Introduction
Product description
Welcome to the installation guide for the Raymarine linear drive. This product is intended to
operate the boat’s steering mechanism as part of a Raymarine autopilot system. It is designed
for boats with existing mechanical steering systems.
The outstanding design of the Raymarine linear drive unit provides:
• powerful thrust, fast hardover times and quiet operation
• low backdrive force, to minimize the drive’s effect on the boat’s steering when the autopi-
lot is in standby
• a powerful electric motor controlled by an electromagnetic fail-safe clutch, using a high
tensile belt drive and epicyclic gearbox
• high performance for minimum current consumption

driven from the rudder..
