B & S Anodes

<h3>About B&amp;S Marine Anodes</h3><p>When it comes to protecting a boat from the relentless threat of galvanic corrosion, few names carry as much history or credibility as <strong>B&amp;S Marine Anodes</strong>. Rooted in the traditions of Bossler &amp; Sweezey — a Long Island propeller shop whose founders began hand-pouring zinc anodes in the 1960s — the brand has spent nearly 50 years refining one of the most important, yet often overlooked, aspects of marine maintenance.</p><p>Galvanic corrosion occurs when dissimilar metals in contact with saltwater create an electrochemical reaction that eats away critical underwater components like propellers, shafts, rudders, and struts. The solution is elegantly simple: attach a sacrificial metal that is less &quot;noble&quot; than the parts you want to protect, so it corrodes first. That metal is the anode — and not all anodes are created equal.</p><h3>Hand-Poured, Mil-Spec Quality</h3><p>What sets B&amp;S apart is a commitment to craftsmanship that has never wavered. Every zinc anode in the B&amp;S lineup is hand-poured at their Long Island, NY facility and cast from a zinc alloy that meets Military Specification MIL-A-18001K. This hand-pouring process produces a higher degree of porosity than die-cast alternatives, resulting in a greater surface area exposed to the water. The practical effect: B&amp;S anodes dissolve more evenly and completely, delivering consistent, long-lasting protection throughout the boating season. Die-cast anodes, by contrast, are prone to uneven erosion and can develop passive surface layers that reduce their effectiveness.</p><p>For boaters operating in saltwater, B&amp;S zinc anodes are the flagship choice. The brand also offers aluminum anodes for applications where engine manufacturers require them, particularly for boats still under warranty, as well as magnesium anodes for freshwater environments — giving boaters the right material for their specific conditions.</p><h3>Anode Kits for Mercury &amp; MerCruiser Outdrives</h3><p>Beyond individual anodes, B&amp;S offers comprehensive anode kits engineered for popular Mercury and MerCruiser sterndrive systems, including Bravo and Alpha series outdrives. These kits bundle all the necessary anodes and hardware needed for a complete corrosion protection job, taking the guesswork out of which individual pieces to buy. For boaters who service their own vessels, a B&amp;S kit is an efficient, reliable way to ensure every vulnerable point on a drive unit is properly protected at once.</p><h3>A Legacy of Innovation and Trust</h3><p>In 2005, B&amp;S Marine Anodes was formally established as its own dedicated manufacturing entity, allowing the brand to focus exclusively on anode production and quality control. That singular focus shows in the product. B&amp;S continuously reviews new applications for anode use across both pleasure craft and commercial vessels, staying ahead of an ever-evolving boating industry. Whether you are protecting a weekend runabout or a working commercial hull, B&amp;S Marine Anodes delivers the kind of proven, made-in-the-USA protection that serious boaters have relied on for generations.</p>
