    Optimum speed

    Does anyone have an idea of at what is the optimum speed for gas mileage is on a f-12X? I would guess somewhere around 35 mph which is about 4200 rpms, but I have no clue as to what fuel consumption is at that speed or any other for that matter. With gas coming up on $4 a gallon this summer it would be good to know while cruising down the river or when running low and you need to get back to camp. Thanks for all of your help, Dolfan14862

    My best mileage is at almost 40 MPH GPS. I get 7 MPG just like my Daughter's 15F. They use almost the same amount of fuel, always.
