Furuno B275LHW-12P Bronze Thru Hull with 12-Pin

The Furuno B275LHW-12P Bronze Thru Hull with 12-Pin connector is the backbone of reliable sonar performance on modern fishing vessels and cruising boats. Built for anglers and captains who demand consistent bottom contact and accurate fish-finding capability in freshwater and saltwater applications, this thru-hull transducer integrates seamlessly with Furuno's ecosystem of marine electronics. Whether you're targeting structure in deep lakes or running offshore, the B275LHW-12P delivers the imaging clarity and durability required for serious boating.

Constructed from bronze, this transducer resists corrosion and galvanic attack—critical for saltwater vessels and boats that spend weeks at a time away from fresh-water rinse stations. The 12-pin connector architecture ensures robust electrical continuity and eliminates the intermittent signal loss that plagued older single-pin designs. The thru-hull mounting system positions the transducer flush with the hull, minimizing turbulence and noise interference while preserving hydrodynamic efficiency. At 24.3 pounds, it's engineered for secure installation in deadrise hulls and modern composite bottoms without requiring reinforcement on properly prepared mounting surfaces.

This transducer suits both retrofit and new-build installations on vessels equipped with Furuno fish finders, chartplotters, and integrated multifunction displays using the 12-pin standard. Professional installers and experienced DIYers appreciate the straightforward through-hull design, which avoids the complexity of in-hull mounting. Compatibility with Furuno sounder systems ensures you're investing in a component that will communicate reliably with current and legacy equipment, making the B275LHW-12P a smart upgrade for cruisers and commercial operations seeking confidence in their navigation and fishing electronics.
