Yes, lower sound level is a big plus. I'd suggest checking the prop
pitch that comes with the motor. Most are pitched too high for slow
speed sailboat usage. A lower pitch will get you operating further
up on the torque curve and will make your engine happier over the long
run.

While the thru-the-propeller exhaust helps keep noise down, it really
ruins
reverse thrust!


If somebody needs reverse thrust they're not much of a sailboat operator.
You can't stop a 4-ton sailboat with a little reverse thrust from a six HP
motor in anything less than about fifty feet if the boat is traveling about
three knots. A good sailor allows his forward motion, leeway etc. to come to
a stop at the same point it arrives at a solid object. He does this without
the assistance of a motor.

I just laugh so hard I almost wet myself when I see any boat approach a dock
at about five knots, then throw it in reverse and max throttle the thing to
a stop. Ludicrous! An accident waiting to happen and a very lubberly thing
to do.

The prop for the Sail Pro is 8.375" Dia. X 6.0" Pitch High-Thrust 3-Blade

The prop for the Standard model is 7.7" Dia. X 8.0" Pitch 3-Blade Aluminum


The Sail Pro seems propped just about right to me.
