I agree with everyone else, get a 2 horse, it will do just fine.
Probably, note I said probably go as fast as with a three.

In case you need one, I have some of the Neptune 17lb Mighty Mites that were
returned for warranty back in 91. Excellent little motors. Not to be confused
with the "weedeater" type: Tanaka, Cruise N Carry etc. throw away motors. Also
bought all their new parts. I use one on my canoe all the time (side bracket)
I run upstream a ways from put in point and float back down. Saves having to
shuttle vehicles & I can go alone. Contact me off group if you need one. Greg
