Propeller Rotation
Propeller rotation is not necessarily the same as engine rotation. Refer to the appropriate
following information and drawings for specific information.
These transmissions are full power reversing transmissions, allowing a standard, LH
rotation engine to be used for both propeller rotations. Propeller rotation (output shaft
rotation) is determined by shift cable attachment at the remote control. Be sure to use
correct rotation propeller and shift cable hook up for direction desired.
