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) 1300-00112 is a fuel pump repair kit engineered for Mercury and Mariner 2-cylinder 35 HP and 3-cylinder 60–70 HP outboard motors. Covering model years 1977–1980, 1982–1987, and 1989–1990, this kit provides a cost-effective alternative to full pump replacement, restoring proper fuel delivery and reliable engine performance.

Key Features:

  • Includes all components needed to rebuild the fuel pump: diaphragms, springs, check valves, and gaskets
  • Direct replacement for Mercury OEM part numbers 55278A4 and 55278A3
  • Cross-references with Sierra 18-7809 and GLM 40340
  • Designed for Mercury/Mariner 2-cyl 35 HP and 3-cyl 60–70 HP outboard fuel pumps
  • Covers model years: 1977–1980, 1982–1987, and 1989–1990
  • UPC: 840080473901

Over time, fuel pump diaphragms can develop cracks or pinholes that disrupt proper fuel flow, and internal check valves and springs can fail, leading to complete pump failure. This EMP repair kit addresses these common failure points, allowing for a straightforward rebuild rather than a full pump replacement. It is a reliable, direct-fit solution for maintaining the fuel system integrity of compatible Mercury and Mariner outboard engines.
