On the other hand... my 15 hp kicker on a 20' boat is more than enough
to reach hull speed leaving the top third of the throttle range useless
as it tries to climb the bow wave and the prop intermittently
ventilates. I would be happier with an 8hp and the weight and dollar
savings. The older 9.9 and 15 Honda's were the same block while the 8
was smaller/lighter. Other models may be different but in my experience
8-10 hp is plenty for that size boat.
