I have a 1971 9.9 hp Evinrude motor that is giving me a fit. Boat is a 1977 Cat. 22 swing keel. Looking for motor suggestions. like the power of the larger engine. May go into the ocean via a canal (Point Pleasant)and Barnaget inlet. Engine power is impt. and i am not racing at this point. Any brand/Hp suggestions ? Thanks!Hal
