REACTOR™ 40 KICKER
CONFIGURATION GUIDE
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the product box for product warnings and other
important information.
To avoid possible personal injury and damage to your boat, the autopilot system should be installed by a
qualified marine installer. Specific knowledge of marine steering and electrical systems is required for proper
installation.
You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances your
capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. Avoid
navigational hazards and never leave the helm unattended.
Always be prepared to promptly regain manual control of your boat.
If your motor features a kill switch, you should know how to operate it in case of an emergency. If your motor
does not feature a kill switch, you should install one before installing the autopilot system.
Learn to operate the autopilot on calm and hazard-free open water.
Use caution when operating the autopilot near hazards in the water, such as docks, pilings, and other boats.
CAUTION
Failure to install and maintain this equipment in accordance with these instructions could result in damage or
injury.
When in use, beware of hot surfaces on the heat-sink, motor, and solenoid components.
When in use, beware the risk of entrapment or pinching from moving parts.
Configuring the Autopilot
The autopilot system must be configured and tuned to your boat dynamics. You should use the Dockside
Wizard and the Sea Trial Wizard to configure the autopilot. These wizards walk you through the necessary
configuration steps.
If your autopilot package did not contain a helm control, you must configure the autopilot system using a
compatible chartplotter on the same NMEA 2000® network as the autopilot CCU. These instructions address
configuration using either a helm control or a chartplotter.
Dockside Wizard
CAUTION
When performing you perform the Dockside Wizard while your boat is either in or out of the water, provide
rudder-movement clearance to avoid damage to the rudder or other objects, and use caution to avoid personal
injury that may be caused by moving parts.
You can complete the Dockside Wizard while the boat is in or out of the water.
If the boat is in the water, it must be stationary while you complete the wizard.

Sea Trial Wizard
The Sea Trial Wizard configures the fundamental sensors on the autopilot, and it is extremely important to
complete the wizard in conditions appropriate for your boat.
Important Sea Trial Wizard Considerations
The Sea Trial Wizard must be completed in calm water. Because the nature of calm water is relative to the size
and shape of the boat, before you begin the Sea Trial Wizard, the boat must be in an appropriate location.
• The boat must not rock while sitting still or moving very slowly.
• The boat must not be significantly affected by the wind.
While completing the Sea Trial Wizard, observe these considerations.
• Weight on the boat must remain balanced. While completing any of the steps in the Sea Trial Wizard, do not
move around on the boat.
Performing the Sea Trial Wizard
1 Drive your boat to an open area of calm water.
2 On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot
Installation Setup > Wizards > Sea Trial Wizard > Begin
3 If necessary, enter the maximum speed of the boat when powered by the kicker motor only.
4 If necessary, enter 6000 as the maximum RPM value for your kicker motor.
7 Set north (Setting North, page 4), or set the fine heading adjustment (Setting the Fine Heading Adjustment,
page 5).
Calibrating the Compass
1 Select an option:
• If you are performing this procedure as part of the Sea Trial Wizard, select Begin.
• If you are performing this procedure outside of the Sea Trial Wizard, on a helm control or the autopilot
screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation Setup > Compass Setup >
Compass Cal. > Begin.
2 Follow the directions until calibration is complete, taking care to keep the boat as steady and flat as
possible.
The boat should not list during calibration. Make sure one side of the vessel is not loaded more heavily than
the other.
3 Select an option:
• If the calibration is not successful, repeat the previous step.
• If the calibration completes successfully, select Next.
When the calibration is complete, a magnetic environment quality value is shown. A value of 100 indicates the
CCU was installed in a perfect magnetic environment and calibrated correctly. If this value is low, you might
need to relocate the CCU and calibrate the compass again.
3
Performing the Autotune Procedure
Before you can begin this procedure, you must have a large stretch of open water available.
1 Engage the kicker motor in forward gear at moderate speed.
2 Steer the boat by hand and point in a direction with at least 100 to 200 m (100 to 200 yd.) of open water.
3 Select an option:
• If you are performing this procedure as part of the Sea Trial Wizard, select Begin.
• If you are performing this procedure outside of the Sea Trial Wizard, on a helm control or the autopilot
screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation Setup > Autopilot Tuning >
Autotune > Begin.
The boat performs various zigzag motions while the Autotune is in progress.
4 After the procedure is finished, follow the on-screen instructions.
5 If the Autotune procedure is not successful, select an option:
• If the Autotune procedure is not successful and you have not reached maximum cruising speed, increase
the speed, select Run Standard Autotune and repeat steps 1 through 3 until the Autotune procedure
completes successfully.
• If the Autotune procedure is not successful and you have reached maximum cruising speed, reduce your
speed to the initial Autotune speed, and select Run Alternate Autotune to begin an alternate procedure.
• If the Autotune fails immediately and you are traveling in a circle instead of performing zigzag motions,
select Switch Direction > Run Standard Autotune and repeat steps 1 through 3 until the Autotune
procedure completes successfully.
When the Autotune procedure is complete, gain values are displayed. You can use these values to determine the
quality of the Autotune procedure.
Autotune Gain Values
After the Autotune procedure is complete, you can review the gain values provided on the helm control. You can
record these numbers for reference if you want to run the autotune procedure at a later time or if you want to
manually adjust the gain settings (not recommended) (Adjusting the Autopilot Gain Settings, page 6).
Gain: Sets how tightly the autopilot holds the heading and how aggressively it makes turns.
Counter Gain: Sets how aggressively the autopilot adjusts any over-steering after making a turn.
Setting North
Before you can begin this procedure, you must have a large stretch of open water available.
This procedure appears if the autopilot is connected to an optional GPS device, and the device has acquired
a GPS position. During this procedure, the autopilot aligns the compass heading with the Course over Ground
(COG) information from the GPS device.
If you do not have a GPS device connected, you are prompted to set the fine heading adjustment instead
1 Drive your boat at in a straight line at cruising speed, downwind, and in the same direction as the current.
2 Select an option:
• If you are performing this procedure as part of the Sea Trial Wizard, select Begin.
• If you are performing this procedure outside of the Sea Trial Wizard, on a helm control or the autopilot
screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation Setup > Compass Setup >
Set North > Begin.
3 Continue to drive the boat in a straight line at cruising speed, downwind, in the same direction as the current,
and follow the on-screen instructions.
4 Select an option:
• If the calibration is not successful, repeat the previous step.
• If the calibration completes successfully, select Next.
4
Setting the Fine Heading Adjustment
This procedure appears only if you do not have an optional GPS device connected to the autopilot. If the
autopilot is connected to a GPS device that has acquired a GPS position, you are prompted to set north instead
1 Select an option:
• If you are performing this procedure as part of the Sea Trial Wizard, proceed to step 2.
• If you are performing this procedure outside of the Sea Trial Wizard, on a helm control or the autopilot
screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation Setup > Compass Setup >
Fine Heading Adjustment.
2 Adjust the fine heading setting until it shows the correct heading as determined by a trusted heading
indicator, such as the ship compass or a handheld compass.
3 Select Back.
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
• If the heading hold oscillates significantly or the boat does not correct when turning, adjust the autopilot
• If the boat turns smoothly, the heading hold oscillates only slightly or not at all, the boat adjusts the
heading correctly, the configuration is correct. No further adjustments are necessary.
Adjusting the Acceleration Limiter Settings
1 On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot
Installation Setup > Autopilot Tuning > Accel. Limiter.
2 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.
3 Test the autopilot configuration.
4 Repeat steps 2 and 3 until the autopilot performance is satisfactory.
5
Adjusting the Autopilot Gain Settings
The autopilot gain settings are set during the Autotune procedure. Adjusting these values is not recommended,
and you should record the values set by the Autotune procedure before making any changes.
1 On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot
Installation Setup > Autopilot Tuning > Rudder Gains.
2 Select an option based on the type of boat:
• If you have a planing-hull powerboat with the speed source set to Tach. - N2K or Proprietary, Tachometer,
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. - N2K or Proprietary, Tachometer,
or GPS, select Low Spd. Cntr. 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.
3 Test the autopilot configuration, and repeat step 2 until the autopilot performance is satisfactory.
Advanced Configuration Settings
You can calibrate the compass, run the autotune procedure, and set north on the autopilot without running the
wizards. You can also manually define each setting individually, in order to make slight adjustments, without
running the full configuration or calibration processes.
Manually Running the Automated Configuration Processes
1 On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot
Installation Setup.
2 Select an automated process:
• To start the automatic autopilot tuning procedures, select Autopilot Tuning > Autotune (Performing the
• To start the procedures to define north, select Compass Setup > Set North (Setting North, page 4).
3 Follow the on-screen instructions.
Manually Defining Individual Configuration Settings
Configuring certain configuration settings may require you to modify other settings. Review the detailed
configuration settings section prior to modifying any settings (Detailed Configuration Settings, page 7).
1 On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot
Installation Setup.
2 Select a setting category.
3 Select a setting to configure.
Descriptions of each setting are available in this manual (Detailed Configuration Settings, page 7).
4 Configure the value of the setting.
6
Multiple Sources of Sensor Information
There may be multiple sources of sensor information available to the autopilot system. If so, you can select a
preferred data source.
For example, because GPS speed from an external antenna is more reliable and accurate than that from an
integrated GPS receiver inside a chartplotter, you should select the external GPS antenna as the preferred
source of GPS data. Also, because it can be difficult to find an ideal mounting location for the autopilot CCU, you
can optionally select an external NMEA 2000 GPS compass or other heading sensor as the preferred source of
heading data.
Selecting a Preferred Source of Sensor Information
1 On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Preferred Sources.
NOTE: Some items in the Preferred Sources menu are shown only when multiple sensors providing the same
data are available to the system.
2 Select a data category.
3 Select a source.
Detailed Configuration Settings
Although all of the configuration is typically completed automatically through wizards, you can manually adjust
any setting to fine-tune the autopilot.
NOTE: Depending upon the configuration of the autopilot, certain settings may not appear.
NOTE: Each time you change the Speed Source setting, you must review the Low RPM Limit, High RPM Limit,
or Max. Speed settings, where applicable, and you must perform the autotune procedure again (Performing the
Autopilot Tuning Settings
On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation
Setup > Autopilot Tuning.
Accel. Limiter: Allows you to limit the speed of autopilot-controlled turns. You can increase the percentage to
limit the turn rate, and decrease the percentage to allow a higher turn rate.
Speed Source Settings
On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation
Setup > Speed Source Setup.
Speed Source: Allows you to select the speed source.
Low RPM Limit: Allows you to adjust the lowest RPM point of your boat. If the value does not match the value
on the helm control or chartplotter, you can adjust the value.
High RPM Limit: This setting should be 6000 RPM.
Max. Speed: Allows you to enter the maximum speed of the boat when powered by the kicker motor only.
Rudder Gain Settings
NOTE: If you set these values too high or too low, the autopilot may become overactive, attempting to
constantly adjust the heading at the slightest deviation. An overactive autopilot can cause excess wear on
the pump and drain the battery at a faster-than-normal rate.
On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation
Setup > Autopilot Tuning > Rudder Gains.
Gain: Allows you to adjust how tightly the rudder holds a heading and makes turns.
Counter Gain: Allows you to adjust how tightly the rudder corrects turn overshoot. If you set this value too low,
the autopilot can overshoot a turn when attempting to counter the original turn.
7
Steering System Settings
On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation
Setup > Steering System Setup.
Steering Dir.: Sets the direction the rudder must move to turn the vessel to port and to starboard. You can test
and reverse the steering direction if necessary.
