I have the same questions about the Mileage on the 150 four strokes. I am planning on repowering and I am leaning towards the Yamaha. Does anyone out there have an f-150 and if so what is the miles per gallon and the miles per hour? I pieced my 1975 V-20 together and used a 1996 Johnson 225 Loop. Just as everyone has mentioned, it is too much power and I am getting on average of 2.0 mpg.
