Hydraulic Pump, RPU-300US 12V, 23-36 ci

Powerful Steering for Demanding Marine Conditions

Enhance your vessel's autopilot performance with this robust 12V hydraulic pump designed for cylinders displacing 23-36 cubic inches. Engineered for seamless integration into larger boats, it delivers consistent hydraulic pressure to ensure precise course-keeping even in rough seas or high-speed maneuvers. Boaters trust its reliable operation to maintain heading accuracy, freeing up the helm for other critical tasks during long passages.

Whether you're outfitting a sportfishing yacht, a cruising sailboat, or a commercial workboat, this pump stands out for its ability to handle substantial steering loads without faltering. It pairs perfectly with advanced autopilot systems, providing the muscle needed for responsive control.

Key Features and Specifications

• Voltage: Optimized for 12V DC systems, ideal for most modern recreational and commercial vessels.
• Cylinder Compatibility: Tailored for 23-36 cu. in. displacement, covering a wide range of hydraulic steering setups.
• Compact Design: Space-efficient mounting options make it easy to install in tight engine rooms or lazarettes.
• Durable Construction: Built with corrosion-resistant materials to withstand harsh saltwater environments and constant vibration.
• High-Efficiency Motor: Delivers smooth, powerful ram movement with minimal power draw, extending battery life on extended trips.
• Quiet Operation: Minimizes noise below deck, ensuring a comfortable cabin experience.

These features combine to offer superior thrust and holding power, making it a go-to choice for skippers who demand unwavering reliability from their steering gear.

Seamless Compatibility with Autopilot Systems

This pump integrates effortlessly with NAC-3 autopilot computers and AC42 course computers, unlocking full potential in sophisticated setups. It's the perfect match for boats requiring heavy-duty hydraulic assistance, ensuring your autopilot can track waypoints flawlessly across varying sea states.

Compatible with a broad array of hydraulic rams and steering cylinders in this displacement range, it adapts to your existing hardware without major modifications. Always verify system requirements to pair it correctly for optimal performance.

Performance Benefits for Serious Boaters

Experience the difference in autopilot responsiveness: quicker rudder response times reduce wear on steering components and improve fuel efficiency by maintaining optimal trim. In beam seas or following winds, its high-torque output prevents autopilot hunting, keeping your boat on course with minimal corrections.

Skippers report fewer manual overrides during challenging conditions, translating to less fatigue on multi-day voyages. Its robust build also means longer service intervals, saving time and costs in the long run compared to lesser pumps that struggle under load.

Installation and Setup Tips

Professional installation is recommended, but handy boat owners can tackle it with basic tools. Mount the pump securely near the steering cylinder, ensuring rigid hydraulic lines to avoid air pockets that could cause erratic steering. Bleed the system thoroughly post-installation—start with the highest point and work down—to achieve prime performance.

• Check electrical connections for polarity to prevent motor damage.
• Use marine-grade fittings and hoses rated for high pressure.
• Test under load in calm water before heading offshore.

For best results, calibrate your autopilot after hookup to fine-tune gain settings for your boat's specific hull dynamics.

Maintenance for Long-Term Reliability

Keep it running like new with simple routines: Inspect hydraulic fluid levels annually and top off with compatible ATF if low. Listen for unusual motor hums during operation, which might signal seal wear—address promptly to avoid downtime. Rinse external parts with fresh water after saltwater exposure to combat corrosion.

A well-maintained unit can last over a decade, even in demanding charter fleets. Proactive care ensures it performs when you need it most, like during sudden squalls or autopilot-dependent navigation.
