Re: Fuel Mileage
I had a 23' pennyan with a single 305 and got about 3 mpg at cruise, very heavy boat for a 23 footer. Mileage was about that if I could stay below 34 or 3500 rpms after that the four barrel kicked in and you know what happens then. Your likely get between 1.7 and 2 depending on load and sea conditions.
