Reactor 40 Steer-by-wire Corepack for Yamaha Helm Master

** Not compatible with Helm Master EX **

Garmin's Most Responsive Autopilot System on the Water

  • Solid-state 9-axis Attitude Heading Reference System (AHRS)
  • Minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride
  • Minimal commissioning and calibration

The Reactor 40 for steer-by-wire provides robust autopilot capabilities for Yamaha Helm Master systems. 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.

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 system greatly minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride for all on board.

Reacts to 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 and 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 a compatible Garmin 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.

Connect to Networked Devices

The Reactor 40 autopilot is operated using up to 3 GHC helm control units. GHC communicates with the autopilot system via your NMEA 2000 network, so autopilot heading data can be shared easily with other devices. This enables MARPA and chart overlay when connected to a Garmin chartplotter. An optional handheld wireless remote control is also available; however, for the highest level of convenience, control the using a compatible quatix 3 or quatix 5 marine multisport smartwatch.

The GHC helmet control unit is used to control the reactor 40. The control unit communicates with the autopilot system through the Nmea 2000 bus, so the autopilot heading data can be easily shared with other devices. When connected to a Garmin plotter, this will enable Marpa and chart overlays. Up to three GHC controllers can be connected to a single reactor 40. There are complete kits designed for motor boats and sailing boats. Reactor 40 is used in conjunction with a compatible networked chartplotter to provide full control no matter where you are on the ship. In addition to keeping the heading out in almost all weather and wind conditions, the system can also smoothly execute various pre-programmed trolling and search procedures. The Reactor 40 autopilot is very versatile. All core components provide motorboat and navigation functions, including heading keeping, wind keeping, tack/jib, turning, etc.
