Attwood Marine

<h3>About Attwood Marine</h3><p><strong>Attwood Marine</strong> has been a cornerstone of the boating world for over a century. Founded with a commitment to quality engineering and practical design, Attwood grew from manufacturing underwater hardware and on-deck fittings into one of the most recognized names across every segment of the marine accessories market. Today, the brand operates as part of the Navico Group by Brunswick — a global family of market-leading marine companies — yet it has never lost the focused, boater-first philosophy that built its reputation.</p><p>What sets Attwood apart is their end-to-end approach: they design, manufacture, test, and distribute their own products rather than simply resourcing components from third parties. Every product in their catalog is tested against the highest U.S. Coast Guard (USCG), American Boat and Yacht Council (ABYC), and CE standards, giving boaters and OEM boat builders alike the confidence that Attwood parts will perform when it matters most. Corrosion-resistant materials — including 304 and 316 stainless steel, chrome-plated zinc, and marine-grade synthetics — are used throughout the lineup to ensure durability in both freshwater and saltwater environments.</p><p>Attwood is also a leading OEM supplier, meaning you'll find their components pre-installed on boats straight from the factory. That pedigree speaks volumes: when boat manufacturers trust a brand to equip new vessels, that's a strong vote of confidence for the aftermarket buyer as well.</p><h3>Attwood Marine Product Categories</h3><p>Attwood's catalog spans a remarkably broad range of marine needs. On the docking and mooring side, their <a href="/7239-attwood-marine-fenders-201953">boat fenders</a> provide reliable hull protection against docks, pilings, and other vessels — an essential piece of gear for any boat owner. For on-water comfort and cockpit organization, Attwood's <a href="/7239-attwood-marine-seat-pedestal-packages-202496">seat &amp; pedestal packages</a> deliver complete seating system solutions backed by years of ergonomic engineering, while their <a href="/7239-attwood-marine-seat-clamp-mounts-202497">seat clamp mounts</a> and <a href="/7239-attwood-marine-seat-clamp-mounts-200927">mounting hardware</a> make swapping or positioning seats quick and secure. Rounding out the seating ecosystem, Attwood's broad selection of <a href="/7239-attwood-marine-seating-table-parts-accessories-202501">seating &amp; table parts and accessories</a> keeps every swivel, slide, and fitting performing at its best season after season.</p><p>Beyond seating and docking, Attwood is well known for its bilge and aerator pumps (including the iconic Sahara Mk2 and Tsunami series), navigation lighting, fuel systems, rod holders, and trailering accessories — making it a one-stop resource for outfitting or refreshing virtually any powerboat, fishing boat, or recreational vessel.</p><h3>Why Boaters Trust Attwood</h3><ul><li><strong>100+ years of marine expertise</strong> — a track record that few brands can match</li><li><strong>USCG, ABYC &amp; CE certified</strong> products built to rigorous safety and performance standards</li><li><strong>OEM-preferred supplier</strong> to leading boat manufacturers worldwide</li><li><strong>Corrosion-resistant construction</strong> engineered for saltwater and freshwater environments</li><li><strong>Full design-to-distribution control</strong> ensuring consistent quality across every product</li></ul>

The Attwood Marine 4801-7 S3 Digital Bilge Switch represents a significant advancement in automatic bilge pump control technology. Using proprietary electronic sensing technology, this 12-volt switch is engineered to operate reliably in any bilge water mixture without failure, including oil-contaminated water that causes traditional float switches to malfunction.

Key Features:

  • Advanced electronic sensing technology eliminates mechanical float mechanisms
  • Operates in any bilge water mixture including oil, detergents, and chemicals
  • Fully sealed electronics protected from water and chemical damage
  • Reduces continuous cycling to extend pump life
  • Can be mounted on flat surfaces or bulkheads in any orientation
  • No moving parts to stick, bind, or wear out
  • 12-volt DC operation compatible with standard marine electrical systems
  • Compact design fits in tight bilge spaces

The S3 Digital Bilge Switch eliminates the common problems associated with traditional float switches, such as sticking in oily water, false triggering from boat movement, and mechanical failure. Its solid-state design ensures consistent, reliable operation season after season, making it an ideal upgrade for any recreational or commercial vessel.

Google took me to your website. They had my hard to find part. Easy to use. Checkout was a snap. If this part is the 1 then this may be my new one and only parts store. LOWEST PRICES!

OK so far.

Shopping was easy. Shipping was fast the product quality was only issue but the problem was stuff I fixed.

Easy as pie.

As long as i recieve the part in a timely fashion this would be rated a five. Site is strange, had truck as vehicle (2000 tundra) and showed no parts, but typed in part # and they came up. Also, did not get 20% coupon code as intro stated.

Order several parts from Autoplicity for much less than the price I could find on any other site. With 3 days the first part was delivered to my door.<br><br>Excellent price and fast delivery time!

This website is very easy to shop on, it is easy to pay with amazon
