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>

Key Features:

  • 120-degree temperature rating for reliable cooling system operation
  • Complete kit includes thermostat and necessary gaskets for proper installation
  • Direct replacement for Mercury part number 803061T1
  • Cross-references with Sierra 18-3569 and GLM 13124
  • Precision-engineered to meet OEM specifications
  • Durable construction designed to withstand harsh marine environments

Application Coverage:

  • 3-Cylinder Models: 70 HP (Serial Number 0A996142 & Up), 75 HP (Serial Number 0C222000 & Up), 80 HP (Serial Number 0A996142 & Up), 90 HP (Serial Number 0A996142 & Up)
  • 4-Cylinder Models: 100 HP (Serial Number 0B209468 & Up), 115 HP (Serial Number 0C100000 & Up), 125 HP (Serial Number 0D283222 & Up)

Regular thermostat maintenance is crucial for outboard engine longevity. Thermostats can fail due to corrosion, sticking, or exposure to extremely high temperatures. Replacing the thermostat after an engine overheat incident is highly recommended to prevent future cooling system issues.

Great

good price

first time buyer...let's hope it's as good as it sounds.

Quick online process

Autoplicity came thru again with a price that was a fraction of the parts store's! We don't need the whole assembly...just this back side. Excellent internet outfit to deal with. This part will save a 2001 Ford Escape with 212K miles on it..

I purchased a BakFlip F1 truck bed cover, they had the best price I could find anywhere. Their shipping process is very fast. I will look to buy from them again.

Real good prices

had an obscure part for my old truck. quick affordable shipping, fair prices, Great!

Great,easy to use service!

Order took a few days to ship but when it did it arrived fast.

Great prices.

All good
