Martyr Anodes CMMZC406M Magnesium Hull Anode 8-5/8" x 4-1/4" x 1"

The Martyr CMMZC406M is a magnesium hull anode designed to provide superior galvanic corrosion protection for boats operating in freshwater and brackish water environments. This sacrificial anode protects underwater metal components including hulls, outdrives, trim tabs, and propellers by corroding preferentially, extending the life of more expensive marine hardware.

Key Features:

• Magnesium alloy construction optimized for freshwater and brackish water use
• Rectangular hull mount design: 8-5/8" L x 4-1/4" W x 1" H
• Pre-drilled mounting holes for secure installation
• Meets or exceeds military specification MIL-A-21412
• Higher driving voltage than aluminum or zinc anodes for maximum protection in low-conductivity water

Martyr Anodes are manufactured to strict quality standards and provide reliable, long-lasting protection. Regular inspection and replacement of sacrificial anodes is essential for maintaining optimal corrosion protection and preventing costly damage to your vessel's underwater components.
