Scot,

My 2cylinder Universal (18 hp approx) does 6 knots an hour on a
little
over 1 Quart. At 4/5 knots, if not bucking a tide or a stiff
hedwind,
I'd say you'd need about about 26 quarts or 4 Gals.

What is your motoring range for your boat with the 12 Gal tank?

Don't know Thom, that's why I'm asking here i filled up last time out
and took on almost 5 gallons, that was for the season. I don't motor
much, and I plan on sailing, but I want to have a back up, just in
case.
