B & S Anodes BSM214SL Shaft Zinc Anode 2-1/4 Inch Streamline Collar

The B & S Anodes BSM214SL is a high-quality streamline shaft zinc anode designed for 2-1/4 inch propeller shafts on inboard marine engines. This sacrificial anode provides essential cathodic protection for underwater metal components including propellers, shafts, struts, rudders, and bearings in saltwater environments.

Key Features:

• 2-1/4 inch shaft diameter streamline collar design
• Cast from special alloy zinc meeting Military Specification MIL-A-18001K
• Stainless steel allen head socket cap screws for secure mounting
• Copper contact points for permanent electrical ground connection
• Pressed-in stainless steel nuts that won't fall out during installation
• Plastic retaining washers keep screws in place during setup

This zinc anode protects against galvanic corrosion by serving as the sacrificial element that corrodes instead of more expensive metal components. B & S anodes use hand-poured zinc with higher porosity than die-cast alternatives, providing greater surface area exposure for enhanced corrosion protection. Cross-references Camp X-10, Martyr CMX10, and other compatible part numbers. Recommended for saltwater use only.
