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 (EMP) 47-09215 is a replacement water pump impeller designed to meet or exceed OEM specifications for marine cooling system applications. EMP impellers are precision-engineered from durable rubber compounds to deliver reliable coolant flow and protect your engine from overheating in both freshwater and saltwater environments.

Key Features:

  • Engineered to meet or exceed original equipment manufacturer (OEM) specifications
  • Constructed from high-grade rubber for long-lasting flexibility and durability
  • Designed to fit snugly within the water pump housing for optimal sealing and flow
  • Suitable for use in demanding saltwater and freshwater marine conditions
  • Direct-fit replacement for simplified installation

Regular impeller replacement is a critical part of marine engine maintenance. Impeller blades can stiffen, crack, or shed over time—especially if the engine sits unused for extended periods—leading to reduced coolant flow and potential engine damage. Replacing the impeller at recommended service intervals helps ensure consistent cooling performance and long engine life.

I like your site because I don't have to logon with an id &amp; password with my personal info . I can just make a purchase as a guest. that's why I don't use amazon

Easy to shop and good price. Hope shipping is fast.

I like turtles. Nice site.

Good

Easy site to use

Easy shopping, however the confirmation from the warehouse and then the shipment to my home, took a week. For an overall product purchase it's fine, but if you have your car broken and you are waiting for the part, the waiting time is terrible.

easy shopping!

I like the the eade and preice

Great

I hope this time there will be no problem or cancellation of my order from your end, as I confirmed the stock from your sale department personnel (Hector) before I proceed on checking out.

I was looking for KC lights for my jeep, not only CI they have just the ones I was looking for, they were half the price of any local auto shop! Shipping costs were very low to. Thanks!

Ordered my parts on 4/18 and received them on 4/20. Very fast service! Would recommend buying from Autoplicity to anyone and everyone!
