Furuno AIR-033-391 B260 High Speed Fairing Block — Product description

Enhance your marine sonar setup with the Furuno AIR-033-391 fairing block, expertly designed for the Airmar B260 transducer. This high-speed fairing block streamlines water flow around your thru-hull transducer, minimizing drag and turbulence to maintain crystal-clear sonar readings even when pushing your vessel to higher speeds. Boaters who demand precision—whether chasing trophy fish offshore or navigating challenging waters—rely on this accessory to unlock the full potential of their B260 transducer without compromising on performance.

Why This Fairing Block Delivers Superior Results

Crafted from durable, marine-grade materials, the AIR-033-391 withstands the relentless pounding of saltwater environments and high-velocity conditions. Unlike basic mounts, this fairing aligns the transducer housing perfectly with your hull's contour, reducing cavitation that often plagues fast-moving boats. The result? Consistent, high-resolution sonar data from surface to depths, helping you spot structure, bait balls, and game fish with unmatched clarity.

  • Optimized Hydrodynamics: Cuts through water efficiently, supporting speeds beyond 30 knots without signal degradation.
  • Proven Durability: Built to endure harsh marine conditions, from pounding waves to corrosive saltwater exposure.
  • Seamless Integration: Precision-molded for the B260 housing, ensuring a flush, low-profile fit.
  • User-Friendly Design: Simplifies installation for DIY boaters or pros, saving time and hassle during transducer upgrades.
  • Backed Assurance: Comes with reliable manufacturer support for peace of mind on every outing.

Real-World Performance for Serious Boaters

Imagine planing across open water at full throttle, your Furuno fishfinder displaying sharp, uninterrupted bottom contours and fish arches. The AIR-033-391 makes this reality by eliminating the common pitfalls of transducer misalignment—erratic readings, dead zones, and lost targets. It's a game-changer for offshore anglers, sportfishing enthusiasts, and commercial operators who can't afford downtime or fuzzy data. Paired with CHIRP-capable B260 models, it amplifies wideband frequency sweeps for superior target separation in varied water columns.

Installation Insights for Peak Setup

Getting the most from your fairing block starts with proper hull preparation. Clean the mounting area thoroughly, then bed the block with marine sealant for a watertight seal. Align it dead-center with your transducer's fore-aft axis, using the hull's deadrise angle as a guide—typically 12-20 degrees for most planing hulls. Secure with stainless fasteners, and test at idle before ramping up speed. Pro tip: Angle the transducer slightly downward (2-5 degrees) to account for hull lift at speed, ensuring the beam stays locked on the bottom.

This straightforward process means you can be back on the water in hours, not days, with sonar performance elevated to professional levels.
