				In a typical offshore trip we run 8 miles to the pass then 25 miles offshore. In the V20 we would use all 60 gallons of fuel running 32 mph. In the 250 Sportsman we use about 40 gallons of fuel plus we run 43 mph..

With my 250 (225HP 1991 Yammie, my sig is out of date) I get a solid 2 MPG ant anything above idle. Confirmed by GPS and flowscan stuff.
 
So if I go out 25 miles I'm going to burn 25 gallons.
 
You have twin 150's and go 8 miles + 25 miles = 33 miles * 2 = 66 miles and burn 40 gallons =
