Designed for powerboats, the Reactor 40 hydraulic autopilot corepack with SmartPump gives you the steering assistance you need, leaving you free to explore paradise without worry. The Reactor 40 corepack is the ideal complement to your boat's hydraulic steering system. It features a solid-state 9-axis AHRS, meaning it can be mounted virtually anywhere. Even when the boat bounces and rocks, the autopilot adapts to sea conditions to maintain course. Can't wait to get underway? No problem, we've made the calibration process quick and easy. That's the Power of Simple. Use it with a compatible Garmin chartplotter and control the autopilot from anywhere on the boat. Want more? The optional GHC™ 50 autopilot instrument optimizes the autopilot experience.
