Engineered Marine Products

<h3>Engineered Marine Products: Marine-Grade Reliability for Automotive Systems</h3><p>Engineered Marine Products (EMP) brings precision engineering and marine-grade durability to the automotive aftermarket. With over 1,100 specialized components in their catalog, EMP applies the same rigorous standards required for harsh marine environments to create automotive parts that excel in demanding conditions. This manufacturer has built a reputation for producing components that withstand extreme temperatures, moisture, and vibration—qualities that translate directly to superior performance in automotive applications.</p><h3>Climate Control and Electrical Components</h3><p>One of EMP's core specialties lies in climate control system protection. Their <a href="/13199-engineered-marine-products-hvac-cut-off-switch-4209">HVAC cut-off switches</a> provide critical safety functions for heating and air conditioning systems, automatically interrupting power flow when pressure thresholds are exceeded. These switches serve as essential safeguards against compressor damage and system failures, making them indispensable for maintaining optimal cabin comfort and protecting expensive HVAC components from catastrophic failure.</p><h3>Transmission Control Technology</h3><p>Modern automatic transmissions rely on precise hydraulic control to manage gear changes smoothly and efficiently. EMP's <a href="/13199-engineered-marine-products-automatic-transmission-control-solenoid-7752">automatic transmission control solenoids</a> regulate transmission fluid pressure with exceptional accuracy, ensuring seamless shifts and optimal power delivery. These electro-hydraulic components play a vital role in transmission longevity, as proper solenoid function prevents harsh shifting, slippage, and premature wear of internal clutch packs and bands.</p><h3>Engine Cooling Solutions</h3><p>Maintaining proper engine temperature is fundamental to performance and longevity. EMP manufactures <a href="/13199-engineered-marine-products-engine-water-pump-2208">engine water pumps</a> that circulate coolant throughout the engine block, cylinder heads, and radiator system. Drawing on their marine heritage where cooling system reliability is non-negotiable, these water pumps feature durable construction with corrosion-resistant materials and precision-machined components. A failing water pump can lead to overheating and catastrophic engine damage, making quality replacement parts essential for any cooling system service.</p><h3>Engineering Philosophy</h3><p>What sets Engineered Marine Products apart is their commitment to over-engineering components for extreme conditions. Marine applications demand parts that can handle saltwater corrosion, constant vibration, and temperature fluctuations—challenges that also exist in automotive environments. This design philosophy results in parts with enhanced durability, longer service life, and greater reliability than standard replacement components. Whether you're servicing climate control systems, transmission repairs, or cooling system maintenance, EMP provides components engineered to exceed expectations.</p>

Product Details

The Engineered Marine Products (EMP) 46-46302 is a direct-replacement seawater pump assembly — also known as a raw water pump — designed for MerCruiser MCM/MIE inboard and sterndrive engines. This complete assembly ships with the pulley included, making it a ready-to-install solution for restoring proper raw water cooling performance.

Key Features:

  • Direct replacement seawater (raw water) pump assembly with pulley included
  • Designed for MerCruiser MCM/MIE 4.3L, 5.0L, 5.7L, and 6.2L MPI engines with ECM 555
  • Cast brass pump body for superior corrosion resistance in both fresh and saltwater environments
  • Neoprene impeller for reliable water transfer
  • Stainless steel shaft and fittings for long-term durability
  • Steel ball bearing construction

Replaces OEM Part Numbers:

  • Quicksilver / Mercury Marine: 46-8M0137216, 46-862914T10, 46-8M0139995

The EMP 46-46302 seawater pump assembly is a high-quality aftermarket alternative to OEM Quicksilver components, engineered to meet or exceed original specifications. Proper raw water pump function is critical to engine cooling — replacing a worn or failing pump helps prevent overheating and costly engine damage.
