B & S Anodes BSM212SL Shaft Zinc Anode 2-1/2 Inch

The B & S Anodes BSM212SL is a 2-1/2 inch shaft zinc anode designed to protect propeller shafts and other underwater metal components from galvanic corrosion in saltwater and brackish water environments. This sacrificial anode attaches directly to the propeller shaft, where it corrodes preferentially to protect more expensive bronze, stainless steel, and aluminum components from electrolysis damage.

Key Features:

• 2-1/2 inch diameter shaft zinc anode
• Protects propeller shafts and underwater metals from galvanic corrosion
• Designed for saltwater and brackish water marine applications
• Sacrificial zinc material corrodes to protect valuable components
• Easy installation on propeller shafts
• Manufactured by B & S Anodes for reliable corrosion protection

Regular inspection and replacement of shaft zincs is essential for maintaining proper corrosion protection on marine vessels. Replace when the anode has corroded to approximately 50% of its original size to ensure continued protection of your boat's underwater metal components.
