Installation Instructions

Important Safety Information

 WARNING

See the 

Important Safety and Product Information

 guide in the 

product box for product warnings and other important 

information.
You are responsible for the safe and prudent operation of your 

vessel. The autopilot is a tool that enhances your capability to 

operate your boat. It does not relieve you of the responsibility of 

safely operating your boat. Avoid navigational hazards and 

never leave the helm unattended.
Always be prepared to promptly regain manual control of your 

boat.
Learn to operate the autopilot on calm and hazard-free open 

water.
Use caution when operating the autopilot near hazards in the 

water, such as docks, pilings, and other boats.

 CAUTION

When in use, beware of hot motor and solenoid components 

and the risk of entrapment from moving parts.
Failure to install and maintain this equipment in accordance with 

these instructions could result in damage or injury.

NOTICE

To avoid damage to your boat, the autopilot system should be 

installed by a qualified marine installer. Specific knowledge of 

hydraulic steering componentry and marine electrical systems is 

required for proper installation.

Installation Preparation

The autopilot system consists of multiple components. You 

should familiarize yourself with all of the component mounting 

and connection considerations before beginning installation. You 

must know how the components operate together in order to 

correctly plan the installation on your boat.
You can consult the layout diagrams (

Power and Data Layout

page 2

) to help understand the mounting and connection 

considerations.
You should lay out all of the components on the boat as you 

plan the installation to make sure your cables will reach each 

component. If needed, extension cables (sold separately) for 

various components are available from your Garmin dealer or 

from 

www.garmin.com

.

You should record the serial number of each component for 

registration and warranty purposes.

Tools Needed

• Safety glasses
• Drill and drill bits
• Wrenches
• 90 mm (3.5 in.) hole saw or a rotary cutting tool (for installing 

an optional helm control)

• Wire cutters/strippers
• Phillips and flat screwdrivers
• Cable ties
• Single Pole Single Throw (SPST) switch (to use as an 

autopilot bypass when not installing the Shadow Drive

valve)

• Waterproof wire connectors (wire nuts) or heat-shrink tubing 

and a heat gun

• Marine sealant
• Marine corrosion inhibitor spray
• Portable or handheld compass (to test for magnetic 

interference)

• Hydraulic hose with machine-crimped or field-replaceable 

fittings that have a minimum rating of 1000 psi

• Hydraulic T-fittings
• Hydraulic fluid
• Thread sealant
• Hydraulic bleeding equipment

NOTE: 

Mounting screws are provided for the main components 

of the autopilot system. If the provided screws are not 

appropriate for the mounting surface, you must provide the 

correct types of screws.

Mounting and Connection Considerations

The autopilot components connect to each other and to power 

using the included cables. Ensure that the correct cables reach 

each component and that each component is in an acceptable 

location before mounting or wiring any components.

CCU Mounting and Connection Considerations

• The CCU is the primary sensor of the Reactor 40 Compact 

Hydraulic autopilot system. For best performance, observe 

these considerations when selecting a mounting location.
◦ A handheld compass should be used to test for magnetic 

interference in the area where the CCU is to be 

mounted(

Testing a Location for Magnetic Interference

page 2

).

◦ The CCU should be mounted on a rigid surface for best 

performance.

• Mounting screws are provided with the CCU. If you use 

mounting hardware other than the provided screws, the 

hardware must be quality stainless or brass material to avoid 

magnetic interference with the CCU.
Test any mounting hardware with a handheld compass to 

make sure no magnetic fields are present in the hardware.

• The CCU cable connects the CCU to the ECU and is 5 m 

(16 ft.) long.
◦ If the CCU cannot be mounted within 5 m (16 ft.) of the 

ECU, extension cables are available from your local 

Garmin dealer or at 

www.garmin.com

.

◦ This cable must not be cut.

Finding the Best Mounting Location

1

Create a list of all suitable mounting locations for the CCU.
Suitable mounting locations should not be within 60 cm (2 ft.) 

of the following:
• Iron
• Magnets
• High-current wires
• Intermittently-running pumps, such as head pumps and 

live well pumps

A large magnet, such as a subwoofer-speaker magnet, 

should be no closer than 1.5 m (5 ft.) to any of the mounting 

locations.
