Testing and Adjusting the Configuration
NOTICE
Test the autopilot at a slow speed. After the autopilot has been
tested and adjusted at a slow speed, test it at a higher speed to
simulate normal operating conditions.
1
Drive the boat in one direction with the autopilot engaged
(heading hold).
The boat may oscillate slightly, but it should not oscillate
significantly.
2
Turn the boat in one direction using the autopilot and observe
the behavior.
The boat should turn smoothly, not too quickly or too slowly.
When you turn the boat using the autopilot, the boat should
approach and settle on the desired heading with minimal
overshoot and oscillation.
3
Select an option:
• If the boat turns too quickly or too sluggishly, adjust the
autopilot acceleration limiter (Adjusting the Acceleration
Limiter Settings).
• If the heading hold oscillates significantly or the boat does
not correct when turning, adjust the autopilot gain
(Adjusting the Autopilot Gain Settings).
• If the boat turns smoothly, the heading hold oscillates only
slightly or not at all, and the boat adjusts the heading
correctly, the configuration is correct, and no further
adjustments are necessary.
Adjusting the Acceleration Limiter Settings
1
Enable Dealer Mode (Enabling Dealer Configuration).
2
Select Menu > Setup > Dealer Autopilot Setup > Autopilot
Tuning > Acceleration Limiter.
3
Select an option:
• Increase the setting if the autopilot turns too quickly.
• Decrease the setting if the autopilot turns too slowly.
When you manually adjust the acceleration limiter, make
relatively small adjustments. Test the change before making
additional adjustments.
4
Test the autopilot configuration.
5
Repeat steps 3–4 until the autopilot performance is
satisfactory.
Adjusting the Autopilot Gain Settings
1
Enable Dealer Mode (Enabling Dealer Configuration).
2
Select Menu > Setup > Dealer Autopilot Setup > Autopilot
Tuning > Rudder Gains.
3
Select an option based on the type of boat:
• If you have a sailboat, a displacement-hull powerboat, or a
powerboat with the speed source set to None, select Gain
and adjust how tightly the rudder holds the heading and
makes turns.
If you set this value too high, the autopilot may be
overactive and attempt to constantly adjust the heading at
the slightest deviation. An overactive autopilot can drain
the battery at a faster-than-normal rate.
• If you have a sailboat, a displacement-hull powerboat, or a
powerboat with the speed source set to None, select
Counter Gain and adjust how tightly the rudder corrects
the turn overshoot.
If you set this value too low, the autopilot can overshoot
the turn again when it attempts to counter the original turn.
• If you have a planing-hull powerboat with the speed
source set to Tach. - NMEA 2000 or Proprietary or GPS,
select Low Speed or High Speed and adjust how tightly
the rudder holds the heading and makes turns at low
speed or high speed.
If you set this value too high, the autopilot may be
overactive and attempt to constantly adjust the heading at
the slightest deviation. An overactive autopilot can drain
the battery at a faster-than-normal rate.
• If you have a planing-hull powerboat with the speed
source set to Tach. - NMEA 2000 or Proprietary or GPS,
select Low Speed Counter or High Speed Counter to
adjust how tightly the rudder corrects the turn overshoot.
If you set this value too low, the autopilot can overshoot
the turn again when it attempts to counter the original turn.
4
Test the autopilot configuration, and repeat steps 2 and 3
until the autopilot performance is satisfactory.
Advanced Configuration
Advanced configuration options are not available on the helm
control under normal conditions. To access the advanced
configuration settings of the autopilot, you must first enable
Dealer Mode (Enabling Dealer Configuration).
Enabling Dealer Configuration
1
From the heading screen, select Menu > Setup > System >

2
Hold the center key for 5 seconds.
Dealer Mode appears.
3
Select Back > Back.
If the option for Dealer Autopilot Setup is available on the Setup
screen, the procedure was successful.
Advanced Configuration Settings
You can run the autotune process, calibrate the compass, and
define north on the autopilot without running the wizards. You
can also define each setting individually, without running the
configuration processes.
Running the Automated Configuration Processes Manually
1
Enable Dealer Mode (Enabling Dealer Configuration).
2
From the heading screen, select Menu > Setup > Dealer
Autopilot Setup.
3
Select an automated process:
