Mike,
If you reduce the diameter to 37.50 mm and take a little cup out of the trailing edge (3.21")
you can put the motor deeper in the water, and the propeller will be even more efficient.
Most are running the stock propeller too high because of the cup and diameter are too
much in the stock configuration. If you tried one modified this way you would see the
difference in RPM. Don't get me wrong it is a great propeller, but once we made the
modifications we saw our lap times drop 1/2 second per lap.
Enjoy Testing Everyone,
Mark Sholund
