Upgrade your boat's steering with the reliable performance of the Pump-3 hydraulic reversible pump, designed specifically for seamless integration into autopilot systems. Ideal for vessels up to 50 feet, this 12V DC pump delivers moderate flow rates to handle cylinder displacements from 9.8 to 33.5 cubic inches (160-550 cc), ensuring smooth and precise maneuvering on the water.

Engineered for Marine Autopilot Excellence

Crafted by Navico, a leader in marine electronics, the Pump-3 steps in as the modern successor to the trusted RPU160. Its reversible design allows for effortless direction changes, making it a go-to choice for boaters seeking dependable hydraulic steering without the hassle of constant manual adjustments. Whether you're cruising coastal waters, fishing offshore, or navigating tight marinas, this pump provides the hydraulic power needed for responsive autopilot operation.

Standout Features That Deliver Real-World Results

• Reversible Operation: Easily switches direction for full autopilot control, reducing wear and enhancing efficiency.
• Moderate Flow Rate: Optimized at 1600 cc (98 cu.in) per minute to balance speed and precision for mid-sized boats.
• 12V DC Power: Compatible with standard marine electrical systems, drawing power reliably from your boat's battery setup.
• Versatile Displacement Range: Handles rams from 160-550 cc (9.8-33.5 cu.in), perfect for a wide array of hydraulic cylinders.
• Compact and Durable Build: Engineered to withstand harsh marine environments, including saltwater exposure and vibrations.

Why Boaters Trust the Pump-3 for Superior Steering

Unlike basic pumps that falter under load, the Pump-3 maintains consistent pressure and flow, minimizing hydraulic fluid leaks and extending system life. Paired with compatible autopilot computers like the NAC-3 or AC42, it transforms your helm into a smart, hands-free system. Boaters report fewer corrections needed during long passages, leading to less fatigue and safer voyages. Its moderate flow prevents over-pressurization in smaller rams while packing enough punch for larger setups up to 33.5 cu.in.

In real boating scenarios, this pump shines during autopilot tracking in choppy conditions. The reversible gear mechanism ensures quick response times, helping you hold course against wind and current—essential for trawlers, sportfishers, and sailboats in this size class.

Seamless Compatibility and System Integration

The Pump-3 integrates effortlessly with Navico's ecosystem, including Simrad and B&G autopilot packs. It requires an autopilot computer for operation, creating a plug-and-play solution for retrofits or new installs. Matches perfectly with hydraulic rams in the specified range, supporting everything from balanced cylinders to those with heavier tiller loads.

Practical Tips for Optimal Performance

To maximize longevity, mount the pump in a dry, ventilated area away from bilge water. Regularly check hydraulic fluid levels and bleed the system after installation to eliminate air pockets. This proactive approach keeps steering crisp and prevents common issues like sluggish response in rough seas.
