Raymarine B45 Bronze Thru-Hull w/Fairing Block f/ST60

The Raymarine B45 Bronze Thru-Hull with Fairing Block for ST60 is a marine-grade transducer housing designed for anglers and boaters who demand reliable depth and water temperature data in challenging saltwater and freshwater environments. This bronze thru-hull assembly serves as the foundation for accurate sonar performance, offering the durability and corrosion resistance that serious anglers require when fishing in coastal waters or extended offshore expeditions. Built to integrate seamlessly with Raymarine's proven instrument systems, this thru-hull transducer is essential for anyone upgrading or maintaining a fishing vessel's electronics package.

The B45 Bronze thru-hull features a robust bronze construction that resists corrosion and marine fouling far better than standard plastic housings, ensuring consistent sonar readings season after season. The included fairing block minimizes turbulence and improves signal clarity by streamlining water flow around the transducer, a critical advantage when running at high speeds or when operating in rough seas. Installation requires a 7/8-inch hole and the 45-foot cable provides flexible mounting options whether your helm station sits forward, aft, or amidships, making this unit compatible with wood and fiberglass hulls across a wide range of vessel sizes.

This thru-hull assembly works with Raymarine ST60+, ST70, and ST290 instruments, giving you access to real-time water temperature, depth readings, and speed data critical for fish finding and navigation. Boaters upgrading legacy systems or installing fresh electronics will appreciate the direct compatibility with Raymarine's trusted display units, eliminating guesswork during installation. The bronze construction and fairing block design make this thru-hull particularly suited to saltwater charter operations, serious tournament anglers, and cruising boaters who log thousands of hours on the water and refuse to compromise on instrument reliability.
