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 27-27405 Powerhead Base Gasket is a precision-engineered sealing component designed for Johnson and Evinrude outboard motors. This gasket creates a critical seal between the powerhead assembly and the engine block, preventing water intrusion and maintaining proper compression within the combustion chamber.

Key Features:

  • High-quality construction using durable gasket material for reliable sealing
  • Designed to withstand the harsh marine environment and temperature extremes
  • Precision-cut to OEM specifications for proper fit and function
  • Essential component for powerhead rebuilds and major engine service
  • Helps maintain engine compression and prevents coolant leaks

This powerhead base gasket is a direct replacement part that ensures proper sealing between critical engine components. When performing powerhead service or rebuilds, replacing the base gasket with a fresh component is essential for preventing leaks and maintaining engine performance. The gasket should be installed on clean, flat surfaces without old gasket material residue for optimal sealing.

quick and easy

Great pricing!

fast and easy ordering process.

Very good. Had the items I needed whereas others did not.

I was extremely happy with the product that I received, I look forward to purchasing from autoplicity again very soon.

Went well, does it come with a spout?

Very good

Recommended by a fellow RegalGS member. Cheaper than Amazon. I haven't had the opportunity to put them on yet, but everything looks good.

Fantastic price ,fast shipping!!!!

Good price on parts, easy searching with Google Shopping, easy Checkout with Google Checkout. Wish the order shipped a day sooner. Called the 1-800 numnber, I get a little worried sometimes ordering car parts online - some sellers are bogus. But they answered the phone quickly and with a person in the US, not a machine or someone in another country.

sweet

Fast service even when shipping from the manufacturer. My product got to me in 3 days and it works great! Ordered an Odyssey PC1200 battery which was 20% cheaper than anyone else, with shipping included. Shipping information is a little slow on getting the tracking number, but their staff is efficient and friendly. Would definitely do business with them again.
