The Garmin Reactor 40 Hydraulic Corepack with SmartPump v2 is an autopilot system designed for powerboats and sailboats. The solid-state 9-azis Attitude Heading Reference System (AHRS) mounts in any direction and minimized heading error, course deviation, rudder movement and power consumption. It reacts to sea conditions to hold it's course, even when the boat is pitching and rolling. The SmartPump v2 will work with most boats and features a brushless motor for long life and reduced power consumption, and a compact footprint with simple color-coded connectors for quick install. The Reactor 40 with SmartPump v2 also automatically adjusts the maximum flow rate for a particular boat from 0 to 2.4 L per minute.

The GRM00705-79 autopilot system 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. When connected with any Garmin chartplotter it enables MARPA and chart overlay. Other features include Intelligent Rudder Rate Technology (IRRT) which slows or speeds the rudder rate based on boat speed for safety and performance as well as Shadow Drive Technology that automatically disengages the autopilot if the helm is turned and then automatically re-engages when a steady course is held.
