I've got a 16 foot AIRE cataraft that I would like to run with an outboard. considering 9.9 to 30 horses. Can an outboard take a few hits at 15 mph and live through it? I would like to be able to use the motor in whitewater, shallow water, and have a safe prop guard for rescueing swimmers. Ive looked at army surplus "jet pumps", that are real similar to conventional outboard. they seem reasonably priced and come in a 30 hp johnson. The normal outboard jet doesnt sound compatible with a cat hull. any suggestions? <br />Rob
