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 278AO3AM1 is a heavy-duty air mount boat seat mount from the 278 Air Series, engineered to deliver exceptional strength, stability, and smooth operation at the helm. Designed for use with 2-7/8" diameter pedestals, this mount is built to handle the demands of oversized helm seats with ease.

The 278 Air System incorporates a dampening gas spring that absorbs wave impact and hull vibration, reducing fatigue during long days on the water. A rigid mount construction combined with a wider seat interface creates maximum pedestal robustness, while the improved slider motion allows easy fore and aft seat adjustment. Added ribbing on the mount body and a positive locking mechanism deliver outstanding strength and on-water stability.

Key Features:

  • 3° tilt angle for ergonomic helm positioning
  • Compatible with 2-7/8" diameter Air Series pedestal posts
  • Short handle design for a compact, low-profile slider
  • Heavy-duty cast construction supports popular oversized helm seats
  • Dampening gas spring absorbs shock and impact
  • Reinforced ribs and positive lock for superior strength and stability
  • Standard 5" 4-hole mounting pattern for easy installation
  • For use with adjustable height pedestals

The Attwood 278 Air Series components are engineered exclusively for 278 Air models. Verify your pedestal series before ordering, as Air Series and Pro Series components are not interchangeable.
