OMC

<h3>About OMC &mdash; Outboard Marine Corporation</h3><p><strong>Outboard Marine Corporation (OMC)</strong> is one of the most storied names in recreational boating history. Tracing its roots to the early days of outboard engine manufacturing, OMC was formally established in 1929 when ELTO merged with Lockwood-Ash Motor Company, and officially adopted the OMC name in 1956. At its peak, OMC was the world&apos;s largest manufacturer and supplier of outboard motors, producing legendary powerplants under the Johnson and Evinrude brand names that powered millions of boats across the globe.</p><p>Headquartered in Waukegan, Illinois, OMC grew into a multibillion-dollar Fortune 500 corporation with an enormous footprint in both the outboard motor and powerboat markets. The company&apos;s engineering expertise extended far beyond engines &mdash; OMC owned a diverse portfolio of boat brands including Chris-Craft, Lowe Boats, Four Winns, Stratos, and Javelin, making it a true powerhouse of the marine industry. At its height, OMC commanded roughly one-third of the entire outboard motor market.</p><h3>OEM-Quality OMC Engine Parts</h3><p>For boaters who own or restore Johnson- and Evinrude-powered watercraft, genuine and direct-replacement OMC parts remain essential for maintaining reliability on the water. The OMC parts catalog spans the critical systems that keep an outboard or sterndrive running at its best &mdash; from the fuel delivery system all the way through to the ignition and electrical components.</p><p>At the heart of any outboard engine&apos;s reliability is its fuel delivery system. OMC <a href="/201310-fuel-pumps-omc-2994">fuel pumps</a> are engineered to deliver consistent fuel flow to the carburetor or injectors under the demanding conditions of marine use, where vibration, heat, and humidity can take a toll on lesser components. Paired with the right carburetor kits and fuel pump rebuild kits, these parts allow boaters and technicians to restore factory fuel delivery performance without a full engine overhaul.</p><p>Electrical reliability is equally important on the water, where a no-start situation can leave you stranded far from the dock. OMC <a href="/200974-solenoids-omc-2994">solenoids</a> play a critical role in the starting circuit, directing high-amperage current to the starter motor when the key is turned. Equally important to the electrical system, the <a href="/15557-ignition-power-pack-omc-2994">ignition power pack</a> serves as the brain of the OMC ignition system, precisely timing spark delivery to keep combustion efficient and the engine running smoothly across the RPM range.</p><p>Proper engine mounting is also fundamental to safe, vibration-free boating. OMC motor mounts isolate engine vibration from the hull, protecting both the boat&apos;s structure and onboard electronics from the constant stresses of marine engine operation.</p><h3>A Legacy Worth Preserving</h3><p>Although Outboard Marine Corporation ceased operations in 2000 &mdash; with its Johnson and Evinrude brands subsequently acquired by Bombardier Recreational Products &mdash; the vast number of OMC-powered boats still on the water means that demand for these parts remains strong. Whether you&apos;re restoring a classic outboard or simply maintaining a well-loved boat, sourcing the correct OMC components ensures your engine performs the way it was designed to.</p>
