Imagine gliding across choppy waters without constantly adjusting the wheel— that's the freedom the Reactor 40 mechanical retrofit corepack delivers. Designed for boaters who demand precision and reliability, this system pairs perfectly with the GHC 50 autopilot instrument to transform your helm into a command center. Whether you're chasing fish offshore or cruising coastal routes, it holds your course steady, freeing you to focus on the adventure ahead.
Boat owners often struggle with autopilots that falter in rough seas or require complex setups. This corepack tackles those issues head-on with its innovative design, making it a favorite among serious mariners who value hands-free navigation.
At the heart lies a solid-state 9-axis AHRS (Attitude Heading Reference System), which senses motion in all directions. Unlike older magnetic compasses prone to interference, this gyro-stabilized sensor mounts almost anywhere on your vessel—upright, upside down, or sideways—without losing accuracy. It slashes power draw, cuts heading drift, and delivers razor-sharp course holding even as waves pitch and roll your boat.
Sea state changes? No problem. The system dynamically adjusts to keep you on track, supporting heading hold for straight-line precision, wind hold for sailboats, and step turns for smooth maneuvers. Pair it with a wind sensor, and unlock tack/jibe automation that feels intuitive, saving wear on your crew during long passages.
Calibration headaches are a thing of the past. The Reactor 40 streamlines commissioning into a few straightforward steps, getting you back on the water fast. It integrates with direct-drive, cable-actuated, or hydraulic steering systems, including optional solenoid setups. For hydraulic rams, add Shadow Drive for automatic disengagement when you grab the wheel—perfect for docking or quick evasions.
Flexibility extends to controls: Link multiple stations, remotes, or even quatix smartwatches via NMEA 2000, all managed from compatible Garmin multifunction displays.
The included GHC 50 touchscreen elevates your setup with a dedicated autopilot interface. Share data seamlessly with Garmin MFDs for a unified ecosystem. Access powerboat essentials like follow-route guidance or sailing-specific tools, all while enjoying the confidence of proven marine-grade durability.
"It's like having an extra crew member who never tires—precise, responsive, and always ready." – Feedback from offshore anglers.

Garmin Reactor™ 40 Mechanical/Retrofit/Solenoid Corepack With GHC™ 50 Autopilot Instrument
Model: 010-02794-02This corepack works with direct or cable-actuated steering systems to support heading hold, wind hold, step turns and tack/jibe modes.
With its advanced solid-state 9-axis AHRS, you can mount Reactor 40 nearly anywhere, in any orientation. It even reduces power consumption, minimizes heading error and more.
Hold your course on the sea — this autopilot reacts to conditions, so you can remain confident even when you’re pitching or rolling.
All autopilots require commissioning and calibration. Reactor 40 makes it quick and easy.
Gain more freedom when maneuvering your boat. On hydraulic installations, this corepack allows for optional Shadow Drive technology to automatically disengage the autopilot when you turn the wheel.
Choose between class A, class B compact or class B drive units for your steering system (sold separately). All Garmin linear drives include built-in rudder feedback sensing.
Control your autopilot from anywhere on your boat by using your compatible Garmin devices, including the Reactor autopilot remote, select quatix® marine smartwatches and more (requires a compatible Garmin chartplotter or GHC 50 autopilot instrument).
Combine the Reactor 40 corepack with the GHC 50 autopilot instrument to add a dedicated, touchscreen autopilot display to your helm. Plus, GHC 50 allows you to share data and settings with Garmin MFDs and other installed Garmin devices.
For even more peace of mind, add the GRF 10 rudder feedback sensor to further enhance your autopilot’s performance (requires GHC 50 autopilot instrument or compatible Garmin chartplotter).
When connected to your compatible Garmin chartplotter, all Reactor 40 corepacks offer powerboat and sailing features, including heading hold and step turns — plus wind hold and tack/jibe when paired with a wind sensor (sold separately). You can even gain additional benefits such as the follow route and Auto Guidance+™ features1.
