Sounds like someone either didnt have the motor trimmed properly, had an outrageous load or was pulling a elephant on a tube. There's no way you shouldve went through that much fuel!!Boats suck a TON of gas. I rented a 23 foot searay for 2 hrs and the gas alone cost me 200 dollars. It drank 40 gallons of gas going at 15-20 mph for 2 hours. Thats filling up your wk2 almost twice in two hours. Plus boat gas at the dock is like 5 bucks per gallon..
