B & S Anodes BSM312SL 3-1/2 Inch Streamline Shaft Zinc Anode

Manufacturer

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 BSM312SL is a hand-poured, mil-spec zinc anode designed to protect propeller shafts and other critical underwater components from galvanic corrosion in saltwater applications. This streamlined zinc collar fits on the propeller shaft of inboard motors and helps combat electrolysis.

Key Features:

  • Crafted from zinc alloy meeting Military Specification MIL-A-18001K with hand-poured construction for higher porosity and more even erosion
  • Supplied with stainless steel allen head bolts for secure mounting
  • 3-1/2 inch shaft diameter streamline design
  • Designed specifically for saltwater use where zinc anodes are most effective
  • Made in the USA on Long Island

As a sacrificial anode, this zinc protects vital boat parts like propellers and shafts from saltwater corrosion by corroding in place of critical metals. Replace your anodes when they appear to be half their original size, typically every 6-month season.

Great

Very pleased, affordable price and quick checkout.

Pricing is enticing

I have been looking for rain guards for my car for 6 months now I finally found hem fast and easy check out :)

so far so good

I had a great experience ordering my springs through Autoplicity. I received instant notification of my order as it was placed. I was very happy to see shipping information so quickly after the order was placed, also. Last, but not least, I received the springs SO FAST! Best price, instant notification of order status, fastest shipping, therefore best review that I can write! Thanks, Autoplicity, I will be a return customer if I need anything else!

easy website to use

Was a whole lot faster and easier than other websites. Also a whole lot cheaper!! Good job

Everything was great just the returning could use help. The first ine i ordered was wrong and shipping back to you is more costly than i hoped.

So far So good. Like Low Price guarantee and paying through amazon

I ordered the part from Autoplicity and it arrived in time and is a great product<br>

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Easy to purchase online.Would buy from again. Fast shipping.
