The picks at a glance
Which one should you buy?

- For a kicker motor setup: For a powerboat with a kicker motor, the Garmin Reactor 40 Kicker Autopilot w/GHC 50 names the control head in the box, which suits an owner who wants the head included. See pick 2
- For a steer-by-wire helm: If your boat has an electronic steer-by-wire helm, the Garmin Reactor 40 Autopilot Steer-By-Wire Standard with GHC50 Control names the control head in the box, which is a key detail for that steering type. See pick 3
- For an owner who already has a drive: If you already have a drive aboard, a core pack like the Garmin Reactor 40 Corepack With GHC50 Control names the control head but not the drive, so you can add it separately. See pick 5

How we picked
This guide draws from a pool of 18 Garmin autopilot listings. The picks are ranked by a rule: first, listings whose title names both the drive and the control head in the box (or a tiller pilot with its built-in keypad), then those that name one of the two, then those that name neither. Inside each tier, picks follow the order in the pool file. The autopilots are compared on stated details and live prices, never on popularity or price ranking. The top pick is the only one with both drive and control head named, and the list keeps a spread across the Garmin Reactor 40 line.
How to choose
Start with the steering you already have
The first decision is matching the autopilot to your boat's own steering. The listings state the steering type in the title, such as hydraulic, mechanical, steer-by-wire, or kicker motor. Confirm that the unit you are looking at is sold for the steering your boat has, and read the listing for the full contents.
Sail or power
Some listings state the boat type in the title, such as power for kicker motor units. Tiller and wheel pilots are cockpit units for sailboats, but none of the Garmin picks here state a sailboat type. If the boat type is not stated by the seller, do not guess it; check the maker's page or the listing for more details.
Complete pack or core pack
A complete pack names the drive in the box, such as the SmartPump v2 for hydraulic steering. A core pack does not include the drive, which suits an owner who already has a drive aboard or needs to choose one for the boat's steering. Read the listing to see exactly what is in the box, because the title may not name every part.
Control head in the box or bought separately
Some listings name the control head in the box, such as the GHC 50 or GHC50. Others do not, which means the control head is bought separately. If the control head is not stated by the seller, do not assume it is included; check the listing for the contents.
Reading the model line
All the picks here are from the Reactor 40 line, which is a name on the listing. The model line tells you the family of the unit, but it does not tell you which steering type or which parts are included. Compare the stated details of each listing to see the differences.
What this guide leaves out (and why)
This guide compares autopilots on stated details and live prices only. It does not say which boat size or sea state an autopilot handles, because the catalogue has no data for those. For questions about fit, installation, or compatibility, check the maker's page and consult a qualified installer.
Questions
Does this guide say which boat size or sea state an autopilot handles?
No. The catalogue has no data for boat size, displacement, or sea state, so this guide does not guess. The listings state only the steering type, boat type, drive, control head, and model line. For fit questions, check the maker's page and consult a qualified installer.
What does it mean when the drive is not included in the box?
A core pack does not include the drive, which is the part that connects to your boat's steering. This suits an owner who already has a drive aboard or needs to choose one for the boat's steering. Read the listing to see exactly what is in the box, because the title may not name every part.
How do I know if the control head is included?
Some listings name the control head in the title, such as the GHC 50 or GHC50. If the control head is not stated by the seller, do not assume it is included. Check the listing for the contents, and if it is still unclear, contact the seller or consult the maker's page.
Can I use a hydraulic autopilot on a steer-by-wire boat?
The listings state the steering type in the title, such as hydraulic or steer-by-wire. A unit sold for hydraulic steering is not stated to work with steer-by-wire, and vice versa. Match the autopilot to your boat's steering, and confirm with the listing and the maker's page.
What does the model line Reactor 40 tell me?
The model line is a name on the listing, and all the picks here are from the Reactor 40 line. It tells you the family of the unit, but it does not tell you which steering type or which parts are included. Compare the stated details of each listing to see the differences.
