Furuno AIR-033-719-01 Replacement Fairing Block for 165T-B54 and 165T-SS54 Transducers

The Furuno AIR-033-719-01 is a genuine OEM replacement fairing block designed specifically for use with the Furuno 165T-B54 and 165T-SS54 through-hull transducers — the multibeam transducers used with the Furuno DFF3D Multibeam Sonar system.

A fairing block is a hydrodynamically shaped mounting wedge that is installed on the hull of the vessel to ensure the transducer face sits level and parallel to the water surface, even on hulls with deadrise or curvature. Proper fairing block installation is essential for optimal sonar performance, eliminating signal distortion caused by an off-angle transducer face.

Key Features:

• Genuine Furuno OEM replacement part (MPN: AIR-033-719-01)
• Designed for the Furuno 165T-B54 and 165T-SS54 through-hull transducers
• Compatible with the Furuno DFF3D Multibeam Sonar system
• Includes uncut fairing block and anti-rotational bolt kit
• Allows correct transducer alignment on angled or curved hull sections
• Required for standard through-hull installations where the transducer is not pocket mounted or flush mounted in a level keel

This fairing block is ideal for replacement or new installations of the 165T-B54 or 165T-SS54 transducer. It comes uncut, allowing the installer to trim it to match the specific deadrise angle of the hull for a precise, watertight fit.
