Type 0.5 12V Hydraulic Pump

The Raymarine Type 0.5 (12V) hydraulic pump is the perfect solution for smaller powerboats and yachts with hydraulic steering. With its compact design and robust construction, it provides smooth and precise rudder control, integrating seamlessly with Raymarine autopilot systems. This pump is reversing, meaning it drives fluid in both directions to steer port and starboard. With a flow rate up to 1000 cc/min, the Type 0.5 rapidly delivers hydraulic fluid to the cylinder, ensuring an immediate autopilot response for course corrections. Its maximum stall pressure (~50 bar / 750 psi) allows steady steering without straining the system.

It is designed for steering cylinders with approximately 50 cc to 110 cc volume (3 – 7 in³), covering small hydraulic setups – for example, fishing boats, speedboats, and RIBs with outboard engines up to ~150 HP, as well as small inboard-powered yachts. The Type 0.5 pairs with the ACU-100 actuator control unit (part of the Evolution EV-100 autopilot series) and is a top choice for boat owners seeking autopilot steering at an affordable cost with reliable performance.

• Ideal for small and mid-sized powerboats with a single hydraulic ram, where larger pumps would be overkill
• Recommended for upgrading a boat with an autopilot – the Type 0.5 provides the needed power without overloading the electrical system (average draw ~24 W)
• Compatible with the Raymarine Evolution EV-100 Hydraulic autopilot pack – a perfect match for boats around 20–30 feet in length
• High-quality build and marine-grade materials ensure a long service life for the pump
• Compact form factor simplifies installation in tight spaces near the engine compartment or helm
