Martyr Anodes

<h3>About Martyr Anodes</h3><p>When it comes to defending a vessel against galvanic corrosion, few names carry the authority of <strong>Martyr Anodes</strong>. A flagship brand within the <strong>CMP Group</strong>, Martyr has its roots in foundry operations that date back to the early 1900s in Vancouver, BC, growing from a local manufacturer into a globally recognized leader in marine cathodic protection. Today, the brand supplies boaters, commercial operators, and marine professionals worldwide with sacrificial anodes engineered to guard hulls, propellers, rudders, shafts, engines, and other submerged components from the relentless effects of corrosion.</p><h3>Three Alloys, Every Water Type</h3><p>What sets Martyr apart from competing anode manufacturers is its position as the only brand to offer all three protective alloys — zinc, aluminum, and magnesium — under a single product line. This matters because the correct alloy depends entirely on the water environment a vessel operates in. Zinc anodes are the classic choice for aggressive saltwater conditions, while aluminum anodes are preferred for saltwater and brackish environments, offering superior corrosion resistance with a reduced environmental footprint. Magnesium anodes are the go-to solution for freshwater use, delivering effective sacrificial protection without degrading too quickly. Whatever the operating environment, Martyr has an engineered solution to match.</p><h3>Military-Grade Manufacturing Standards</h3><p>Martyr does not cut corners on metallurgy. Every anode is pressure die-cast and manufactured to meet or exceed <strong>U.S. Military alloy specifications</strong>, using only high-purity metals. Each alloy batch is lab-tested with full certification and traceability available upon request. This rigorous quality management — operating under an ISO 9001 framework — ensures that each anode delivers consistent, long-lasting galvanic performance across a wide range of marine environments, from recreational pleasure craft to commercial vessels and naval applications.</p><h3>Anode Kits for Simplified Protection</h3><p>For boaters who want a complete, hassle-free maintenance solution, Martyr&rsquo;s <a href="/7452-martyr-anodes-anode-kits-200102">Anode Kits</a> offer pre-packaged sets engineered for specific engine models and boat types. Compatible with major marine engine brands including Yamaha, Mercury, Volvo, and MerCruiser, these kits take the guesswork out of corrosion protection and ensure every critical system receives optimal coverage in a single purchase.</p><h3>Sustainability at the Core</h3><p>Martyr and the CMP Group have made environmental stewardship a cornerstone of their mission. Traditional zinc anodes can contain cadmium, a metal that poses risks to aquatic ecosystems. Martyr actively advocates for the adoption of aluminum and magnesium alternatives that deliver equal or superior protection while minimizing harm to marine environments — embodying the brand&rsquo;s philosophy of &ldquo;Protect your boat, protect our waters.&rdquo; With over 1,000 anode types available and a catalog that fits virtually every major marine engine and boat model, Martyr remains one of the most comprehensive and trusted sources for marine corrosion protection in the world.</p>

Product Details

The Martyr Anodes CMM24 is a bolt-on zinc hull anode designed to provide reliable sacrificial corrosion protection for marine vessels in saltwater environments. This anode protects underwater metal components such as shafts, rudders, struts, and trim tabs by corroding preferentially, preventing galvanic corrosion damage to more expensive boat hardware.

Key Specifications:

  • Dimensions: 0.7" thick x 1.92" wide x 4.36" long
  • Material: MIL-SPEC high-grade zinc alloy
  • Configuration: Bolt-on hull mount design with pre-drilled mounting holes
  • Application: Ideal for saltwater use on boats, yachts, and marine vessels
  • Protection: Guards against galvanic corrosion on underwater metal components

Martyr anodes are manufactured to strict military specifications, ensuring consistent performance and maximum protection. The CMM24 features precision-drilled mounting holes for secure installation directly to the hull. Regular inspection and replacement of sacrificial anodes is essential for maintaining proper corrosion protection and extending the life of your vessel's underwater metals.

Autoplcity got my order shipped quick! I wanted to make sure that it was the right order and they helped me out through chat no problem. They're also centrally located so I suppose shipments to anywhere in the US wouldn't take long at all. They also had a part that I couldn't find anywhere in Salt lake and only few other places on the Internet. None at this good a price. I'm sticking with these guys.
