Furuno AIR-033-391 B260 High Speed Fairing Block

The Furuno AIR-033-391 B260 High Speed Fairing Block is a precision hydrodynamic fairing designed for transducers utilizing the Airmar B-260 housing. This component minimizes water turbulence and signal interference around your transducer, ensuring clean, accurate sonar readings even at high speeds. The fairing block is essential for offshore anglers and commercial operators who depend on consistent target detection and bottom tracking in demanding conditions.

Built to Furuno's marine-grade standards, the AIR-033-391 measures 6 × 6 × 24 inches and weighs 9.1 lbs, engineered to integrate seamlessly with B-260 compatible transducers. The fairing block's streamlined profile reduces cavitation—the formation of air bubbles around the transducer at speed—which would otherwise degrade sonar performance and create false echoes. This is particularly critical for fish-finding applications where precise water column imaging determines success on the water.

Serious anglers running high-speed offshore vessels, professional charter operations, and commercial fishing platforms benefit most from this fairing block. Weekend fishermen operating at moderate speeds may see less pronounced improvement, but the investment becomes worthwhile for any boat that regularly cruises above 20 knots while relying on sonar for navigation and fish location. Proper fairing ensures your Furuno electronics investment delivers the clarity and reliability they were designed to provide.

This component pairs directly with Furuno transducers and systems that employ the Airmar B-260 mounting architecture. Before ordering, confirm your existing transducer housing matches the B-260 specification to ensure proper fit and optimal performance. SKU CW11814.
