A motor assembly for rotating an underwater mounted device around a troll motor shaft. The motor assembly may have a hub fix part, a top ring, a gear ring having an inner surface covered with a plurality of gear teeth, a bottom ring, a motor mounting plate, a stepper motor attached to the motor mounting plate, a stepper motor shaft rotated by the stepper motor and a spur gear pinion attached to the stepper motor shaft. The hub fix part, top ring, gear ring, bottom ring and motor mounting plate are configured, when positioned on top of each other, to form an inner chamber in the motor assembly. The stepper motor may rotate the spur gear pinion inside the chamber. The spur gear pinion may engage with the plurality of gear teeth of the gear ring to thereby rotate the motor assembly about an axis of the troll motor shaft.
