I had a cheetah bracket on my H21SE and when I did Catalina trips I bought a Honda 2hp. The thing worked fantastic. On more than one occasion, due to no wind and needing to get home, I motored all the way to Marina Del Rey from Avalon (50 plus miles). I carried two 1gallon gas cans. If I remember, I think I could motor about 25 miles on less than one of those. Optimum speed was about 6-7 knots at half throttle. One thing that made that Honda the best was that it was air cooled. No needing to flush it with fresh water really, I never did.
