Product Details

The Martyr Anodes CMR04M is a precision-engineered magnesium sacrificial anode designed specifically for rudders and trim tabs on marine vessels. This anode provides superior cathodic protection against galvanic corrosion in freshwater and brackish water environments.

Key Features:

  • High-purity magnesium alloy construction for maximum corrosion protection
  • Includes stainless steel Allen head screw for secure installation
  • Pre-drilled mounting hole for easy attachment to rudders and trim tabs
  • Designed to corrode preferentially, protecting valuable underwater metal components
  • Compact profile minimizes drag while providing effective protection

Martyr Anodes are manufactured to strict quality standards and are among the most trusted sacrificial anodes in the marine industry. Regular inspection and replacement of sacrificial anodes is essential for protecting your vessel's underwater metals from costly corrosion damage.
