Important Safety Information
WARNING
See the Important Safety and Product Information guide in the
product box for product warnings and other important
information.
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
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.
Failure to install and maintain this equipment in accordance with
these instructions could result in damage or injury.

Parts Identification
The throttle actuator is the component of the Reactor 40 Kicker
autopilot system that controls the speed of the motor.
You must install the throttle actuator inside the motor housing
and connect it to the carburetor throttle lever using the linkage
parts supplied in this package. Different motor types require
different linkage parts, and the parts are separated into separate
bags. These instructions refer to the labels on the bags when
discussing the parts needed for different motor types.

Installation Preparation
Mounting and Connection Considerations
When preparing to install the throttle actuator, observe the
following considerations:
• You must install the throttle actuator inside the motor
housing.
• Most motors use a throttle linkage to control the carburetor
throttle lever. You should replace the factory-installed throttle
linkage with the provided throttle linkage to prevent the
throttle actuator from back-driving the throttle on the tiller
(Tiller Back Drive Considerations, page 1).
• You must secure the throttle cable to the motor manifold and
connect it to the carburetor throttle lever on the motor using
the included bracket and linkage specific to your motor type.
• You can place the throttle actuator box in any available space
inside the motor housing after you secure the throttle cable to
the manifold and route the other cables. You can use the
included large zip ties to secure the throttle actuator box
inside the motor housing to keep it from moving during use.
• You must secure the RPM cable to the outside of a spark
plug cable (Connecting the RPM Cable, page 5).
• You must connect the throttle actuator to the ECU of the
autopilot system using the provided cable run from inside the
motor housing (Connecting the Throttle Actuator to the ECU,
page 6).
Tiller Back Drive Considerations
Most motors use a throttle linkage to control the carburetor
throttle lever. This linkage opens and closes the carburetor
when you adjust the throttle on the tiller arm. Because the
autopilot throttle actuator controls the speed of the motor from
inside the motor housing, you should replace the factoryinstalled throttle linkage with the provided throttle linkage. This
prevents the throttle actuator from back-driving the throttle on
the tiller arm, but still allows you to use the throttle on the tiller
arm when you are not using the autopilot system to control the
motor.
See the connections diagram for your motor type to locate the
existing throttle linkage and replace it with the included linkage.
August 2019
190-02451-94_0B
NOTE: Because of the motor design, you cannot replace the
throttle linkage on Honda motors. Under typical operation, the
throttle actuator back-drives the throttle on the tiller arm on
Honda motors, and you must adjust the friction collar on the
throttle to allow the actuator to control the speed of the motor
(Adjusting the Throttle Friction, page 5).
Assembling the Carburetor Linkage
The carburetor linkage allows the throttle cable from the actuator
to pull open the carburetor throttle lever on the motor.
1 Remove the carburetor linkage arm from the bag
containing the parts for your motor.
2 Remove the carburetor linkage bracket
from the bag
containing common parts .
3 Using the bolt and nut in the bag containing common parts,
connect the carburetor linkage bracket to the carburetor
linkage arm on the tapered end of the arm.
Tighten
the nut so the bracket is securely connected to the
4
arm, but loose enough so the bracket moves freely.

Connecting the Throttle Actuator Cable to the
Carburetor Linkage
The carburetor linkage is designed to hold the cable from the
throttle actuator securely. Because of the design, you must
connect the throttle actuator cable to the carburetor linkage
before you secure the parts to the motor.
1 If necessary, assemble the carburetor linkage (Assembling
the Carburetor Linkage, page 2).
2 Place the round end of the throttle actuator cable into the
hole on the end of the carburetor linkage.
3 Rotate the cable so it feeds through the slot on the end of the
linkage.

Common Installation Procedures
These procedures are the same for all motor models.
Securing the Throttle Actuator Cable to the Bracket
for Most Motor Types
Before you secure the cable to the bracket, you should connect
the end of the throttle actuator cable to the carburetor linkage
(Connecting the Throttle Actuator Cable to the Carburetor
Linkage, page 2).
NOTE: This type of bracket is used to secure the throttle
actuator cable for most motor types. If you are installing the
throttle actuator on a Mercury 15 through 20 horsepower motor,
you must follow the instructions for that bracket instead
(Securing the Throttle Actuator Cable to the Bracket for Mercury
15 through 20 Horsepower Motors, page 4).
1 Place the raised portion of the throttle actuator cable into
the bracket between the raised tabs .
Notes
You should connect the throttle actuator cable
to the carburetor linkage
before securing it
to the throttle cable bracket
(Connecting
the Throttle Actuator Cable to the Carburetor
Linkage, page 2).
Throttle cable You must secure the throttle actuator cable to
bracket
the throttle cable bracket using the included
zip ties (Securing the Throttle Actuator Cable
to the Bracket for Most Motor Types,
page 5).
2 Secure the cable to the bracket using the included zip ties
.
Connecting the RPM Cable
NOTICE
You must not cut or strip the RPM cable or the spark plug cable.
Cutting or stripping either cable will result in damage to the
throttle actuator, the motor, or both.
Manifold
mounting
location
You must loosen the existing bolt on the
manifold and slide the throttle cable bracket
into place .
You should not remove the bolt from the
manifold, because it is difficult to put the bolt
back in place after it has been removed.
The RPM cable monitors engine RPM, and is needed for proper
autopilot operation.
1 Route the RPM cable from the throttle actuator box to a spark
plug cable on the motor.
2 Secure the wrapped tip of the RPM cable to the outside of
the spark plug cable using the included zip ties.
Carburetor
linkage
You must assemble the carburetor linkage
before installing it (Assembling the Carburetor
Linkage, page 2).
The carburetor linkage arm is keyed to fit one
way on the carburetor only.
You must remove the existing lock washer to
install the carburetor linkage bracket, and you
should apply Loctite thread lock to the bolt
when securing the bracket.
3 Secure the RPM cable so that the wrapped tip of the cable is
Adjusting the Throttle Friction
the only part of the RPM cable that contacts the spark plug
cable.
Because the throttle actuator back-drives the tiller throttle on
Honda motors, you must adjust the throttle friction on the tiller
arm for the actuator to work properly.
1 Locate the friction collar on the tiller arm.
NOTICE
Routing the unwrapped portion
of the RPM cable
alongside the spark plug cable
may result in a lost RPM
signal and cause issues with the autopilot operation.

Connecting the Throttle Actuator to the ECU
After you connect the throttle actuator and linkages inside the
motor, you must connect the throttle actuator to the autopilot
ECU.
1 Locate the cable pass-through location on the motor.
This area is where the motor cables are routed from the
inside of the motor to the outside of the motor, and is usually
near the tiller arm.
2 If necessary, create a cable pass-through opening in the
motor housing for the ECU cable.
3 Route the ECU cable on the throttle actuator from the inside
of the motor to the outside of the motor.
4 Route the ECU cable to the location where you installed the
autopilot ECU, and connect it to the THROTTLE port.
5 If necessary, apply marine sealant to the cable pass-through
opening to protect the inside of the motor from water ingress.
Testing the Throttle Actuator Installation
Before you can test the installation, you must install all of the
autopilot components and all of the throttle actuator linkage
components, and connect the throttle actuator to the ECU.
1 Turn on the motor.
2 Turn on the autopilot system.
3 Engage the autopilot.
4 On the remote control, press to increase the throttle using
the throttle actuator.
The throttle actuator should move the throttle to full speed.
5 On the remote control, press to decrease the throttle using
the throttle actuator.
The throttle actuator should return the motor to idle.
6 Complete an action:
• If the throttle actuator does not move the throttle from full
speed to idle, adjust the throttle cable bracket and repeat
this test.
• If the throttle actuator controls the throttle correctly, turn
off the motor and the autopilot system.
