Before you mount the pump, if your boat has an unbalanced cylinder 

steering system, you must re-configure the pump to work properly with 

the unbalanced cylinder (

).

1.  After you select a mounting location, determine the mounting 

hardware needed for the surface.
Mounting hardware is included with the pump, but it may not be 

suitable for the mounting surface.

2.  If necessary, purchase the mounting hardware.
3.  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.

4.  Using a drill bit appropriate for the mounting surface and selected 

mounting hardware, drill the four holes through the mounting 

surface.

5.  Secure the pump to the mounting surface using the selected 

mounting hardware.

Do not attempt to use the autopilot to steer the boat until you bleed all 

When adding hydraulic line to the system, use only hose with machine-

crimped or field-replacable fittings that have a minimum rating of  

1000 lbf/in

.

Do not use plumber’s tape on any hydraulic fitting. Use an appropriate 

thread sealant rated for marine use on all pipe threads in the hydraulic 

system.
Before you connect the pump to the hydraulic lines, refer to one of these 

diagrams to find the correct place to add the pump and fittings to the 

hydraulic system. 
•  Single helm without power assist (

•  Dual helm without power assist (

•  Single helm with power assist (

)

•  Five-connector install method (

page 8

)

The diagrams on 

 show the recommended pump installation 

method, with t-connectors in the hydraulic steering lines of the boat, 

using only three fittings on the manifold. However, it is possible to 

install the pump using the five-connector method shown on 

.

1.  Disconnect the necessary lines from the hydraulic system.
2.  Add a t-connector to the starboard and port lines of the system.
3.  Add hydraulic hose to the unused fitting on each t-connector, 

sufficient to connect the t-connector to the pump fittings.

4.  Connect the starboard line t-connector to the H1 or H2 pump fitting. 
5.  Connect the port line t-connector to the H pump fitting that you did 

not use in step 4.

6.  Install the Shadow Drive to the port or starboard hydraulic line 

between the helm and the t-connector. 
See the installation instructions provided with your Garmin autopilot 

for Shadow Drive installation instructions.

7.  Connect the return line from the helm to the Tank fitting of the 

pump.

8.  Install a shut-off valve (

directly to the pump (optional).

9.  Insert, tighten, and seal the included plugs in the unused pump 

fittings.

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 t-connector and the steering cylinder.

3.  Add hydraulic hose to the unused fitting on each t-connector, 

sufficient to connect the t-connector to the pump fittings.

4.  Connect the starboard line t-connector to the H1 or H2 pump fitting. 
5.  Connect the port line t-connector to the H pump fitting that you did 

not use in step 4.

6.  Install the Shadow Drive to the port or starboard hydraulic line 

between the helm t-connector and the pump t-connector. 
See the installation instructions provided with your Garmin autopilot 

for Shadow Drive installation instructions.

7.  Connect the return line from the helm t-connector to the Tank fitting 

of the pump.

8.  Install a shut-off valve (

) on each hydraulic line that connects 

directly to the pump (optional).

9.  Insert, tighten, and seal the included plugs in the unused pump 

fittings.

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 power assist module and the steering cylinder.

3.  Add hydraulic hose to the unused fitting on each t-connector, 

sufficient to connect the t-connector to the pump fittings.

4.  Connect the starboard line t-connector to the H1 or H2 pump fitting. 
5.  Connect the port line t-connector to the H pump fitting that you did 

not use in step 4.

6.  Install the Shadow Drive to the port or starboard hydraulic line 

between the helm and the t-connector. 
See the installation instructions provided with your Garmin autopilot 

for Shadow Drive installation instructions.

7.  Add a t-connector to the return line between the power assist module 

and the helm.

8.  Connect the return line from the helm to the Tank fitting of the 

pump.

9.  Install a shut-off valve (

) on each hydraulic line that connects 

directly to the pump (optional).

10. Insert, tighten, and seal the included plugs in the unused pump 

fittings.

Garmin recommends the installation of shut-off valves on each 

line connected to the pump. The shut-off valves allow you to easily 

disconnect and remove the pump from the hydraulic system without 

affecting helm steering. Refer to the diagrams on 

 to view 

ideal shut-off valve placement.

Before you connect the pump to the ECU, you must mount the pump  

) and ECU. 

See the installation instructions provided with your Garmin autopilot for 

ECU installation instructions.

Connect the two cables from the pump to the ports on ECU marked 

DRIVE and FEEDBACK. 
The ports are keyed to the appropriate fittings on the cables.
