<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 57-57502 is a dry joint exhaust riser with a 4" outside diameter and 7° down angle outlet, designed specifically for marine inboard engine exhaust systems. This riser is engineered for MerCruiser GM V6 and V8 engines (305, 350, and 377 cubic inch displacement) equipped with dry joint exhaust manifolds from model years 2002-2004.

Key Features:

  • 4" O.D. center rise outlet configuration
  • 7° down angle design for proper exhaust flow
  • Hot dipped and powder coated for superior corrosion protection
  • Precision-engineered replacement for OEM applications
  • Cast iron construction for durability in harsh marine environments

Application:

This dry joint riser fits MerCruiser GM V6 and V8 engines with 305, 350, and 377 CID displacement running serial numbers 0M600000 through 0W309999. The dry joint design provides improved sealing and reduced corrosion compared to traditional wet joint exhaust systems, making it ideal for saltwater and freshwater applications.

OEM Cross-Reference:

Replaces MerCruiser part number 864309T02 and other compatible aftermarket equivalents. Designed to meet or exceed OEM specifications for reliable performance and extended service life.

Important Note:

This riser is designed exclusively for dry joint exhaust systems and is not compatible with wet joint applications. Ensure your engine is equipped with a dry joint exhaust manifold before ordering.
