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 35SS640 is a precision-engineered streamlined shaft anode designed to provide superior corrosion protection for propeller shafts in marine environments. This two-piece clamp-on anode features a hydrodynamic design that minimizes drag while sacrificing itself to protect your valuable shaft, strut, and propeller components from galvanic corrosion.

Key Features:

  • Two-piece split design allows for easy underwater installation without shaft removal
  • Streamlined aerodynamic profile reduces drag and turbulence for optimal performance
  • 100% circular radius ensures complete shaft contact for maximum protection
  • Interlocking halves create secure fit and prevent separation
  • Stainless steel bolt retaining washers prevent the anode from falling off during operation
  • Extra alloy material around fasteners for extended service life
  • Manufactured to meet or exceed U.S. Military Specification MIL-DTL-24779C(SH)
  • Made from high-purity specialized alloy with lab-tested quality certification

Martyr Anodes are recognized worldwide as premium marine anodes, built to strict mil-spec standards to ensure dependable protection in saltwater and brackish water environments. Each alloy batch is rigorously tested to meet stringent quality standards, with full certification and traceability available upon request. The streamlined design of this shaft anode makes it ideal for sailboats and powerboats where performance and corrosion protection are equally important.

Great service

Good prices and product availability.

fast and easy

The only thing that would have been better is if the tracking number brought up a map or something more than the order that was placed. Can't wait to install my parts. Thanks.

So far good!!
