<h3>About OMC: A Legacy of Marine Engine Excellence</h3><p>Outboard Marine Corporation&mdash;better known as <strong>OMC</strong>&mdash;stands as one of the most storied names in recreational boating. Built on decades of engineering innovation, OMC became the parent company behind iconic marine brands including Johnson and Evinrude, and produced a wide range of sterndrives and inboard engines that powered countless boats across North America and beyond. Their commitment to purpose-built marine engineering meant every component&mdash;from powerheads to filtration systems&mdash;was designed to withstand the unique demands of life on the water.</p><p>Unlike automotive engines that typically start daily and operate under relatively predictable conditions, marine engines face a far harsher set of challenges. Extended idle periods, wide RPM swings, saltwater corrosion, vibration from wave shock, and high-heat operating cycles all conspire to break down engine oil and clog fuel systems faster than their land-based counterparts. That&apos;s precisely why OMC developed its own line of OEM filtration components&mdash;parts engineered specifically to the tolerances and demands of their sterndrive and inboard platforms.</p><h3>OMC Filtration: Built for the Marine Environment</h3><p>At the heart of any well-maintained marine engine is a clean lubrication system. OMC&apos;s <a href="/2994-omc-engine-oil-filter-5340">Engine Oil Filters</a> were designed with marine-grade construction in mind, featuring metal end caps sealed to the filter element, anti-drain-back valves to prevent dry starts after long layups, and resin-impregnated filter media capable of capturing harmful combustion byproducts. OEM part numbers like 502900, 502901, and 502903 covered a broad range of OMC sterndrive and inboard applications&mdash;from inline four-cylinder GM blocks to big-block V8 configurations.</p><p>Maintaining a clean fuel supply is equally critical on the water, where a clogged or failing <a href="/2994-omc-fuel-filter-6200">Fuel Filter</a> can leave you stranded far from shore. OMC offered OEM fuel filters and water-separating filter kits engineered to remove contaminants and moisture before they could reach the carburetor or injection system. With OEM part numbers cross-referencing across major marine platforms, finding the right OMC fuel filter for your application is straightforward.</p><p>Whether you&apos;re performing a routine seasonal service on an OMC Cobra sterndrive or refreshing the filtration on an older OMC inboard, sticking with OEM-spec Oil Filters ensures you&apos;re meeting the original engineering tolerances the engine was designed around. OMC filter specifications were also widely cross-referenced with MerCruiser and Volvo Penta platforms, making them a trusted choice for multi-brand service shops.</p><h3>Why Choose OEM OMC Filtration Parts?</h3><ul><li><strong>Exact-fit engineering:</strong> Designed to match the thread pitch, gasket diameter, and canister length specified for each OMC engine variant.</li><li><strong>Marine-grade construction:</strong> Built to resist corrosion and maintain a reliable seal in humid, salt-laden bilge environments.</li><li><strong>Broad application coverage:</strong> Covers a wide range of OMC sterndrive and inboard engines, from 2.5L four-cylinders through V8 big blocks.</li><li><strong>Trusted cross-reference:</strong> OMC part numbers are widely documented, making it easy to find confirmed-fit replacements and aftermarket equivalents.</li></ul><p>For any boater looking to preserve the longevity and performance of an OMC-powered vessel, sourcing the correct <a href="/2994-omc-oil-filters-201278">oil filters</a> and fuel filtration components is one of the most cost-effective maintenance decisions you can make. Explore the full selection of OMC filtration parts to keep your engine protected season after season.</p>

Fast delivery and great product

Wasn't happy with the extra charges for handling. Do not see that until I paid it.

Found exact part i needed and price reasonable, I paid extra for 2day shipping and it was on time, I would order parts from boatpility again.

Service and support were great, order arrived quickly and in good shape.

Grate customer service

Super smooth transaction, and fast delivery. Just waiting for my mechanic to open packages and verify all correct parts, but I don't expect any issues. Would definitely purchase and recommend others do business with Motorsport.com again
