Barraclough, Sr. under the name Marine Salvage, the company has spent nearly a century honing its expertise in marine engine component replacement. Today, Barr Marine by EDM holds a remarkable distinction: it is recognized as the last and only U.S. manufacturer of inboard marine parts in the world, offering the largest selection of inboard components available for immediate shipment.</p><p>From recreational boaters to professional marine technicians, Barr Marine has built its reputation on a customer-centered philosophy that prioritizes product knowledge, fast turnaround, and technical support. Orders placed by 3:00 PM Eastern Standard Time ship the same day, and toll-free technical support ensures that installers and DIYers alike can get the guidance they need to find the right part the first time.</p><h3>What Sets Barr Marine Apart</h3><p>Several qualities consistently distinguish Barr Marine from the competition in the marine aftermarket:</p><ul style="list-style:disc"><li><strong>Widest selection:</strong> Barr stocks an extensive catalog of hard-to-find inboard configurations, covering engine brands from MerCruiser and Volvo Penta to OMC, Crusader, Chris-Craft, Pleasurecraft, and many more.</li><li><strong>OEM-matched quality:</strong> Barr manifolds and risers are built to meet or exceed original equipment specifications, and Barr is the only manufacturer known to paint replacement components to match the original manufacturer&apos;s colors.</li><li><strong>Superior materials:</strong> Exhaust manifolds are crafted from high-quality cast iron with thicker interior walls for improved heat dissipation and long-term durability in demanding marine environments.</li><li><strong>3-Year Limited Warranty:</strong> All exhaust manifolds, risers, and exhaust connectors come backed by Barr&apos;s industry-leading warranty, and every kit includes the necessary mounting gaskets and hardware.</li><li><strong>World-wide distribution:</strong> From their facility in Natural Bridge Station, Virginia, Barr Marine ships parts globally while maintaining a 98 percent in-stock position across their catalog.</li></ul><h3>Barr Marine&apos;s Core Product Categories</h3><p>The heart of the Barr Marine lineup is its comprehensive range of Manifolds, Risers &amp; Elbows — the components most critical to the cooling and routing of exhaust gases in water-cooled inboard engines.
