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>

Product Details

The Attwood Marine 99CC0451S carbon canister is designed to control fuel vapor emissions from marine fuel systems, meeting EPA and CARB evaporative emission requirements for gasoline-powered boats. This essential component captures fuel vapors from the fuel tank vent system, preventing them from escaping into the atmosphere while maintaining proper tank ventilation.

Key Features:

  • Trailerable vessel capacity: 70 gallons; Non-trailerable vessel capacity: 110 gallons
  • Fits standard 5/8-inch vent hose for easy integration with existing systems
  • Low permeation shell construction reduces overall system emissions
  • Compatible with ethanol-blended fuels (E10) for modern fuel system requirements
  • Can be mounted in any orientation using included mounting brackets for flexible installation
  • Engine compartment models feature pre-installed composite heat shield for protection and simplified installation

This carbon canister is an ideal solution for boat owners upgrading to meet emissions regulations or replacing existing vapor control equipment. The flexible mounting options and universal hose fitting make installation straightforward in tight marine engine compartments.

I was amazed at the fast delivery. I was going to cancel because I was sure about the part, but it worked perfectly and now my window is fixed. Very happy.

Good ordering experience thru their website, but all the good experience ended there. Never received any further communication from them about my order even after talking with a rep on the phone and sending an e-mail. The order did arrive and was what I needed. Will not do business with them again, had to be my worst internet purchase experience ever.
