I have a 1978 CP-16. Right now, I have a 45 pound electric trolling motor. Someone is offering me a 9.9 HP 2 stroke for free (yes, good working order). I can have if it I want, but I don't know if that will be too much for the boat. My typical use would be getting in and out of my lake marina, but I might also want to quickly head to parts of the lake 9 miles away. In those circumstances, the speed would be perfect. My wife would also feel more comfortable with a gas motor since I have two small kids and she seems to think electric motors run on voodoo.
