Default fuel "economy"

just curious to see what everyone's getting as far as fuel "economy" in their boat/engine setup...twin 6 cyl. outboards on offshore boats usually get between 1-2 mpg at cruising speeds, how does this compare with your boat/engine setup? obviously the really radical engines will be less fuel eficient...I am wondering about the usual "stock" setups''....just curious in these "gas pricing" days

Single 454 Mag MPI, 24 Superboat, I think I am getting around 4-5 MPG. I average around 10 gallons per hour at an average of 50 MPH. Not Bad!

i tracked mine with GPS distances most of the summer and compared it to fuel used and found i am getting about 1.25 MPG. i am running a pair of stock 260 small blocks in a 26 foot scorpion. i could probably do better but i run them just about WOT all the time (hey they're small blocks . . cant hurt em )
