Imagine gliding across choppy waves with your boat holding a steady course, no constant wheel adjustments needed. The Garmin Reactor 40 Steer-By-Wire Standard Corepack delivers exactly that, transforming long voyages into effortless adventures. Tailored for modern electronic steering setups like SeaStar Optimus, Yanmar Marine ZT 370 stern drives, and ZF 2800 Pod drives, this system brings commercial-grade responsiveness to recreational boating.
Boat captains rave about its ability to cut down on fatigue during extended trips, whether you're trolling for fish, cruising coastal waters, or pushing through rough seas. By leveraging cutting-edge sensors, it anticipates and counters boat motion, keeping everyone aboard comfortable and on track.
At the heart of this autopilot lies a solid-state 9-axis Attitude Heading Reference System (AHRS). Unlike traditional gyros that demand precise orientation, this compact unit mounts almost anywhere on your vessel—in tight engine compartments or awkward angles—without compromising performance.
It slashes heading errors to near zero, smooths out course deviations, reduces unnecessary rudder activity, and optimizes power draw. The result? A serene ride that feels intuitive, even in unpredictable conditions, making it a game-changer for both powerboaters and sailors.
What sets this system apart is its proactive intelligence. It doesn't just follow a set path; it reads the ocean's rhythm—pitch, roll, yaw—and adjusts in real-time. Cross swells or beam seas? No problem. Your boat stays locked on course, freeing you to focus on navigation, fishing lines, or simply enjoying the horizon.
Versatile modes cater to diverse needs: maintain heading for straight-line cruising, hold wind angle for sailing precision, execute smooth tacks and jibes, or perform patterned turns for search patterns. Powerboat enthusiasts appreciate step turns for quick maneuvers, while sailors benefit from wind-based holding.
Time on the water is precious, so why spend hours calibrating? This corepack minimizes the hassle with intuitive commissioning that gets you up and running fast. Connect via NMEA 2000, run a brief sea trial, and you're steering by wire with confidence. It's designed for DIY-savvy boaters or pros alike, emphasizing reliability from the first voyage.
Pair it with your existing Garmin chartplotter over the network, and control is at your fingertips from helm or flybridge. Access trolling patterns for precise bait placement, shadow tracking for man-overboard scenarios, or Auto Guidance paths for plotted routes. It thrives in all weather, holding steady when winds howl or waves crash.
This integration elevates situational awareness, blending autopilot smarts with radar, sonar, and GPS for holistic command of your vessel.

Reactor 40 Steer-By-Wire Standard Corepack without GHC 20
The Most Responsive Autopilot System on the Water
Reactor 40 for steer-by-wire provides robust autopilot capabilities for SeaStar Optimus systems, Yanmar Marine ZT 370 stern drive electronic power steering systems and ZF 2800 Pod drives.
With a complete package designed for powerboats and sailboats, Garmin brings an advanced marine technology to the boating public that was once only available for commercial boats. The Reactor 40 autopilot series is simply the most responsive autopilot system we have ever offered.
Reactor 40 autopilots are very versatile. Both powerboat and sailing features are available in all corepacks, including heading hold, wind hold, tack/jibe, step turns and more; simply pick the autopilot that's compatible with your existing steering system.
Solid-state 9-axis AHRS
With its advanced solid-state 9-axis AHRS, you can mount Reactor 40 nearly anywhere, in any orientation. In addition, this new system greatly minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride for all on board.
Reacts to Sea Conditions
This amazing autopilot actually reacts to the sea to hold your course. Even when the boat is pitching and rolling, you can remain confident that the Reactor 40 autopilot will keep you on your desired course.
Minimal Commissioning & Calibration
All autopilots require commissioning and calibration all of them. We know you just want to get on the water, so we made this process as fast and easy as possible. That's the power of simple.
Full Integration with Garmin Chartplotters
Combined with our compatible networked chartplotter, you can have full control of Reactor 40 from wherever you are on the boat. In addition to holding its course in virtually all weather and wind conditions, the system can smoothly perform a variety of preprogrammed trolling and search procedures. Plus, with a compatible Garmin networked chartplotter and BlueChart g2 Vision charts (sold separately), you gain optional features such as Auto Guidance, which automatically steers GPS paths.
