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 1399-39021 is a preventive maintenance service valve designed for Johnson and Evinrude 2-stroke outboard motors. This service valve enables the use of fogging oil or engine tuner through the primer solenoid system without requiring removal of the air silencer cover, making routine maintenance more convenient.

Key Features:

  • Includes O-ring for proper sealing and leak-free operation
  • Converts electric primer to through-the-primer preventive maintenance system
  • Maintains both electrical primer operation and backup manual primer function
  • Designed for 1990 and earlier Johnson and Evinrude outboards
  • Aftermarket replacement engineered to meet OEM specifications

Cross-Reference Part Numbers:

  • OEM BRP/Johnson/Evinrude: 175158, 0175158, 765749
  • Sierra Marine: 18-0871, 18-0871-1, 18-7044

This valve allows you to perform preventive maintenance procedures such as engine fogging and tuning without disassembling carburetor components. Note that this is the manual valve only and does not include a spray can. For complete installation, injection hose part 0769014 may be required separately.

I would have liked better clarification on part ordered and shipping time. Also on the replacement part, filler neck, the vent tube had a slightly larger flare at the end which was nearly impossible to fit in the OEM fuel vent hose.

Until this it was pretty good. However I do not appreciate being forced to fill out this survey and add in information that I previously submitted....

Easy to order. Good prices on shipping.

Very good, liked that I could pay with Amazon.

So I left a review already about autoplicity and it was before I even checked when it was going to be delivered. I was happy to see it was already shipped but even more excited and pleased to see that it was only going to take two days to get here! Scheduled for delivery tomorrow! Could not be any happier with this company!
