******* Please note: Due to the high RPM of the Mars Brushless motor, we recommend using a gear reduction system rather than direct-drive. This will improve efficiency, provide proper torque and cooling, and prevent cavitation. Typical reduction is around 3:1, but will depend on the required prop RPM needed to reach hull speed. Proper reduction will enable the motor to spin your prop at the hull speed RPM of your prop when it is spinning at its max RPM. This number can be estimated using the 70 rpm/volt constant (48 volts * 70 rpm/volt ~ 3400 rpm max). *Appropriate prop required based on motor rpm and the boats hull speed.
