Route the bare-wire end of the ECU power cable to the boat 

battery.
If the wire is not long enough, it can be extended (

Power 

Cable Extensions

, page 7

).

3

Connect the black wire (-) to the negative (-) terminal of the 

battery, and connect the red wire (+) to the positive (+) 

terminal of the battery.

4

After you install all of the other autopilot components, 

connect the power cable to the ECU.

Power Cable Extensions

If necessary, the power cable can be extended using the 

appropriate wire gauge for the length of the extension.

Pump Installation

Mounting the Pump

Before you can mount the pump, you must select a location 

(

Pump Mounting Considerations

, page 2

) and determine the 

correct mounting hardware (

Tools Needed

, page 1

).

1

Hold the pump in the intended mounting location and mark 

the locations of the mounting holes on the mounting surface, 

using the pump as a template.

2

Using a drill bit appropriate for the mounting surface and 

selected mounting hardware, drill the four holes through the 

mounting surface.

3

Secure the pump to the mounting surface using the selected 

mounting hardware.

Connecting the Hydraulic Lines to the Pump

Refer to the layout diagrams for assistance (

Hydraulic Layouts

page 4

).

1

Disconnect the necessary lines from the hydraulic system.

2

Add a T-connector to the starboard and port lines of the 

system between the helm and the steering cylinder.

NOTE: 

If the boat has a power-assist module, you must add 

the T-connectors between the power-assist module and the 

steering cylinder.

3

Complete an action:
• If the boat does not have a power-assist module, add

enough hydraulic hose to connect the return fitting on the

helm to the center pump fitting.

• If the boat has a power-assist module, add a T-connector

to the return line of the system between the power-assist

module and the helm. A return line should already exist

between the helm and the power-assist module.

4

Add hydraulic hose to the unused fitting on each T-connector, 

with enough hose to connect the T-connector to the pump 

fittings.

5

Connect the port and starboard line T-connectors to the 

appropriate pump fittings, as shown in the layout diagram for 

your hydraulic configuration.

6

Install the Shadow Drive in the port or starboard hydraulic 

line between the helm and the T-connector (

Installing the 

Shadow Drive

, page 8

).

7

Install a shut-off valve (not included) on each hydraulic line 

that connects directly to the pump.

Bleeding the Hydraulics

NOTICE

This is a general procedure for bleeding a hydraulic steering 

system. Refer to the instructions provided by the manufacturer 

of the steering system for more-specific information about 

bleeding the system.

Before you bleed the hydraulic system, you should verify that all 

hose connections are complete and fully tightened.

1

Select an option:
• If the helm reservoir contains insufficient fluid, fill it as

needed.

• If the helm reservoir contains excess fluid, remove the

excess to avoid fluid overflow during the bleeding process.

2

Insert a bypass hose between the cylinder bleed ports.

TIP: 

If you use a clear plastic hose for this bypass, you can 

observe air bubbles during the bleeding processes.

3

Manually steer the helm fully to port.

4

Open both bypass valves at the cylinder fittings.

5

Manually turn the helm slowly to port over three minutes.

TIP: 

You can stop turning when you no longer see air moving 

through the bypass hose.
