Engineered Marine Products

<h3>About Engineered Marine Products (EMP)</h3><p><strong>Engineered Marine Products</strong>, widely known in the boating world as <strong>EMP</strong>, has been a trusted name in marine parts manufacturing for over 40 years. The company supplies OEMs, distributors, dealers, and rebuilders worldwide with high-quality aftermarket components engineered to meet or exceed original equipment manufacturer (OEM) specifications. Whether you maintain a weekend fishing boat or a performance inboard, EMP&apos;s extensive catalog is built to keep marine engines running reliably season after season.</p><h3>A Marine Parts Specialist Built on Engineering Precision</h3><p>EMP&apos;s foundation is precision manufacturing. Their design and production processes leverage modern engineering technology, with a focus on dimensional accuracy, material quality, and long-term durability in the demanding marine environment. Salt spray, constant vibration, wide temperature swings, and moisture ingress are realities every marine component must survive — and EMP engineers its parts with exactly those conditions in mind.</p><p>The brand&apos;s catalog spans a remarkably wide range of marine engine subsystems. From cooling and fuel delivery to gearcases, propellers, transom components, and steering systems, EMP offers solutions for outboard engines from manufacturers including Mercury/Mariner, Yamaha, BRP (Johnson/Evinrude), and Force, as well as inboard/sterndrive platforms such as MerCruiser, OMC, and Volvo Penta.</p><h3>Ignition and Electrical Components</h3><p>One of EMP&apos;s most comprehensive product areas is marine ignition and electrical systems. Their <a href="/13199-engineered-marine-products-ignition-control-module-10488">Ignition Control Modules</a> and related ignition components cover a broad spectrum of inboard and outboard applications — from distributor caps and rotors for Volvo Penta V8 engines to ignition coil assemblies compatible with MerCruiser 3.0L through 8.4L GM-based powerplants and OMC configurations. Reliable spark delivery is critical to engine performance and starting consistency on the water, and EMP&apos;s ignition lineup is designed to deliver dependable output across the entire RPM range.</p><h3>Gaskets, Seals, and Engine Integrity</h3><p>Keeping a marine engine leak-free is just as important as keeping it firing correctly. EMP&apos;s <a href="/13199-engineered-marine-products-gaskets-seals-201268">Gaskets &amp; Seals</a> lineup addresses the full range of engine and gearcase sealing needs — including gearcase seal kits, Teflon lip seals, fuel injector crush ring kits, and comprehensive engine gasket sets. Proper sealing prevents water intrusion, oil loss, and exhaust leaks that can quickly sideline a boat and lead to expensive engine damage.</p><h3>Why Boaters and Technicians Choose EMP</h3><ul style="list-style:disc"><li><strong>OEM-Grade Quality:</strong> Parts are engineered to meet or exceed original manufacturer specifications, ensuring proper fit and reliable function.</li><li><strong>Broad Application Coverage:</strong> EMP covers major outboard and inboard/sterndrive platforms from leading marine engine brands.</li><li><strong>Trusted Supply Chain:</strong> EMP products are sold through OEMs, distributors, and dealers globally, reflecting deep industry confidence in the brand.</li><li><strong>40+ Years of Manufacturing Heritage:</strong> Decades of marine-specific engineering experience inform every product in the EMP lineup.</li></ul><p>For boat owners, marine technicians, and engine rebuilders who demand components they can count on, Engineered Marine Products delivers the quality and application coverage to get the job done right.</p>

Product Details

The Engineered Marine Products 47-02373 is a replacement water pump impeller designed specifically for OMC Cobra sterndrive applications. This critical cooling system component ensures proper water circulation through your marine engine to prevent overheating and maintain optimal operating temperatures.

Key Features:

  • 10-blade design for superior water flow and cooling efficiency
  • Constructed from durable neoprene rubber for long-lasting performance
  • Features special hub design for secure installation
  • Engineered to meet OEM specifications for reliable fitment

Applications:

  • OMC Cobra, King Cobra, and Cobra SX sterndrives (1986-1993)
  • 4-cylinder engines: 2.3L to 3.0L
  • V6 engines: 4.6L
  • V8 engines: 5.0L to 7.5L

Regular impeller replacement is essential marine engine maintenance. Most manufacturers recommend inspecting impellers annually and replacing them every 1-2 years or 200-300 hours of operation. Signs of impeller failure include weak water flow from the tell-tale outlet, engine overheating, or visible blade damage. Always use proper lubricants during installation and never use petroleum-based products on neoprene impellers.
