Abstract
The present invention is a trolling boat motor assembly that provides a motor displaced above the water line which is connected to a propeller shaft below the water line by one of a belt drive assembly, worm gear assembly, or flexible cable drive assembly. The motor is housed above the water line to limit the amount of noise transmitted through the water. There are noise insulating bushings placed beneath the motor to further limit the transmission of noise into the water and thus disturbing the marine life therein. There is a noise inversion device that transmits a signal 180 degrees out of phase from noise detected in the water, thereby reducing the amount of audible noise.
