Hydraulic Linear Drive - Installation Guide
Introduction
Contents
Welcome to the installation guide for the Raymarine hydraulic linear
drive system. This product is intended to operate the boat's steering
mechanism as part of a Raymarine autopilot system.
The hydraulic linear drive system is designed for boats with existing
mechanical steering systems, not hydraulic steering systems. It
provides a totally isolated autopilot steering system consisting of:
• Hydraulic ram: a self-contained autopilot steering cylinder with a
load limiting system and a built in clutch (to allow friction-free
steering when the autopilot is not in use).
• Reversing hydraulic pump: powers the hydraulic ram.
• Hydraulic fluid reservoir: supplies hydraulic fluid to the system.
CAUTION:
The ram drives the rudder directly from the tiller arm or rudder
quadrant. Before installing this drive unit, check that the boat's
steering system can be backdriven from the rudder.
