about the biggest I could find when I did my restore. Pushed it as far forward as I could. The back of the new tank is where the front of the old one was. I am runnin a 150 4stroke yammy.
I have taken the boat 60 miles offshore trolled half the day came inshore a little bottom fished and back home on a tank of gas. Basically I can get about 200 miles out of a tank.
