Upgrade Your Boat's Steering with Precision and Power

Imagine effortless control on open water, where every turn feels responsive and your autopilot never skips a beat. The Simrad PUMP-5 MKII stands out as a robust reversible hydraulic pump designed for marine enthusiasts who demand reliability from their steering systems. Operating on 24V DC, this pump delivers a high flow rate of 3.0 liters per minute, making it ideal for handling cylinder displacements between 290-960 cc (17.7-58.5 cubic inches). Whether you're navigating rough seas or cruising calmly, it ensures smooth, precise operation without the lag or hesitation that plagues lesser pumps.

Built for real-world boating challenges, this pump integrates seamlessly with advanced autopilot setups, including SteadySteer technology. That means continuous steering corrections without the common "hunting" issue—your boat stays on course while you focus on the horizon. Boaters upgrading from older hydraulic systems rave about the difference in power and quiet performance, especially on larger outboards or twin-engine setups.

Key Features That Set It Apart

• Reversible Design: Easily switches direction for port or starboard steering, simplifying control in tight maneuvers or autopilot mode.
• High-Flow Efficiency: Pumps at 3.0L/min to quickly actuate larger rams, reducing response time during critical moments.
• 24V DC Power: Matches modern vessel electrical systems for consistent performance without voltage drops.
• Versatile Displacement Range: Handles 17.7-58.5 cu. in. cylinders, perfect for a wide array of boat sizes from mid-range center consoles to sportfishers.
• SteadySteer Ready: Pairs with NAC-3 or AC42 autopilots for jitter-free tracking, enhancing fuel efficiency and safety on long passages.
• ORB Connections: O-Ring Boss fittings ensure leak-proof seals, with included adapters for straightforward hose integration.

Unlike basic pumps that struggle under load, this MKII model uses durable gear technology for longevity, even in saltwater environments. It's engineered to withstand vibrations, corrosion, and constant use—qualities that shine in offshore adventures.

Perfect Fit for Your Vessel's Needs

This pump excels in hydraulic steering conversions or replacements, supporting mechanical, hydraulic, or solenoid feedback setups. For outboard owners, it provides the muscle for hydraulic rams on 20-50 foot boats. Inboard and sterndrive applications benefit from its reversible action, mimicking power steering feel without the bulk of traditional cylinders.

Compatibility extends to Simrad's ecosystem, but savvy installers pair it with third-party autopilots requiring precise hydraulic feedback. The result? A steering system that's as intuitive as your boat's throttle, cutting down on arm fatigue during extended trips.

Simple Integration and Long-Term Reliability

Installation boils down to secure mounting, electrical hookup, and fluid lines—typically a weekend project for DIYers with basic tools. Position it low and central to minimize air pockets, and use quality ATF fluid for optimal flow. Once running, its self-priming nature gets you back on the water fast.

Maintenance is straightforward: Check fittings annually, top off fluid, and inspect for wear. With proper care, expect years of trouble-free service, far outlasting competitors prone to seal failures. Boaters report zero downtime even after thousands of cycles, making it a smart investment for frequent use.
