Reactor™ 40 electronic steering pack for Yamaha® Helm Master™ without GHC™ 20

This is an advanced autopilot system from Garmin, specifically designed to integrate with Yamaha® Helm Master™ electronic steering systems. It uses Garmin’s 9-axis AHRS (Attitude Heading Reference System) technology to deliver superior heading-hold accuracy and compensate for vessel motion.

The Reactor™ 40 autopilot uses 9-axis AHRS (Attitude Heading Reference System) technology. This technology delivers superior responsiveness and heading-hold accuracy by compensating for vessel movements across all axes, minimizing trajectory errors even in demanding sea conditions.

No, this kit is a 'core pack' (central kit) and does not include the GHC™ 20 control display. It is intended for installations where an existing compatible Garmin multifunction display or GHC™ 20 is already used for autopilot configuration and control.

The Reactor™ 40 system outperforms traditional autopilot systems based on fluxgate compasses. With its 9-axis AHRS technology, it compensates for vessel movements on all axes, delivering superior responsiveness and heading-hold accuracy, which minimizes trajectory errors even in demanding sea conditions.

The Course Computer Unit (CCU) is the system's core and the primary sensor of the Reactor™ 40 autopilot. It is essential for autopilot operation, measuring the vessel's position and movement to maintain heading.

No, this Reactor™ 40 electronic steering kit is specifically designed to integrate with Yamaha® Helm Master™ electronic steering systems.

This kit is designed to be configured and controlled via a compatible Garmin multifunction display or an existing GHC™ 20 screen. The course computer unit (CCU) must be connected to the same NMEA 2000® network as the control display or compatible chartplotter.

Yes, the system is fully compatible with the NMEA 2000® network. The compass calculation unit (CCU) and the control display (or compatible chartplotter) must be connected to a NMEA 2000® network. NMEA 2000® cables and connectors are included to build a network if needed.

Yes, to use the autopilot advanced features, optional NMEA 2000® devices such as a wind sensor, a water speed sensor, or a GPS device can be connected to the NMEA 2000® network.

Yes, if RPM data is not available via the autopilot controller connection or the NMEA 2000® network, you can select GPS as the speed source. Garmin recommends using an external GPS antenna mounted with a clear view of the sky for reliable and accurate speed information.

Yes, if your autopilot controller connection provides RPM data, or if one or more NMEA 2000®-compatible engines are connected to the NMEA 2000® network, you can select the tachometer (Tach. - NMEA 2000 or Proprietary) as the speed source.

Yes, Garmin recommends that the autopilot system be installed by a qualified marine installer. Specific knowledge of hydraulic steering components and marine electrical systems is required for correct installation.

The CCU must be mounted on a rigid and stable surface, away from sources of magnetic interference. It is essential to keep it clear of items such as iron, powerful magnets, high-current cables, and pumps with intermittent operation. The best position is near the boat's center of rotation, on the centerline, lower in the boat, and slightly forward.

You can use a handheld compass to test a mounting location. Hold the compass at the intended location, then move it six inches to the left, right, above, below, in front of, and behind. If the compass needle moves more than three degrees, magnetic interference is present and a new location should be chosen.

The CCU cable, which connects the CCU to the steering system, is 3 meters (9 feet) long. This cable must not be cut. Extension cables are available if the CCU cannot be mounted within 3 meters of the steering system.

After installation, you must run a short configuration sequence, which includes the Dockside Wizard and the Sea Trial Wizard. These assistants guide you through the steps required to configure and tune the autopilot to your boat's dynamics.

The sea trial assistant must be performed in calm water. The boat must not pitch at rest or at very low speed, and must not be significantly affected by wind. The weight on board must remain balanced, and it is recommended not to move around in the boat during the procedure.

Les outils nécessaires incluent :

Des tournevis Phillips et platsDes serre-câblesDes connecteurs de fils étanches (ou gaine thermorétractable et pistolet thermique)Du mastic marinUne boussole portable (pour tester les interférences magnétiques)Une perceuse et des foretsDes coupe-fils/dénudeursDes vis de montage sont fournies pour les composants principaux.

The alarm must be mounted near the main helm station. It can be installed under the dashboard. The alarm wires can be extended if necessary using 28 AWG (0.08 mm²) wire.
