Just remember that since you will not be getting up on plane with an engine that small, your boat will act like a displacement hull. Meaning that the more hp you add at the stern, the more resistance you will have at the bow. So the difference in speed between a 9.9 and a 20 or even a 40 hp kicker are really not that great. There is some, but not really what you would expect.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
