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 CMY200350FLKITM is a complete magnesium sacrificial anode kit designed to protect Yamaha 200–350 HP outboard motors from galvanic corrosion in freshwater environments. This kit features a flat tab trim anode configuration, making it the correct choice for counter-rotating or specific Yamaha outboard setups that require a flat-profile tab anode rather than the standard angled trim tab.

Martyr's Martyr III magnesium alloy anodes are engineered exclusively for freshwater use. Magnesium is the most electrochemically active of the three anode materials, providing aggressive cathodic protection necessary in low-conductivity fresh water where zinc anodes can passivate and fail to protect. Do not use magnesium anodes in saltwater or brackish water, as they will corrode too rapidly.

Key Features:

  • Magnesium alloy construction — optimized for freshwater use only
  • 100% cadmium-free formulation — environmentally responsible
  • Manufactured to US Military alloy specifications for consistent, verified performance
  • Flat tab trim anode design for compatible Yamaha 200–350 HP outboard configurations
  • Chemically tested for alloy consistency and electrochemical efficiency
  • Includes all anodes and fastening hardware needed for a complete service
  • Drop-in replacement for OEM Yamaha sacrificial anodes

Replacing your outboard's sacrificial anodes at regular service intervals is one of the most cost-effective ways to prevent galvanic corrosion damage to expensive lower unit and engine components. The CMY200350FLKITM bundles all necessary anodes and hardware so the job can be completed in one service session.

Fast shipping, easy website. What more could you need?!?

Surprised how through the shopping experience was and my tire was delivered extremely fast will definitely be back for future purchases:)
