Introduction
Product description
Welcome to the installation guide for the Raymarine rotary drive. This product is intended to
operate the boat's steering mechanism as part of a Raymarine autopilot system. It is designed
for steering systems that can be driven from the helm position through a chain and sprocket
(for example: cable and rod steering systems).
The outstanding design of the Raymarine rotary drive unit provides smooth, powerful
autopilot-controlled steering with quiet operation.
The main parts of the drive are:
• a rugged electric motor, that drives a precision epicyclic gearbox via a high tensile drive
belt
• an electromagnetic clutch that transmits high torque loads without slipping
