Garmin Reactor 40 Steer-By-Wire Corepack f/Viking w/o GHC 20
Garmin Reactor 40 Steer-By-Wire Corepack f/Viking w/o GHC 20 — Product description
Discover the pinnacle of marine autopilot performance tailored specifically for Viking yachts equipped with VIPER steering systems. The Garmin Reactor 40 Steer-By-Wire Corepack delivers unmatched responsiveness, allowing captains to navigate open waters with confidence and ease. Engineered for powerboats that demand precision, this system transforms how you handle long offshore runs, tournament fishing trips, or leisurely cruises, keeping your vessel steady even in challenging sea states.
Advanced Solid-State 9-Axis AHRS Technology
At the heart of the Reactor 40 lies its innovative solid-state 9-axis Attitude Heading Reference System (AHRS). Unlike traditional gyro-based sensors prone to drift and bulkier installations, this compact unit can be mounted almost anywhere on your Viking yacht—in any orientation—without compromising accuracy. The result? Drastically reduced heading error, smoother course holding, fewer rudder adjustments, and optimized power draw. Passengers enjoy a more comfortable ride with less helm feedback, while you focus on the horizon.
Adaptive Response to Real-World Conditions
What sets this autopilot apart is its ability to anticipate and react to dynamic sea conditions. Whether your Viking is pitching through head seas, rolling in beam swells, or carving through crosswinds, the Reactor 40 maintains your intended track with minimal deviation. It intelligently adjusts steering inputs to counteract waves and currents, providing a level of stability that feels almost intuitive. Boaters report it excels during those grueling all-day troll patterns or when pushing through rough inlets, saving wear on both crew and equipment.
Effortless Setup for Quick Time on the Water
Time is precious on the water, so we've streamlined the commissioning and sea trial calibration to be remarkably straightforward. No endless shadow drives or complex alignments—just a few intuitive steps via your compatible Garmin chartplotter, and you're ready to go. This user-centric design respects the busy schedules of Viking owners who prioritize reliability over fuss.
Versatile Modes for Powerboat and Sailing Enthusiasts
- Heading Hold: Locks in your desired direction effortlessly.
- Wind Hold: Ideal for sail-assisted power setups.
- Tack/Jibe Automation: Simplifies maneuvers.
- Step Turns: Precise radius control for fishing patterns.
- Trolling Patterns: Customizable grids and spirals for bait deployment.
Seamless Integration with Your Viking's Garmin Ecosystem
Designed without the GHC 20 display for a cleaner install, this corepack thrives when networked with your existing Garmin chartplotters. Control everything from the helm station, flybridge, or even remotely via compatible MFDs. Unlock advanced capabilities like automated GPS path following when paired with BlueChart charts—perfect for plotting safe routes around shoals or staging grounds. It communicates flawlessly over NMEA 2000, sharing data with radar, sonar, and engine monitors for a unified boating experience. Viking yachts with VIPER steer-by-wire systems benefit from native compatibility, ensuring plug-and-play harmony with factory electronics.
Built for Endurance and Viking Toughness
Garmin's Reactor 40 is ruggedized for the demanding marine environment, with IPX7 waterproofing on key components and robust cabling to withstand salt spray, vibrations, and years of heavy use. Lower power consumption means longer runtime on battery banks during generator-off anchoring, a boon for extended adventures. It's not just an autopilot; it's an investment in safer, more enjoyable voyages aboard your Viking.

Frequently Asked Questions
What makes the Garmin Reactor 40 ideal for Viking yachts with VIPER steering?
It's specifically engineered for Viking's VIPER steer-by-wire systems, offering native compatibility, precise control without mechanical linkages, and responsive performance optimized for larger powerboats.
Do I need a separate autopilot display with this corepack?
No, this corepack excludes the GHC 20 for a streamlined setup. Control it fully through compatible Garmin chartplotters over NMEA 2000.
How does the 9-axis AHRS improve over older autopilot sensors?
The solid-state 9-axis AHRS provides superior stability with no moving parts, flexible mounting options, and reduced errors in heading, course, and power use compared to traditional gyros.
Is calibration complicated for the Reactor 40?
Not at all—commissioning is quick and guided via your chartplotter, typically completed in under an hour with minimal sea trial time.
Can this autopilot handle rough seas on a Viking?
Absolutely. It dynamically reacts to pitch, roll, and yaw, holding course tightly even in swells, which is crucial for Viking owners chasing billfish offshore.
What boating modes does it support?
Powerboat essentials like heading hold and step turns, plus sailing features such as wind hold, tacks, and jibes for versatile use.
How does it integrate with other Garmin marine electronics?
Via NMEA 2000 networking, it shares data with chartplotters, radar, and fishfinders, enabling features like Auto Guidance for path steering.

The 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
Reactor 40 for Viking VIPER steering systems brings our leading-edge marine autopilot technology to Viking yachts. 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 new 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.
