Performance & Real-World Benefits

The 806105Q1 bearing carrier anode plays a crucial role in keeping your drive’s lower unit protected. By attracting the corrosion that would otherwise attack vital metal components, it helps extend the life of your gear case, seals, and internal parts.

Its aluminum composition makes it lighter and longer-lasting than zinc, offering balanced protection in both fresh and saltwater. The included hardware simplifies installation, and replacing it annually (or when pitted) ensures your drive stays corrosion-free and performing at its best.

Why Choose Mercury OEM

The Quicksilver 806105Q1 is a genuine Mercury Marine part, designed specifically to protect your sterndrive the way Mercury intended. Aftermarket anodes can vary in composition and quality, often wearing unevenly or offering limited protection.

Mercury’s OEM aluminum alloy anodes are tested under real marine conditions to deliver predictable, long-term corrosion resistance. It’s the same level of protection Mercury builds into its new drives — proven, reliable, and trusted by boaters worldwide.
