I'm not sure how I misquoted anything.
I was only wondering if having a reduction gear would make you use more power to go a designated distance as opposed to using direct drive?

Wow! Somehow my post on this thread is misquoted. Truth be told none of my post was quoted.
Anyhow, as long as the motor is turning it is not locked rotor. In the past some have said direct drive did not work for them.
A motor rpm is a mechanical thing( much better that it stays together right?).Running at slower rpm the fan will not move as much air. Better to remove the motors fan and use a thermostat controlled fan to keep the motor heat within design limits.
Keep in mind the hp ratings of an electric motor is with fan in place, you will be increasing hp a little bit and not use as many watts if the fan has been removed. You will still use power with the external fan, but because your fan is better controlled you should not use as much.

Another thing that would seem to be problematic with using a reduction gear would be that higher RPM would mean greater power consumption for distance covered. Is this true?

Can anyone confirm this is accurate and does anyone here use their motor without the gear reduction and simply avoid pushing the motor higher than the 2500 rpm the prop works best at?
