B & S Anodes

<h3>Premium Marine Corrosion Protection Solutions</h3><p>B & S Anodes delivers specialized corrosion protection products designed to safeguard marine vessels, equipment, and underwater metal components from the destructive effects of electrolysis and galvanic corrosion. With roots in electrochemical engineering and cathodic protection technology, the brand has established itself as a trusted supplier of marine-grade protective anodes for boaters, shipyards, and marine maintenance professionals.</p><h3>Advanced Anode Technology for Marine Applications</h3><p>Marine environments present unique challenges for metal components. Saltwater acts as an electrolyte that accelerates galvanic corrosion, potentially causing thousands of dollars in damage to propellers, rudders, trim tabs, and through-hull fittings. B & S Anodes addresses these concerns by providing sacrificial anodes that corrode preferentially, protecting more valuable metal components from degradation. Their <a href="/7244-b-s-anodes-anodeszincs-200103">anodes and zincs</a> are engineered to meet the demanding requirements of saltwater, brackish water, and freshwater marine environments.</p><p>The company's product line reflects a deep understanding of electrochemical principles and marine corrosion science. Each anode is manufactured to provide consistent electrical potential and reliable sacrificial protection throughout its service life. Whether protecting an outboard motor, sterndrive, shaft, or rudder, proper anode selection and installation is critical to preventing costly corrosion damage.</p><h3>Comprehensive Protection Systems</h3><p>Beyond individual protective anodes, B & S Anodes offers complete <a href="/7244-b-s-anodes-anode-kits-200102">anode kits</a> that provide comprehensive corrosion protection for specific marine applications. These carefully assembled kits take the guesswork out of corrosion protection by including all necessary components for complete vessel protection. For marine professionals and boat owners who understand that proper maintenance extends vessel life and preserves resale value, having the right combination of anodes in the correct locations is essential.</p><p>The brand's expertise extends to specialized marine components, including precision-engineered parts like <a href="/7244-b-s-anodes-engine-rocker-arm-shaft-5680">engine rocker arm shafts</a>, demonstrating their broad technical capabilities in marine and industrial applications. This diverse product range reflects the company's engineering background in electrochemical systems and marine equipment manufacturing.</p><h3>Why Marine Corrosion Protection Matters</h3><p>Regular anode inspection and replacement is one of the most cost-effective maintenance practices for any vessel. Neglected or depleted anodes can lead to rapid deterioration of expensive components like propellers, shafts, and underwater metal fittings. B & S Anodes provides the protective solutions that help boat owners avoid emergency haul-outs, costly repairs, and premature component replacement, making proper corrosion protection an investment in long-term vessel integrity.</p>

Product Details

The B & S Anodes BSM118B is a donut-style collar zinc anode designed to provide sacrificial corrosion protection for propeller shafts and underwater metal components on boats. This 1-1/8 inch collar anode installs around the propeller shaft to prevent galvanic corrosion that can damage expensive marine hardware.

Key Features:

  • 1-1/8 inch inner diameter fits standard propeller shafts
  • Donut collar design for easy installation around shaft
  • Marine-grade zinc alloy provides superior corrosion protection
  • Sacrificial anode protects propellers, shafts, and rudders from galvanic corrosion
  • Suitable for saltwater and brackish water applications

Shaft collar anodes should be inspected regularly and replaced when approximately 50% of the material has been consumed. Proper anode maintenance is essential for protecting your boat's underwater metals and extending the life of expensive marine components.

so far so good

Quick and simple

So far so good.

Very good

Lowest price on the part i needed out of anyone online. Incredibly fast shipping, arrived in two days. Don't hesitate to buy from them. I'm now a customer for life.

My son lives about 1500 miles from me. He had asked me to get him an Industries SuperFlow Hi-Volume Air Compressor for Christmas. <br>With a couple of click on my computer, the compressor was ordered to be shipped to him and was paid for. He had the exact compressor he requested within five days.(and that included the weekend)<br>One word sums up my experience---EASY

Don't know yet. You haven't a chance to mess any thing up yet.

Great customer service, received tracking number quickly.

We looked a lot of places online for the steering stabilizer for our vehicle. We priced and looked to find out who had the best product and fastest shipping. We were so glad that Autoplicity was able to have just what we needed. We highly recommend that you visit autopicity.com for all you vehicle needs and we thank Autoplicity for their expediency in getting us our stabilizer.

The item has not been delivered yet. But the email updates are great. And I found this much cheaper than elsewere.
