Important information

Safety notices

WARNING: Product installation

This equipment must be installed and operated in accordance
with the instructions contained in this handbook. Failure to do so
could result in poor pr oduct performance, personal in jury and/
or damage to your boat.

Because correct performance of the boat’s steering is critical for
safet y, we STRONGLY RECOM MEND that an Autho rized
Raymarine Service Representative fits this product.

WARNING: Navigation aid

Although we have designed this p roduct to be accurate and
reliable, many factors can affect its performance. As a result, it
should only be used as an aid to navigation and should nev er
replace commo nsense and navigational jud gement. Always
maintain a permanent watch so you can res pond to situations as
they develop.

EMC conformance

All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment .
The design and manufacture of Raymarine equipment and
accessories conform to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to
ensure that performance is not compromised.

Handbook information

T o the best of our knowledge, the information i n this handbook was
correct when it went to press. However, Raymarine cannot accept
liability for any inaccuracies or omissions it may contain. In addition,
our policy of continuous product improvement may change
specifications without notice. As a result, Raymarine cannot accept

I/O Drive - Installation Guide 3

Introduction

Product description

W elcome to the installation gu ide for the Raymarine inboard/
outboard drive (also known as an I/O or st ern drive). This product is
intended to operate the boat’ s steering mechanism as part of a
Raymarine autopilot system.

It is designed to drive cable operated, power assisted steering
systems. It operates the power steering valve in the same way as the
steering cable. When you disengage the autopilo t, a clutch
disengages the I/O drive so you can steer the boat manually .

CAUTION:

Any attempt to install an I /O drive to a non-compatible engi ne
type may void the warranty on both the drive and the engine.

1. EMC installation guidelines

All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environmen t.

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 ef fort has been taken to ensure that
they will perform under all conditions, it is import ant to understand
what factors could affect the operation of the produ ct.

6 I/O Drive - Installation Guide

The guidelines given here describe the conditio ns for optimum EMC
performance, but it is recognized that it may not be possibl e to meet
all of these conditions in all situations. T o ensure the best possible
conditions for EMC performance within the constraint s imposed by
any location, always ensure the maximum separation possibl e
between different items of electrical equipment.

For optimum EMC performance, it is recommended that wherever
possible:

• Raymarine equipment and cables connected to it are:

• At least 3 ft (1 m) from any equipment transmi tting or cables

carrying radio signals e.g. VHF radios, cables and antennas.
In the case of SSB radios, the distance should be increased to
7ft (2m).

• 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. Voltage 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 i nformation 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 ins tallation manual.

• If a suppression ferrite is attached to a cable, this ferri te should not
be removed. If the ferrite needs to be removed during installation
it must be reassembled in the same position.

Suppression ferrites

Figur e 3 shows typical cable suppressi on ferrites used with
Raymarine equipment. Always use the ferrites supp lied by
Raymarine.

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.
