Connecting Optional NMEA 2000 Devices to the Autopilot System
You can use advanced features of the autopilot system by connecting optional NMEA 2000 compatible devices,
such as a GPS device, to the NMEA 2000 network.
1 Add an additional T-connector (not included) to the NMEA 2000 network backbone.
2 Connect the optional NMEA 2000 device to the T-connector by following the instructions provided with the
device.
Bleeding the Hydraulics
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.
6 Turn on the autopilot system and disable the Shadow Drive sensor.
You can refer to the owner's manual for your helm control or chartplotter for more information on disabling
the Shadow Drive.
7 Hold <1° (port) on the helm control or chartplotter for at least 10 seconds.
TIP: You can stop holding <1° when you no longer see air moving through the bypass hose.
8 Close both bypass valves at the cylinder fittings.
9 If necessary, add fluid to the helm reservoir.
10 Repeat steps 3 through 9 for the starboard side.
11 Hold <1° (port) on the helm control or chartplotter until steering stops and Hydraulic Pump Stall appears.
12 Hold 1°> (starboard) on the helm control or chartplotter until steering stops and Hydraulic Pump Stall
appears.
13 Select an option:
• If Hydraulic Pump Stall dows not appear within 2 to 3 seconds after the cylinder stops, repeat steps 1-13
to bleed the system again.
• If Hydraulic Pump Stall appears within 2 to 3 seconds after the cylinder stops, the system bleed
completed successfully.
After hydraulic bleeding is complete, you can re-enable the Shadow Drive sensor.
Configuration
The autopilot must be configured and tuned to your boat dynamics. You can use the Dockside Wizard and the
Sea Trial Wizard on the helm control or a compatible Garmin chartplotter to configure the autopilot.
See the included configuration guide for more information on configuring the autopilot.
