Hit 5,000 miles today. Last weekend I pulled the boat (4,500 lbs) about 250 miles and got around 15.5 mpg. Probably could have done better but I was doing 70 mph. Wish the boat went that fast, or got that kind of mpg... 54 mph is the top end for the boat and I don't even want to know how much gas it uses at 5700 rpm.
