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 CM806188Z is a zinc bearing carrier anode designed specifically for MerCruiser Bravo I stern drives. This sacrificial anode provides essential corrosion protection for your outdrive by preventing galvanic corrosion that can damage vital aluminum components.

Key Features:

  • Manufactured from mil-spec MIL-A-18001K zinc alloy for reliable corrosion protection
  • Located at the aft end of the bearing carrier surrounding the propeller shaft
  • Outer diameter: 2.75 inches (70mm)
  • Mounting hole spacing center-to-center: 2.91 inches (73.9mm)
  • Bolt hole diameter: 0.2 inches (5mm)
  • Depth: 0.9 inches (23mm)
  • Requires 5/16-inch or 8mm wrench for installation

Martyr anodes are engineered to erode inward, giving the anode a sandblasted appearance that allows for easy visual inspection of remaining protection life. Anodes should be replaced when they are 70% eroded to maintain optimal corrosion protection. Always check propeller clearance after installing new bearing carrier anodes.

So far, so good. Easy to purchase. Good fit and speedy delivery.

Quick and easy. Could have left or right side in description though. Other than that 1 phone call cleared up the left and right confusion and placed my order. Great service. I even used again for my rear Lateral arms I just purchased

Excellent price and availability. Thank you.

Easy order. Like being able to buy through my amazon account.

checkout software gave me some grief first time around but finally worked ok.

Easy!!! Fast.... the items were fine but the packing suffered horribly in transit. The box was tattered and sagging but the contents had not gotten out.....yet. Other than that everything was swell.
