Navico Pump-2 MK2 Reversible Hydraulic Autopilot Pump - 12V

Enhance Your Vessel's Steering Precision with the Pump-2 MK2

Imagine gliding through choppy waters with confidence, knowing your autopilot delivers smooth, responsive control without constant manual adjustments. The Pump-2 MK2 reversible hydraulic autopilot pump steps in as a game-changer for boaters seeking reliable performance on vessels with hydraulic steering systems. Designed for moderate-duty applications, this 12V pump handles cylinder displacements from 80 to 250 cc (4.9 to 15.2 cubic inches), making it ideal for a range of mid-sized crafts like sportfishing boats, cruisers, and offshore yachts.

What sets it apart? Its reversible gear design allows seamless port-to-starboard transitions, ensuring your autopilot reacts instantly to course corrections. Paired with SteadySteer technology, it brings advanced outboard control to life, minimizing wear on your engine while maximizing efficiency during long hauls or tournament runs.

Robust Features Built for Marine Demands

• Reversible Hydraulic Gear Pump: Delivers a steady 0.8 liters (49 cubic inches) per minute flow rate, balancing power and responsiveness for smooth operation in varied sea conditions.
• Versatile Connectivity: Equipped with O-Ring Boss (ORB) ports and includes three ORB-5 to 9/16 UNF adapters, simplifying integration with existing hydraulic lines and reducing leak risks.
• 12V DC Power: Draws efficiently from standard marine batteries, with low amp draw to preserve power for other onboard systems during extended trips.
• SteadySteer Ready: Unlocks enhanced autopilot features when connected to compatible NAC-2 or AC-12 drives, enabling precise trolling patterns and autopilot holds in rough seas.

Constructed with corrosion-resistant materials, this pump thrives in saltwater environments, shrugging off moisture, salt spray, and UV exposure that plague lesser components.

Seamless Integration and Compatibility

Fitting this pump into your setup is straightforward for those familiar with hydraulic systems. It pairs effortlessly with Simrad and Lowrance autopilot controllers, enhancing systems already equipped for hydraulic rams. Boaters upgrading from older pumps appreciate how the MK2's compact footprint and standard fittings minimize downtime—often a plug-and-play swap with minimal bleeding required.

Pro tip: Verify your cylinder size falls within the 80-250 cc range to ensure optimal performance. It's a perfect match for setups demanding quick response without overwhelming smaller rams, preventing over-pressurization issues common in oversized pumps.

Real-World Performance and Longevity

Users rave about the Pump-2 MK2's reliability during heavy use—think all-day fishing charters or coastal passages. Its moderate flow prevents hydraulic fluid overheating, extending service life compared to high-flow alternatives that strain batteries and generate excess heat. In independent tests and boater forums, it consistently scores high for quiet operation and precise holding power, even against beam seas or following winds.

Beyond specs, it contributes to safer voyages by reducing skipper fatigue. Autopilot takes over repetitive tasks, letting you focus on navigation, fishing, or simply enjoying the water.

Essential Maintenance for Peak Performance

Keep your investment humming with simple routines: Inspect fittings annually for wear, flush the system with clean hydraulic fluid per manufacturer intervals, and monitor for air bubbles post-install. Store spares of the included adapters aboard—they're lifesavers for field repairs. With proper care, expect years of trouble-free service, outlasting pumps exposed to neglect.
