Yeah I hear ya, I was thinking 7 and a bit GPH. If I get 8 well thats still pretty darn good for a boat of this size and style. I will let you know how she does. I have the fuel management system going in there so I will be able to figure out mileage easily with my different loads. Sadly the boat will be done in December which is right around the corner but I Wont have it out until march as I live in the North. so stay tuned. I'm definitely skeptical about those performance bulletins as well, so it will be interesting to see how far off they really are.
