Connecting the Hydraulic Hoses to the Pump
For assistance, see the layout diagrams (
).
1 Disconnect the necessary hoses from the hydraulic system.
2 Add a T-connector to the starboard and port hoses of the hydraulic 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 return hose connected to the helm, add enough hydraulic hose to connect the
return fitting on the helm to the pump.
• If the boat has a return hose connected to the helm, add a T-connector to the return hose.
NOTE: If the boat has a power-assist module, you must add the T-connector to the return hose between
the power-assist module and the helm.
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 Install a shut-off valve (not included) on each hydraulic hose from the T-connector to the pump.
6 If you added hydraulic hose to the return fitting on the helm, install a shut-off valve (not included) on the
hydraulic hose from the helm to the pump.
7 Connect the starboard hose from the T-connector, through a shut-off valve, to a pump fitting labeled with a
C1 or C2.
8 Connect the port hose from the T-connector, through a shut-off valve, to the other pump fitting labeled with
a C1 or C2 that you did not use in the previous step.
9 Complete an action:
• If you added hydraulic hose to the return fitting on the helm, connect the return hose from the helm,
through a shut-off valve, to the pump fitting labeled with a T.
• If you added a T-connector to an existing return hose, connect the return hose from the T-connector,
through a shut-off valve, to the pump fitting labeled with a T.
10 Install the Shadow Drive valve in the port or starboard hydraulic hose between the helm and the T-connector
that connects to the pump.
See the installation instructions provided in the autopilot corepack when installing the Shadow Drive valve.
11 Insert, tighten, and seal the included plugs in the unused pump fittings, if they are not already in place.
Connection Considerations
• You should mount the SmartPump and connect it to the hydraulic system before connecting the SmartPump
to power and to the CCU.
• The ports on the SmartPump labeled POWER and CCU are the only ports used in a typical installation.
• The port on the SmartPump labeled FEEDBACK is used only when installing an optional rudder feedback
sensor.
Completing the Installation
1 Follow the instructions included in the autopilot corepack to install the rest of the autopilot components.
2 Follow the instructions included in the autopilot corepack to bleed the air from the hydraulic system.
3 Apply a marine corrosion inhibitor spray to the SmartPump to ensure corrosion resistance.
Garmin recommends that you re-apply the marine corrosion inhibitor once each year to extend the life of the
SmartPump.
