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>

This was a great seller, I chose them because they had the lowest price with incredibly low shipping for the item I purchased. It arrived on time and in great shape thanks to UPS. The product was the one that was described and it fit perfectly (exhaust). I will definitely be checking back for great deals and service. 10 out of 10!!!

Good

Quick and easy. I would like a little more confirmation before the order was actually sent. Also, an estimated ship time would be nice. But other than that this was very trouble free. Thanks

Great price

Quick and easy and the best prices around the net thanks. Very Happy.

Definitely the lowest price! Quick shipping, and great communication and follow-through.

Great price on name brand parts. Quick shipping. Will use again for my next order of parts.

I was searching for spark plugs and came across their web site and was surprised to see they had the cheapest price on the plugs I needed.

Got my order fast and everything was correct. Thanks for the good deal, just need some rear ones next.

Great prices and great communication!!
