Reactor™ 40 Steer-by-wire Standard Corepack

This corepack works with SeaStar Optimus systems, Yanmar Marine ZT370 sterndrive electronic power steering systems and ZF 2800 Pod drives. It requires a compatible Garmin chartplotter.

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.

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.

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.
