Furuno AIR-033-351 Standard Fairing Block

Enhance the performance of your marine transducer setup with the reliable Furuno AIR-033-351 standard fairing block, meticulously designed for seamless integration with Airmar B-45 housings. This essential accessory plays a crucial role in optimizing sonar and depth sounder accuracy by streamlining water flow around the transducer, minimizing turbulence and air bubbles that can distort readings.

Why Fairing Blocks Matter for Your Boat's Electronics

In the world of boating and fishing, precise underwater data is everything. Without a proper fairing, transducers mounted through the hull can suffer from erratic signals caused by boat-generated wakes or hull irregularities. The AIR-033-351 addresses this head-on, creating a hydrodynamic shape that guides water smoothly over the sensor face. Anglers chasing structure, navigators plotting safe passages, and recreational boaters alike benefit from cleaner, more consistent echo returns, leading to sharper fish arches, better bottom tracking, and reliable depth measurements even at higher speeds.

Crafted from durable marine-grade materials, this fairing withstands harsh saltwater environments, UV exposure, and repeated impacts without compromising integrity. Its standard profile fits most hull shapes, from sleek racing hulls to rugged workboats, ensuring broad applicability without custom fabrication.

Seamless Compatibility with Airmar B-45 Housings

Specifically tailored for transducers in the popular Airmar B-45 series—known for their bronze construction and high-frequency performance—this fairing block snaps into place effortlessly. Whether you're running a Furuno DFF series sounder module, TZTouch multifunction display, or other compatible units, the AIR-033-351 ensures your setup operates at peak efficiency. It supports a range of frequencies, making it ideal for everything from shallow-water trolling to deep-water offshore adventures.

• Universal Fit: Precision-molded for B-45 transducers, no modifications needed.
• Speed Optimized: Reduces cavitation up to planing speeds, maintaining signal quality.
• Easy Alignment: Built-in guides for straight, flush mounting to avoid dead zones.

Installation Insights for Optimal Results

Mounting a fairing block like the AIR-033-351 is straightforward for DIY enthusiasts or pros. Position it aft of the transducer at a slight downward angle to match your hull's deadrise—typically 12 to 20 degrees for many vessels. Secure with marine epoxy or bolts for a rock-solid bond that flexes with the hull under wave action. Pro tip: Test-fit dry before committing adhesive, and always bed everything in sealant to prevent leaks. Once installed, calibrate your sonar unit to account for the improved flow, and you'll notice immediate gains in target separation and bottom hardness discrimination.

Beyond installation, this fairing promotes longevity by shielding the transducer from debris and marine growth buildup. Regular hull cleaning keeps it performing like new, extending the life of your entire electronics suite.

Real-World Performance Boost

Boat owners report up to 30% better high-speed accuracy with faired transducers, translating to fewer false readings during turns or in choppy conditions. For competitive anglers, that means spotting schools faster; for cruisers, it means confident anchoring in unfamiliar bays. Pair it with Furuno's advanced beamforming tech, and you unlock the full potential of narrow-beam transducers for pinpoint precision.
