Garmin Reactor 40 SBW Yamaha w/o GHC corepack
The Garmin Reactor 40 Steer-by-Wire (SBW) corepack for Yamaha is an autopilot system built specifically to integrate with Yamaha's Helm Master steer-by-wire outboard control, letting the boat hold a heading, follow a route, or execute automated manoeuvres without a traditional mechanical or hydraulic autopilot drive. 'w/o GHC corepack' means this particular package ships as the core autopilot electronics only, without a bundled GHC glass helm control display — it's intended for an installation where an existing GHC unit (or the boat's Garmin chartplotter acting as the control interface) is already in place.
At the heart of the system is Garmin's Course Computer Unit (CCU), which uses a solid-state 9-axis AHRS (Attitude and Heading Reference System) — combining gyroscopes, accelerometers, and magnetometers — so it can be mounted almost anywhere in almost any orientation and still maintain accurate heading data, unlike older fluxgate-compass-dependent autopilots. The CCU housing is fully gasketed and rated IPX7 waterproof, measures roughly 3-19/32 inches in diameter, weighs about 5.6oz, and operates across a 5°F to 131°F temperature range. It connects to the boat's NMEA 2000 network (9-16V input, NMEA 2000 LEN of 3 / 150mA draw) and can be controlled from up to three GHC helm units. Autopilot functions include heading hold, wind hold for sailors, tack/jibe manoeuvres, and step turns, giving hands-free control for long runs, trolling, and precise course-keeping around obstacles.
