Abstract: A self contained electro-mechanical arrangement for use in autopilot for yachts for securement to a steering wheel pedestal column is disclosed. The arrangement comprises a magnetic directional indicator, sensing apparatus associated with the magnetic directional indicator for determining movement thereof, and electrical drive controlled by the sensing apparatus. The electrical drive includes an electric motor, and a transmission, with the electric motor being bi-directional to allow rotation of the output shaft of the transmission in either direction. A mechanical drive is associated with the transmission for engaging the steering wheel shaft of such yacht wherein the motor and the directional indicator are separated to reduce any effect of the motor on the movement of the magnetic directional indicator.
