B & S Anodes BSMB12 Oval Zinc Hull Anode Plate 9" x 4" with 2 Holes

The B & S Anodes BSMB12 is a premium oval zinc hull anode designed to provide reliable cathodic protection for your boat's underwater metal components. This 9-inch by 4-inch zinc plate helps prevent galvanic corrosion on hulls, rudders, shafts, and other submerged metal surfaces in saltwater and brackish water environments.

Key Features:

• Oval zinc plate design measuring 9 inches x 4 inches for broad hull protection
• Two pre-drilled mounting holes for secure installation
• High-purity zinc alloy construction for effective galvanic protection
• Sacrificial anode technology protects more noble metals from corrosion
• Ideal for saltwater and brackish water marine applications
• Direct bolt-on installation to hull or other underwater surfaces

Zinc anodes work by sacrificing themselves to protect more valuable metal components on your vessel. As the most active metal in the galvanic series, zinc corrodes preferentially, preventing corrosion damage to bronze, stainless steel, and aluminum parts. Regular inspection and replacement of zinc anodes is essential for maintaining proper corrosion protection and extending the life of your boat's underwater hardware.
