Simrad LFI3000 Mk2 Linear Feedback Interface Box Only

Enhance your boating experience with the Simrad LFI3000 Mk2, a compact yet powerful interface box designed specifically for seamless integration in outboard setups. This unit bridges the gap between your LF3000 linear feedback transducer and the autopilot steering computer, transforming analog signals into precise digital feedback for smoother, more reliable steering control.

Why Every Outboard Enthusiast Needs the LFI3000 Mk2

Outboard motors demand specialized feedback solutions due to their unique hydraulic steering dynamics. Without the right interface, your autopilot might struggle with inconsistent signals, leading to erratic course holding or unnecessary rudder adjustments. The LFI3000 Mk2 solves this by delivering clean, standardized digital output that your Simrad autopilot can interpret flawlessly. Imagine long hauls across open water where your system maintains a rock-steady heading, freeing you to focus on navigation, fishing, or simply enjoying the ride.

Key Features That Set It Apart

• Analog-to-Digital Conversion: Effortlessly converts LF3000's analog output to NAC-2/NAC-3 compatible digital signals, ensuring compatibility with modern Simrad autopilots.
• Rugged Marine Build: IPX7 waterproof rating and corrosion-resistant housing withstand harsh saltwater environments, vibrations, and impacts common on outboards.
• Plug-and-Play Simplicity: Minimal wiring required—connects directly between the LF3000 transducer and your autopilot computer for quick setup.
• Precision Tuning: Adjustable gain and zero-point settings allow fine-tuning to match your boat's steering geometry, optimizing performance for various hull sizes and outboard configurations.
• Diagnostic LEDs: Built-in indicators for power, signal presence, and fault detection make troubleshooting a breeze without specialized tools.

Installation Made Easy: Step-by-Step Insights

Mounting the LFI3000 Mk2 is straightforward, even for DIY boaters. Secure it near your steering ram or helm station using included brackets. Connect the LF3000's output cable to the input port, then run a dedicated feedback line to your autopilot's NAC processor. Power it from your 12V DC system—draw is minimal, under 50mA. Calibrate via your autopilot's setup menu by following the on-screen prompts for rudder limits and feedback gain. Pro tip: Test in calm waters first, adjusting sensitivity to eliminate any oscillation before hitting rough seas.

For outboards with hydraulic steering rams, position the LF3000 transducer parallel to the ram for maximum stroke feedback. This setup shines on center-console fishing boats, offshore cruisers, and sportfishers where autopilot reliability is non-negotiable.

Real-World Performance and Longevity

Boaters report up to 30% improved course-holding accuracy in choppy conditions compared to non-interfaced systems. It's not just about steering—consistent feedback reduces wear on pumps and rams, extending your hydraulic system's life. Regular checks for loose connections and clean terminals keep it performing like new season after season.

Common Challenges and Smart Solutions

If you notice intermittent signal loss, inspect cable routing away from high-current lines to avoid interference. Overly aggressive gain can cause hunting; dial it back incrementally. In cold climates, ensure no ice buildup affects the LF3000 transducer, as the interface handles signal conditioning reliably down to freezing temps.
