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. Experience the ultimate
hydraulic autopilot performance when paired with the one-size-fits-most,
high-reliability, brushless SmartPump v2.
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
You have full control of Reactor 40 from the chartplotter display. Combined
with a compatible Garmin networked chartplotter and BlueChart® g2
Vision® charts, you can enjoy optional features such as Auto Guidance1,
which automatically steers GPS paths.
One SmartPump v2 Is the Easy Solution
The Reactor 40 autopilot with SmartPump v2 puts an end to guessing which
pump size will work with your particular boat. One SmartPump v2 works for most
boats; for optimum control and confidence, you’ll know you have the right pump
for your boat. Plus, you get complete control in a smaller size with better
thermal performance, higher reliability and lower power consumption. It also
includes color-coded connectors to make it very easy to install. Pretty smart.
Limit the Maximum Flow Rate
Reactor 40 with SmartPump v2 automatically adjusts the maximum flow rate
for a particular boat from 0 to 2.4 L per minute. It also uses a brushless
motor, which provides increased reliability, longer pump life, reduced power
consumption, quiet operation, a smaller package, improved thermal performance
and higher efficiency.
Eliminate Risk of Rudder “Hard Over”
The Reactor 40 autopilot with SmartPump v2 is a complete autopilot package.
SmartPump v2 is a single integrated unit comprised of a motor drive circuit
with the pump in a single assembly. Equipped with Intelligent Rudder Rate
Technology (IRRT), it slows the rudder rate when the vessel is at high speeds
and speeds up rudder rate when the vessel is at lower speeds to provide
optimal performance and safety in all conditions. The brushless motor drive
eliminates the risk of rudder “hard over” due to hardware or software
Enjoy a Longer Lasting System
Boating environments are harsh, especially on saltwater. So our SmartPump
v2 is protected from the elements. SmartPump v2 is engineered from
corrosion-resistant components, including anodized aluminum and nickel-plated
Experience Advanced Autopilot Technology
When you have a Reactor 40 with SmartPump v2 aboard your boat, you can have
control 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 Guidance¹, which
automatically steers GPS paths.
Stay in Control with Shadow Drive Technology
The Reactor 40 with SmartPump v2 features patented Shadow Drive technology.
This gives you the security of knowing you maintain control, even when the
autopilot is engaged. The Shadow Drive system automatically disengages the
autopilot if the helm is turned, giving you the freedom to maneuver the boat.
The autopilot automatically re-engages when you hold a steady course.
Connect to Networked Devices
The Reactor 40 autopilot with SmartPump v2 for hydraulically steered boats
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 GHC using a compatible quatix® 3 or quatix 5 marine multisport
Add Even More Peace of Mind
Add an optional GRF™ 10 rudder feedback sensor, and you can further enhance
the performance of your Reactor 40 autopilot with SmartPump v2.
¹Auto Guidance is for planning purposes only and
does not replace safe navigation operations.
The GHC 20 autopilot helm controller is compatible with newer
Garmin autopilots as well as legacy models on both power and sail vessels.
It's large, bright 4-inch color display is easy to read at a
distance and 170 degree viewing angle. Glass-bonded anti-glare lens prevents
fogging and increases contrast. Daylight readability is enhanced with a
high-contrast color scheme. For enhanced night visibility, you have a choice
of red/black, green/black or the normal night mode color scheme along with a
