Kicker Motor Autopilots: Setup and Use

What is a kicker motor autopilot?

A kicker motor is a small auxiliary outboard engine, often used on fishing boats for trolling or as a backup. A kicker motor autopilot is a system that automatically steers that motor to maintain a heading, so you can focus on fishing or other tasks without holding the tiller or wheel.

Unlike a main engine autopilot that connects to the boat's primary steering, a kicker autopilot typically uses a dedicated drive unit that attaches to the kicker itself. This allows the autopilot to control the kicker independently, which is useful when trolling at slow speeds where the main engine may not be in use. For a broader look at autopilot systems, see the best marine autopilot guide.

• The drive unit is the part that physically moves the kicker's steering.
• The control head lets you set and adjust the desired heading.
• A heading sensor or compass tells the system which way the boat is pointing.
• The course computer processes the sensor data and sends commands to the drive.

How kicker autopilots steer the motor

Kicker autopilots steer by moving the kicker motor's steering mechanism. There are two common ways they do this: through a tilt tube or through a linkage. A tilt tube is a hollow tube that runs through the motor's mounting bracket, and a linkage connects the drive to the motor's steering arm.

The drive unit, which can be a linear actuator or a rotary drive, pushes or pulls the steering mechanism based on commands from the autopilot. The system continuously adjusts to keep the boat on the heading you set, compensating for wind and current.

When reading a listing, look for words like 'tilt tube' or 'linkage' to understand how the drive connects. The maker's page will specify which steering types the drive supports, so always check that before buying. If you are comparing drive types, our drive types explained article can help.

What is in a kicker autopilot pack?

A kicker autopilot pack typically includes the drive unit, a control head, a heading sensor, and the necessary cables. Some packs may also include a rudder reference unit, which tells the autopilot the position of the motor, though some systems use software to estimate this.

For example, Furuno's NavPilot 300 uses 'Fantum Feedback' to eliminate the need for a physical rudder feedback unit on outboard installations, simplifying the setup. This is a feature to look for if you want a cleaner installation.

The pack may or may not include the control head. Some listings are 'core packs' that omit the control head, while others are 'complete packs' that include everything. Check the listing details to see what is in the box. For more on this distinction, see our core pack vs complete pack article.

Choosing a kicker autopilot for your boat

The first step is to identify your kicker motor's steering type. Is it tiller-steered, or does it have a remote steering system? The drive unit must match that steering type, so check the maker's specifications.

Consider how you use the boat. If you troll at slow speeds, look for a system with features like Sabiki mode, which maintains heading while drifting astern, or speed control that adjusts engine RPM to keep a constant speed. These are described on the maker's pages.

Also think about integration. Many autopilots connect to a NMEA 2000 network, allowing them to share data with chartplotters and other instruments. This is useful for route following and other advanced features. Learn more in our NMEA 2000 connectivity article.

Finally, decide whether you want a complete pack or a core pack. If you already have a compatible control head, a core pack might save money. If not, a complete pack is simpler to install. See our best complete autopilot packs and best autopilot core packs guides.

Installation considerations

Installing a kicker autopilot involves mounting the drive unit, connecting it to the steering, and wiring the control head and sensor. This is not a simple task and requires following the maker's manual carefully. A qualified installer can ensure the system is set up correctly.

Before installation, check the space around the kicker motor. The drive unit needs room to move without interfering with other components. Also, consider the power supply: most autopilots run on 12-volt systems, but some may accept 24 volts, as noted in the specifications.

Ask your installer about the rudder reference. Some systems need a physical unit, while others use software like Fantum Feedback. This affects the installation complexity and the parts needed. For more on installation planning, see our retrofit considerations article.

Using a kicker autopilot on the water

Once installed, using a kicker autopilot is straightforward. You set a heading on the control head, and the system steers the kicker to maintain it. Many systems have modes for fishing, such as Sabiki mode for drifting astern or FishHunter mode for circling a target.

Always keep a lookout. An autopilot does not replace the need for a watch, as the U.S. Coast Guard Boating Safety page emphasizes the importance of safe boating practices. The autopilot is a tool to assist you, not a substitute for attention.

If the system has a remote control, you can adjust the heading from anywhere on the boat, which is handy when fishing from the stern. Some remotes use Bluetooth and work within a certain range, as described in the product details.

Questions to ask before buying

Before you buy a kicker autopilot, ask the seller or dealer these questions:

What steering types does the drive unit support? Does the pack include the control head? Is a rudder reference unit required, or does the system use software feedback? What is the power requirement? Does the system connect to NMEA 2000?

These answers will help you compare listings on stated details and choose the right system for your boat. The maker's page is the best source for this information. For a curated list of options, see our best kicker motor autopilots guide.

What to pick for your situation

Questions

What is a kicker motor autopilot?

It is an autopilot system that steers a small auxiliary outboard motor, often used for trolling or low-speed maneuvering. It uses a drive unit connected to the kicker's steering to maintain a set heading.

How does a kicker autopilot attach to the motor?

It attaches either through a tilt tube or a linkage, depending on the drive unit and the motor's steering design. The drive moves the steering mechanism to control the direction.

Do I need a rudder reference unit?

Some systems require a physical rudder reference unit, while others use software like Furuno's Fantum Feedback to estimate the motor's position. Check the maker's specifications.

Can I use a kicker autopilot with my existing control head?

If you have a compatible control head from the same brand or one that works with the system, you can buy a core pack without a control head. Otherwise, a complete pack is simpler.

Is a kicker autopilot difficult to install?

Installation involves mounting the drive, connecting to steering, and wiring. It requires following the maker's manual and may need a qualified installer. It is not a simple plug-and-play task.
