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 12-02668 is a brass castle washer designed for securing propeller hardware on Mercury and Mercruiser marine engines. This precision-engineered locking washer provides a mechanical barrier to prevent propeller nuts from loosening during operation.

Key Features:

  • Constructed from corrosion-resistant brass material for marine environments
  • Castle design with notches that engage with locking mechanisms to prevent rotation
  • Fits between the propeller nut and mating surface for secure fastening
  • Designed for splined rubber hub propellers (non-Flo-Torq II applications)
  • Tabs are bent around the nut after installation to lock the assembly in place

Application: Compatible with Mercury/Mariner 135-275 HP (V6 2-cycle) outboards, Alpha drives, and Bravo I drives without Flo-Torq II hubs. This washer replaces OEM part numbers 12-31211, 12-31211A2, 12-31211A3, 12-31211Q03, and cross-references with Sierra 18-3714, GLM 21360, and Mallory 9-73902.

Engineered Marine Products manufactures quality marine engine components using advanced technology and precision manufacturing processes, backed by over 40 years of industry experience.
