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 CMALPHAKITM is a complete sacrificial anode kit engineered specifically for Mercury Alpha I Generation II sterndrive units manufactured from 1991 to present. This comprehensive kit provides complete corrosion protection for all critical metal components of your outdrive, helping to prevent costly galvanic corrosion damage in saltwater and freshwater environments.

Complete Protection Kit Includes:

  • CM762145 Trim Tab Anode - Protects the trim tab assembly
  • CM806105 Bearing Carrier Anode - Guards the bearing carrier housing
  • CM821629C Driveshaft Housing Anode - Shields the driveshaft housing
  • CM821631 Gimbal Housing Anode - Protects the gimbal housing assembly
  • (2) CM806189 Trim Ram Anodes - Safeguards both trim ram cylinders

Martyr anodes are manufactured from high-quality aluminum alloy that meets or exceeds military specifications MIL-DTL-24779(SH) and MIL-A-24779(SH). These anodes are designed to sacrifice themselves through electrolysis, protecting more expensive drive components from corrosion. Regular inspection and replacement of sacrificial anodes is essential preventative maintenance that extends the life of your sterndrive and reduces long-term repair costs.

Fitment: Mercury Alpha I Generation II outdrives (1991-Present)

I was only shipped 1 of the 4 bolts needed to assemble the extension on the unit. Had to scrounge the shop to find more bolts. Assembling the unit in that small space was quite the chore. Although a few negatives, I do have to say I am super impressed with the unit!! Very heavy duty and I now feel very safe in leaving valuables in my truck as long as they are locked up in this!! Very well made!!

Quick shipping. Good communication

great price, free shipping and fast delivery time.

Great price and easy site to use

Autoplicity had the best price on these tires on date of purchase. I had selected this brand quite a while back and so far have been happy with the purchase, quick delivery and initial performance of the tires. I hope to make a future purchase of three additional tires sometime in the future.

The shipping down to Albuquerque New Mexico was way faster then expected. The part fit like a glove and looks even better. The right part, at the right price. I WILL USE THESE GUYS IN THE FUTURE.

Excellent price and fast shipping. Product showed up as described and timely.
