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 300-76382 is a high-quality voltage rectifier/regulator designed for Mercury and Mariner outboard motors. This essential charging system component regulates voltage to ensure proper battery charging and maintains stable electrical system performance in marine applications.

Key Features:

  • Converts AC voltage from the alternator to DC voltage for battery charging
  • Maintains fixed battery voltages to prevent overcharging and electrical system damage
  • Compatible with 1976 and later Mercury/Mariner outboards
  • Fits 2-cylinder 30-40 HP, 3-cylinder 40-90 HP, 4-cylinder 100-125 HP, and V6 135-200 HP models
  • Direct OEM replacement part
  • Lightweight design at 0.45 lbs for easy installation

OEM Part Number Cross-Reference:

Replaces Mercury part numbers 8M0084173, 883072T, 854515T1, 854515, 8301792, 8152795, 815279T, and 8152793. This ensures compatibility with a wide range of Mercury and Mariner outboard applications.

Symptoms of Faulty Regulator/Rectifier:

Poor engine starting, dimmed headlights, and fluctuating voltage meter readings may indicate a failing rectifier/regulator. This component is critical for preventing battery damage caused by improper charging voltages.

Engineered Marine Products (EMP) has over 40 years of experience providing reliable, competitively-priced marine electrical components for both OEM and aftermarket applications.

The refrigerator was at my home in 3 days!!! Was 300 dollars cheaper than even Amazon and just a quick getting it. Far exceeded my expectations and will absolutely order from them again. It was bought to replace a furrion 10cu ft fridge that gave out after a year and 4 months, very disappointing. The fit was right on the sides but did not have to trim anything to fit it in and the layout of the inside is much better than the furrion. I ordered the mounting brackets and sour patch thru a different company and still have not received them.

:)

good
