Furuno AIR-033-476 High-Speed Fairing Block

Enhance Your Transducer Performance with Precision Engineering

Navigating at high speeds demands equipment that cuts through water with minimal resistance. The high-speed fairing block pairs seamlessly with transducers in the Airmar B-744V housing, transforming how your sonar setup handles dynamic marine environments. Designed for vessels pushing boundaries on open water, this fairing block streamlines flow around the transducer, slashing turbulence and drag that can muddy readings or compromise hull efficiency.

Whether you're chasing big game offshore or racing across bays, this component ensures crystal-clear data from your Furuno sounder system. It mounts flush to your hull, creating a hydrodynamic profile that maintains accuracy even as speeds climb above 30 knots—ideal for serious anglers, surveyors, and performance boaters who refuse to compromise on signal quality.

Key Features That Set It Apart

• Optimized Hydrodynamics: Precision-molded shape reduces water disturbance by up to 50%, delivering stable transducer performance at elevated velocities.
• Perfect Fit for B-744V Housing: Engineered exclusively for Airmar B-744V transducers, ensuring a snug, vibration-free installation that preserves warranty integrity.
• Durable Marine-Grade Materials: Built to withstand constant saltwater exposure, UV rays, and impacts without cracking or delaminating over seasons of heavy use.
• Low-Profile Design: Minimizes added drag on your hull, helping maintain top-end speed and fuel economy without bulky protrusions.
• Easy Retrofit Compatibility: Works with existing Furuno installations, making upgrades straightforward for enhanced high-speed reliability.

How It Boosts Your On-Water Experience

At cruising speeds, unprotected transducers suffer from bubbles and flow separation, leading to signal noise and lost bottom detail. This fairing block acts as a hydrodynamic shield, channeling water smoothly over the face for pinpoint target separation and depth accuracy. Boaters report sharper fish arches, cleaner wrecks, and reliable structure scans—crucial when seconds count in tournaments or tight navigation.

Real-World Applications

• Offshore fishing: Steady returns at 35+ knots for deep-water pelagics.
• Survey vessels: Consistent data logs during high-speed transects.
• Performance hulls: Preserves planing efficiency with zero compromises.

Pro tip: Pair it with broadband transducers for the ultimate combo in clarity and range, turning your setup into a high-speed sonar powerhouse.

Installation Insights for Flawless Results

Getting it right starts with hull prep. Clean the mounting area thoroughly, then bed the fairing with marine sealant for a watertight bond. Align precisely with the transducer keel line to avoid any offset that could induce yaw. Most installs take under an hour with basic tools—no hull modifications required for standard thru-hull setups.

1. Mark and drill pilot holes per template.
2. Apply sealant and secure with stainless fasteners.
3. Torque to spec and fair with gelcoat for seamless finish.
4. Test at idle, then ramp up speeds to verify smooth operation.

Common pitfalls? Skipping the template or uneven bedding—both lead to leaks or misalignment. Follow these steps, and you'll enjoy drag-free performance from day one.

Why High-Speed Fairings Matter More Than Ever

In today's faster vessels, ignoring fairing tech means settling for subpar sonar. This block addresses the physics head-on: by angling water flow at optimal attack angles, it prevents cavitation bubbles that scramble echoes. Result? Deeper penetration, finer resolution, and confidence in every reading, no matter the hull speed.
