M81203 Type 3/24V Hydraulic Linear Drive Unit (Raymarine Autopilot)

The Raymarine Type 3 hydraulic linear drive (24V) delivers reliable autopilot steering for large vessels with mechanical steering systems. It is rated for boats up to 35,000 kg displacement and operates on a 24-volt DC supply. This self-contained system comes complete with a hydraulic ram, 24V pump, reservoir, and mounting hardware, all pre-configured for installation. The drive mounts securely to the vessel and connects to the rudder via an independent tiller arm. The 24V power operation provides rapid response and high thrust output, well-suited for heavier ships.

Use cases and recommendations:

• Heavy yachts and workboats: ideal for large sailing yachts and heavy motor vessels that demand a powerful autopilot for long voyages and open-sea navigation
• Optimal integration: pair with the Raymarine ACU-400 control unit to ensure sufficient drive power and seamless integration with Evolution autopilot electronics
• 24V system efficiency: the 24-volt pump reduces current draw and can handle longer cable runs, making it advantageous for big boats with 24V power systems
• Easy override: the built-in clutch allows quick reversion to manual helm with no resistance, critical for docking maneuvers or emergency steering situations
