Abstract: A watercraft can have an electric motor mounted on a screw bar extending in a right/left direction. The electric motor can move along the screw bar in the right/left direction to steer an outboard motor, or another part of a different marine propulsion system. One or more springs can be provided at the ends of the screw bar. When the outboard motor whose steered angle exists in a predetermined angle range including the maximum steered angle is steered back to a neutral position, either one of the springs presses the electric motor toward the center of the screw bar to assist the steering torque of the electric motor.
