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 CM806189Z is a high-quality sacrificial zinc anode designed specifically for Mercury Mercruiser stern drives and outboards. This trim tab anode replaces Mercury part number 806189 and provides essential corrosion protection for your drive unit in saltwater and brackish water environments.

Key Features:

  • Direct replacement for Mercury OEM part number 806189
  • Manufactured from high-purity zinc alloy for maximum protection
  • Mounts directly to the trim tab assembly
  • Protects expensive drive components from galvanic corrosion
  • Easy installation with proper hardware included

Sacrificial anodes work by corroding preferentially to protect more valuable metal components on your drive system. Regular inspection and replacement of anodes is essential preventive maintenance for any boat operating in saltwater. Always verify propeller clearance after installation to ensure proper fitment and avoid damage to your propeller or drive unit.

Looksgood on the website...

sounds too inexpensive, but hey you only live once...

autoplicity has been great, fast order processing and great prices!

Excellent prices on all the items I have searched and very fast and reasonable shipping.

Quick, secure checkout.

My first order did not include all parts. I'm ordering a different part number now. The seller is giving me a discount due to this inconvenience. We will see how it goes.

So far so good. Only time will tell. Received what I ordered today. Too bad not here for the weekend.

Fast order. Good prices. Delivery confirmation. Great company. They had a part I wanted to add for my mustang for about $80.00 less than the competition it was a no brainer. Shipping out from factory took about 2 days but overall everything was very prompt.
