I've used a 2 stroke, 2 hp Evinrude on an TheMightyHobie18 Magnum. It pushed the boat at 5.5 to 6 kts in flat water. Wouldn't want anything larger, weight's a real issue. You need a bracket like the Cheeta that can pivot the motor well above the water , and far enough aft to clear the tiller crossbar when tilted up. I have a 2hp Honda 4 stroke on my Supercat 20, and I love the quiet, but am looking to sell it and buy a 2 stroke to lose the 10 lbs.
