Compact Reactor 40 Hydraulic Autopilot Starter Pack

Engineered specifically for vessels measuring less than 25 feet in length, the entry-level Compact Reactor 40 hydraulic autopilot system provides the additional assistance required, enabling you to navigate and discover idyllic destinations with complete peace of mind.

Corepack Compatibility
This corepack is an ideal autopilot solution for single-engine outboard boats that are less than 25 ft long. It provides relief from manually holding the wheel to maintain course, especially when cruising at moderate to high speeds2.

Solid-State 9-Axis Ahrs
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.

Simple Calibration and Installation
All autopilots require commissioning and calibration. Reactor 40 makes it quick and easy. This autopilot is easy to install with flexible mounting options.

Wireless Remote Capabilities
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).

Shadow Drive™ Technology
Gain more freedom when maneuvering your boat. This corepack allows for optional Shadow Drive technology to automatically disengage the autopilot when you turn the wheel.
