Raymarine ACU-400

Electric rotary autopilot drive for vessels up to 11,000 kg (24,000 lbs.) displacement

Autopilot Rotary Drive Overview
Autopilot rotary drives are designed for power and sailboat systems that can be driven from the helm position through a chain and sprocket. Typically this applies to cable and rod-steering type systems. 
The outstanding design of the rotary drive unit provides smooth, powerful autopilot steering with quiet operation.
Optional drive sprockets and modifications to the boat's steering chain system may be required. Please consult with your local Raymarine Authorized Dealer or product support for more details.
Raymarine offers rotary drive units for 12 or 24-volt power systems and in Type 1 or Type 2 configurations to fit a wide range of vessel displacements.
