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.
CAUTION
Linear drive
This drive moves the rudder directly from the tiller arm or rudder quadrant.
Before installing the drive, check that the boat’s steering system can be backdriven from the rudder..
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 autopilot 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
