Introduction
Product description
Welcome to the installation guide for the Raymarine linear drive. This product is intended to
operatethe 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

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 back-
driven from the rudder..

1. EMC installation guidelines
All Raymarine equipment and accessories are designed to the best industry standards for use
in the recreational marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic Compatibility
(EMC) standards, but correct installation is required to ensure that performance is not
compromised. Although every effort has been taken to ensure that they will perform under all
conditions, it is important to understand what factors could affect the operation of the
product.
The guidelines given here describe the conditions for optimum EMC performance, but it is
recognized that it may not be possible to meet all of these conditions in all situations. To
ensure the best possible conditions for EMC performance within the constraints imposed by
any location, always ensure the maximum separation possible between different items of
electrical equipment.
For optimum EMC performance, it is recommended that wherever possible:
• Raymarine equipment and cables connected to it are:
WARNING

Make sure you have switched OFF the power supply before you start
installing this product.

• At least 3 ft (1 m) from any equipment transmitting or cables carrying radio signals
e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be
increased to 7 ft (2 m).
• More than 7 ft (2 m) from the path of a radar beam. A radar beam can normally be
assumed to spread 20 degrees above and below the radiating element.
• The equipment is supplied from a separate battery from that used for engine start. Volt-
age drops below 10 V, and starter motor transients, can cause the equipment to reset. This
will not damage the equipment, but may cause the loss of some information and may
change the operating mode.
• Raymarine specified cables are used. Cutting and rejoining these cables can compromise
EMC performance and must be avoided unless doing so is detailed in the installation
manual.
• If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the fer-
rite needs to be removed during installation it must be reassembled in the same position.
Suppression ferrites
The following illustration shows typical cable suppression ferrites used with Raymarine
equipment. Always use the ferrites supplied by Raymarine. This product has ferrites mounted
internally.
Figure 3: Typical suppression ferrites
Connections to other equipment
If your Raymarine equipment is to be connected to other equipment using a cable not
supplied by Raymarine, a suppression ferrite MUST always be attached to the cable near to
the Raymarine unit.

2. Mounting the drive
Mounting the drive unit involves four main steps:
• ensuring correct drive alignment
• securing the drive to the boat
• connecting the drive to the steering system
• completing a steering check
Drive alignment
When mounting the linear drive unit, check that it is aligned correctly:
• The main drive assembly must be at right angles to the mounting surface (see
Figure 4 ).
• The drive unit must be at right angles to the tiller arm when the rudder is amidships (see
Figure 4 ).
Figure 4: Drive unit alignment
• The push rod must be accurately aligned with the tiller arm plane of rotation. The ball end
fitting only allows up to 5 degrees misalignment between the push rod and tiller arm
plane of rotation (see
Figure 5 ).
CAUTION
Alignment
Accurate angular alignment is extremely important. You must not exceed this
+/- 5 degree limit under any circumstances.

Securing the drive
Mounting location
Before you secure the drive to your boat, you must first check the suitability of the mounting
location.
•Structural strength:
• This drive produces a considerable amount of force, so you must mount it on a solid
structure (i.e. a substantial frame member) inthe boat. In some cases youmay need to
build a special frame to mount the drive unit.
• To prevent excess noise and vibration, do not attach this drive to any structures that
support cabins.
•Drive orientation:
• You can attach the drive unit mounting foot to any suitable horizontal or vertical sur-
face. If required, you can also mount the drive unit upside down.
•General position:
• Refer to the EMC installation guidelines (
page 9 )
• Make sure the drive will be accessible for future servicing.
•Environment:
• This drive is not waterproof, soyoushould mount it in a drylocation, clear ofany bilge
water.
CAUTION
Mounting location
Consult the boat manufacturer if you have any doubt about the strength or
suitability of the mounting location.
