<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.

Product Details

The Engineered Marine Products 47-01920 is a replacement impeller designed for marine water pump applications. Impellers are critical rotating components within raw water cooling pumps, responsible for circulating water through the engine's cooling system to prevent overheating. Replacing a worn or damaged impeller at regular service intervals is essential for maintaining optimal engine performance and longevity.

Key Features:

  • Direct-fit replacement impeller for compatible marine water pumps
  • Engineered for reliable raw water flow and consistent cooling performance
  • Manufactured to meet or exceed OEM specifications
  • Constructed from flexible, durable rubber compound designed to withstand saltwater and freshwater environments
  • Part of the trusted Engineered Marine Products line of marine cooling system components

Regular impeller replacement is recommended as part of routine marine engine maintenance. A failed impeller can result in loss of cooling water flow, leading to engine overheating and costly damage. The 47-01920 impeller is a straightforward service part suitable for do-it-yourself installation.
