Most marinas on the lake have fuel. As has been said, if you keep off the hammer, you can get more distance. I ran from the Moors about 20 miles south and back, two days in a row with an 06 CougarFTD/225 Opti. I ran about 40-45mph. I used almost all of a 26 gallon tank. Plus a small part of the other 26 gallon tank. Id make a guess and say I used 30+ or – gallons.
