Furuno Rudder Reference f/Outboards On Navpilot 500 & 511 Autopilots

Enhance the precision of your outboard-powered vessel's steering with the Furuno FAPAR4502 Rudder Reference Unit, designed exclusively for NavPilot 500 and 511 autopilot systems. This compact sensor delivers real-time feedback on your rudder's position, allowing the autopilot to make micro-adjustments for smoother, more efficient navigation—even in choppy waters or during long hauls.

Boat operators know the frustration of autopilot drift without accurate rudder data. The FAPAR4502 solves this by mounting directly to your hydraulic steering cylinder, accommodating up to an 8-inch stroke length common in outboard setups. It transmits precise angle measurements to the NavPilot, enabling features like advanced heading hold, auto-tracking, and fish-finder integration for spot-on performance.

Why Add a Rudder Reference to Your NavPilot Setup?

• Superior Course Keeping: Locks in your heading with minimal overshoot, reducing crew fatigue on extended trips.
• Fuel Savings: Optimized steering cuts down on unnecessary throttle bursts, preserving range for offshore adventures.
• Safety Boost: Responsive feedback prevents unintended swings in crosswinds or currents, ideal for trailering or docking.
• Outboard Compatibility: Tailored for hydraulic rams on popular outboard motors, ensuring seamless fit without custom mods.

Unlike basic autopilots relying on compass alone, this unit provides closed-loop control—think of it as giving your NavPilot eyes on the rudder for unmatched accuracy.

Simple Integration and Reliable Operation

Installation is straightforward for DIY-savvy boaters: Secure the sensor to the cylinder with included hardware, route the cable to your NavPilot control unit, and calibrate via the autopilot menu. No drilling or major disassembly required. Once connected, it withstands saltwater exposure and vibrations, backed by Furuno's marine-grade durability.

For best results, pair it with a properly sized hydraulic pump and steering system. Regular checks on cable connections and zero-point calibration keep it performing like new season after season.

Real-World Performance Insights

Anglers targeting deep-water species rave about how the FAPAR4502 holds position during drifts, letting them focus on the rod tip. Cruisers appreciate the steady track on coastal runs, while tournament pros credit it for consistent speeds in slalom courses. It's not just an accessory—it's the missing link for turning your NavPilot into a pro-level steering system.
