Mine runs 37-38 loaded heavy tornament plus load terova battires dog two people full of gas. I run a 16p turbo 4 blade Trolls 1.8-2.0 flat glass calm. Love the way this boat fishes the rear sponson really work in the big waves keep the back of boat up good and me dry backtrolling as far as speed goes we fished tornament on lake of wood end of June made the 24 mile run with all the guys running 300s they could not go any faster than us in the big waves. If it was calm they might have and extra 20-30 min to fish on 50 miles of running I like when we get gas at end of day only put 1/2 as much in as the guys running big motors. That means more $ for cranks and more time on the water.
