Martyr Anodes CMX05AS Streamlined Shaft Zinc Anode with Stainless Steel Slotted Head

The Martyr Anodes CMX05AS is a streamlined shaft zinc anode designed to provide superior galvanic corrosion protection for propeller shafts on boats operating in saltwater and brackish environments. This precision-engineered anode features a low-profile, hydrodynamic design that minimizes drag while maximizing protection for your vessel's underwater metal components.

Key Features:

• Premium zinc alloy construction for optimal galvanic protection in saltwater
• Streamlined profile reduces water resistance and maintains boat performance
• Stainless steel slotted head hardware included for secure, corrosion-resistant installation
• Precision-machined design ensures proper fit on propeller shafts
• Meets or exceeds MIL-SPEC standards for marine zinc anodes
• Easy installation and replacement as part of routine maintenance

Martyr is a trusted name in marine cathodic protection, manufacturing anodes to strict military specifications using high-purity metals. This shaft anode sacrifices itself to protect more expensive components like propellers, shafts, rudders, and through-hull fittings from destructive galvanic corrosion. Regular inspection and replacement of sacrificial anodes is essential for maintaining your vessel's integrity and preventing costly repairs.
