Airmar B617V Bronze Housing with Integrated Valve

The Airmar B617V Bronze Housing with Integrated Valve is a thru-hull transducer mounting system engineered for serious anglers and boaters who demand reliable sonar performance in saltwater and freshwater environments. This low-profile bronze housing is designed to accommodate Airmar's most popular intelligent sensors—including the DT800, DST800, UST850, UDST800, and DST810 models—making it an essential component for fishfinders, chartplotters, and navigation systems. Whether you're running offshore structure, scanning shallow flats, or mapping your favorite lake, this housing provides the secure, corrosion-resistant platform your sonar transducer needs to perform consistently season after season.

Cast from marine-grade bronze, the B617V housing resists galvanic corrosion and saltwater degradation—critical advantages when mounting through a hull where exposure to spray, immersion, and electrolytic action can quickly compromise lesser materials. The integrated valve system allows for sealed installation without compromising the transducer's acoustic path, and the 2-12 thread specification ensures compatibility with standard thru-hull applications across multiple hull types and materials. At just 1 pound, the low-profile design minimizes drag while maintaining structural rigidity, and the bronze construction provides both strength and thermal stability for transducers operating across varying water temperatures.

Installation of the Airmar B617V is straightforward for anyone with basic mechanical experience—the thru-hull fitting drops into prepared mounting holes and secures with the integrated valve mechanism, creating a watertight seal that protects your cabin and keeps your sonar running clean. This housing is ideal for recreational anglers upgrading older systems, charter and guide operations running multiple vessels, and any boater serious about maintaining accurate real-time bottom mapping and fish detection. Compatibility with Airmar's Smart Sensors means you gain access to advanced features like temperature compensation and network-ready diagnostics, making this a future-proof investment for electronics-equipped boats.
