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.

Everything is good except for one price that I saw on your page. It is for the Stillen Big Brake kit 30-7050. I got very excited cause it said 183.00 and came to find out it is an error. Would be nice if you guys would follow up on this. Thanks anyways.

Excellent service and communication.

Saved me $150 over Mopar brand fan assembly for my 2005 300C 5.7 HEMI. Delivery was extremely quick, the part was a perfect fit, and working as expected. Thank you!!!
