Turn on the autopilot system and disable the Shadow Drive.
You can refer to the autopilot system documentation for more
information on disabling the Shadow Drive.
7
Hold
(port) on the helm control for at least 10 seconds.
TIP:
You can stop holding
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
(port) on the helm control until steering stops and
Hydraulic Pump Stall
is shown on the helm control.
12
Hold
(starboard) on the helm control until steering stops
and
Hydraulic Pump Stall
is shown on the helm control.
13
Select an option:
• If
Hydraulic Pump Stall
is not shown within 2 to 3
seconds after the cylinder stops, repeat steps 1-13 to
bleed the system again.
• If
Hydraulic Pump Stall
is shown 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.
Corrosion Blocker
NOTICE
To ensure the long life of all parts, apply corrosion blocker to the
pump at least twice yearly.
A marine-rated corrosion blocker should be applied to the pump
after all hydraulic and electrical connections are made and the
hydraulic system has been bled.
Connecting the CCU
Route the orange and blue wires from the bare-wire portion
of the CCU cable to the location where you plan to install the
alarm (
Installing the Alarm
, page 8
).
If the cable is not long enough, extend the appropriate wires
with 0.08 mm
2
(28 AWG) wire.
Installing the Shadow Drive
Connecting the Shadow Drive to the Hydraulic System
Before you can install the Shadow Drive, you must select a
location at which to connect the Shadow Drive to the hydraulic
steering of your boat (
Shadow Drive Mounting Considerations
,
page 2
).
For further assistance, consult the hydraulic-layout diagrams
(
Hydraulic Layouts
, page 4
).
Use hydraulic connectors (not included) to install the Shadow
Drive in the appropriate hydraulic line.
Connecting the Shadow Drive to the CCU
1
Route the bare-wire end of the CCU cable to the Shadow
Drive.
If the cable is not long enough, extend the appropriate wires
with 28 AWG (0.08 mm²) wire.
2
Connect the cables, based on this table.
Shadow Drive Wire Color
CCU Cable Wire Color
Red (+)
Brown (+)
Black (-)
Black (-)
3
Solder and cover all bare-wire connections.
Installing an Autopilot Switch
If your autopilot package does not include a Shadow Drive
valve, you should install a manual Single Pole Single Throw
(SPST) switch (not included) to disable the autopilot if
necessary.
1
Route the bare-wire end of the CCU cable to the switch.
If the cable is not long enough, extend the appropriate wires
with 28 AWG (0.08 mm²) wire.
2
Connect the cables, based on this table.
Switch Wire Function
CCU Cable Wire Color
Positive (+)
Brown (+)
Negative (-)
Black (-)
3
Solder and cover all bare-wire connections.
The autopilot functions correctly when the switch contacts are
closed. Opening the switch disables the autopilot for manual
steering.
Installing the Alarm
Before you can mount the alarm, you must select a mounting
location (
Alarm Mounting and Connection Considerations
,
page 2
).
1
Route the alarm cable to the bare-wire end of the CCU cable.
If the cable is not long enough, extend the appropriate wires
with 28 AWG (0.08 mm
2
) wire.
2
Connect the cables, based on this table.
Alarm Wire Color
CCU Cable Wire Color
White (+)
Orange (+)
Black (-)
Blue (-)
3
Solder and cover all bare-wire connections.
4
Secure the alarm with cable ties or other mounting hardware
(not included).
NMEA 2000 and the Autopilot Components
A dedicated helm control is not included in all autopilot
packages. If you install the autopilot without a dedicated helm
control, the autopilot CCU must be connected to the same
NMEA 2000 network as a compatible Garmin chartplotter to
configure and control the autopilot system.
NOTICE
If you have an existing NMEA 2000 network on your boat, it
should already be connected to power. Do not connect the
NMEA 2000 power cable to an existing NMEA 2000 network,
because only one power source should be connected to a
NMEA 2000 network.
You can connect the CCU and the optional helm control through
an existing NMEA 2000 network. If you do not have an existing
NMEA 2000 network on your boat, all the parts needed to build
one are supplied in the autopilot package (
Building a Basic
NMEA 2000 Network for the Autopilot System
, page 8
).
To use the advanced features of the autopilot, optional NMEA
2000 devices, such as a GPS device, can be connected to the
NMEA 2000 network.
If you are unfamiliar with NMEA 2000, you should read the
“NMEA 2000 Network Fundamentals” chapter of the
Technical
Reference for NMEA 2000 Products
.
Building a Basic NMEA 2000 Network for the Autopilot
System
NOTICE
If you are installing a NMEA 2000 power cable, you must
connect it to the boat ignition switch or through another in-line
switch. NMEA 2000 devices will drain your battery if the NMEA
2000 power cable is connected to the battery directly.
A dedicated helm control is not included in all autopilot
packages. If you install the autopilot without a dedicated helm
control, the autopilot CCU must be connected to the same
NMEA 2000 network as a compatible Garmin chartplotter to
configure and control the autopilot system.
