Autopilot drive units, under the control of the course computer, actually apply the steering corrections to your boat's steering system. The first step in selecting a Raymarine SmartPilot autopilot is selecting the proper drive unit for your vessel. You will need to determine the type of steering system you have installed in your vessel. Raymarine SmartPilots accommodate virtually all steering systems: hydraulic, mechanical and power assisted stern drive steering systems.Drive units for mechanically steered boats are matched to the vessel's actual displacement (dry displacement plus 20%). Drive units for mechanically steered vessels are available in three styles:
Mechanical Linear Drives - attached to a tiller arm on the rudder; the most common unit used on sailboats; powerful, short throw, quiet
Other drives (including for stern drive steering) and accessories are available - please call
All units are 12 volts
