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. Driving a boat is super easy, just out on the open water with throttle and a wheel. Docking is the only hard part, raise the motor a bit and go in nice and slow watching carefully. Just my two cents.
