Attwood Marine

<h3>About Attwood Marine</h3><p><strong>Attwood Marine</strong> has been a cornerstone of the boating world for well over a century. <a href="/7239-attwood-marine">Founded in 1893</a>, the company began by manufacturing precision underwater hardware and on-deck fittings — rudders, struts, cleats, and lights — and quickly earned a reputation for fine engineering and enduring quality. After World War I, the brand's craftsmanship was so well regarded that legendary boatbuilder Chris-Craft turned to Attwood for brass fittings on their iconic pleasure boats.</p><p>Today, Attwood operates as part of the Navico Group by Brunswick, a global family of industry-leading marine companies, yet it has never lost the boater-first focus that built its name. What distinguishes Attwood from many competitors is their end-to-end philosophy: they design, manufacture, test, and distribute their own products rather than simply sourcing components from third parties. Every item in the Attwood catalog is rigorously tested to meet or exceed U.S. Coast Guard (USCG), American Boat and Yacht Council (ABYC), and CE standards — giving boaters and OEM manufacturers alike the confidence to rely on Attwood gear season after season.</p><h3>A Complete Marine Accessories Ecosystem</h3><p>Attwood's catalog spans an impressively broad range of marine needs. On the comfort and ergonomics side, their <a href="/7239-attwood-marine-seat-pedestal-packages-200926">Seat &amp; Pedestal Packages</a> deliver complete, ready-to-install seating system solutions backed by decades of engineering refinement. For boaters who prefer to build or customize their setup, Attwood's <a href="/200999-pedestals-fixed-mount-attwood-marine-7239">Fixed Mount Pedestals</a> provide a sturdy, reliable foundation engineered for lasting stability on the water.</p><p>When it comes to protecting your hull at the dock, Attwood's <a href="/7239-attwood-marine-fenders-200396">Fenders</a> offer dependable, marine-grade cushioning against docks, pilings, and other vessels — an often-overlooked but essential piece of gear for every boat owner. Getting on and off the boat safely is equally important, and Attwood's <a href="/200179-boarding-ladders-attwood-marine-7239">Boarding Ladders</a> are designed with heavy-duty construction, rated hardware, and user-friendly features to make every entry and exit as secure as possible.</p><p>Beyond these categories, Attwood is also widely recognized for its bilge and aerator pumps, navigation lighting, fuel systems, rod holders, and trailering accessories — making the brand a true one-stop resource for outfitting or refreshing virtually any powerboat, fishing boat, or recreational vessel.</p><h3>Why Boaters Choose Attwood</h3><ul style="list-style:disc"><li><strong>100+ Years of Proven Experience</strong> — A heritage of quality engineering stretching back to 1893.</li><li><strong>Multi-Standard Compliance</strong> — Products tested to USCG, ABYC, and CE standards for safety and performance.</li><li><strong>OEM-Trusted</strong> — A leading supplier to major boat manufacturers across a wide range of product categories.</li><li><strong>Corrosion-Resistant Materials</strong> — Extensive use of 304 and 316 stainless steel, chrome-plated zinc, and marine-grade synthetics built for harsh saltwater environments.</li><li><strong>In-House Engineering</strong> — Advanced prototyping, simulation, and real-world testing ensure reliability before any product reaches the water.</li></ul>

Product Details

The Attwood Marine 4202-7 automatic float switch provides reliable, hands-free bilge pump control for boats up to 12 volts. This durable switch activates your bilge pump automatically when water levels rise, ensuring your vessel stays dry without constant monitoring.

Key Features:

  • Mounts on any surface from horizontal up to a 24-degree angle for flexible installation
  • Durable wire leads that don't flex or hinge with the float, preventing premature failure
  • Integral cover dampens bilge sloshing and filters debris for reliable operation
  • Sealed switch construction resists moisture, fume ignition, and shock
  • 12-volt operation compatible with most marine bilge pump systems

Designed for marine environments, this float switch offers dependable automatic water detection to protect your boat from flooding. The sealed design ensures long-lasting performance even in harsh bilge conditions.

Great experience!!!!!!!

THANKS

Quick and easy.

Excellent transaction, received item very quickly and it was a lot cheaper than any other online retailer that I was able to find, could not even find cheaper on e bay.

I placed an order for Race Ramps and not only were they the best price I could find, but the shipping time was excellent as well!

I was told it would ship within 48 hours, when I called they told it was 24 business hours.. I think that they think we are morons... Price of items and chipping was really good.. Hope I get my stuff quickly..
