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 75-08675 Vernatherm is a precision thermal actuator designed for Johnson and Evinrude outboard engines. This component serves as the heart of the thermostat system, consisting of brass housing with an internal chamber containing a temperature-sensitive mixture that expands at a predetermined temperature. A piston fits into the chamber sealed with a rubber diaphragm, and as the waxy mixture expands from water heating up, it pushes upward on the piston to actuate the thermostat valve.

Key Features:

  • Fits Johnson/Evinrude 2-cylinder 9.9-15 HP, 3-cylinder 60-70 HP, 4-cylinder 120-140 HP, 6-cylinder 185-225 HP, and V8 275-300 HP outboard engines
  • Replaces OEM part numbers: Johnson/Evinrude/OMC/BRP 394411, GLM 13190, and Sierra 18-1506
  • Compatible with models from 1985-1995
  • Brass construction for durability and corrosion resistance
  • Precision-calibrated temperature activation

The vernatherm maintains accurate engine temperature by controlling the thermostat valve, which floats slightly open at steady speeds to increase or decrease cooling water flow as needed. This critical component ensures optimal engine performance, fuel efficiency, and prevents overheating in your Johnson or Evinrude outboard motor.

pretty snazzy

Quick and easy

easy to use website

Fair price

No issues - a bit slow, but otherwise OK

You guys beat all local auto part dealers in this area by far! I'm going to continue business with this company for a long time. Thank you very much for the savings!

reasonable prices and free ship

Autoplicity are great! Shipped out my order quick with good prices!

It was easy and the price is good, but this is just the order. If I get the product in the same manor, that will be great. Thanks, Mike

great!

A happy customer returns again

Autoplicity had fast shipping at a low price compared to other competitors. The price for the item itself was the lowest around so I think I got a good deal or my car. Would buy from again!
