Steering system for small boat

摘要

A cylinder unit is provided in a rear side of a boat body to rotate an outboard motor main body as a steering apparatus, and a pump unit is provided to drive the pump unit via a hydraulic pipe by a steering wheel in a driver's seat. A steering torque inputted to the pump unit by the steering wheel is detected by a torque sensor. The pump unit is assisted in the steering operation direction based upon the detected torque by an electric motor, a worm gear, and a worm wheel.
