Mercury Poppet Valve Assembly
$110.97
Genuine Mercury Marine poppet valve assembly for selected Mercury and Mariner outboard engines. Regulates cooling water flow through the engine to maintain proper operating temperature and help prevent overheating. Suitable for many Verado and high-horsepower outboard applications.
The Mercury 8M0114707 Poppet Valve Assembly is a genuine OEM cooling system component designed for selected Mercury and Mariner outboard engines. The poppet valve plays a critical role in regulating cooling water flow through the engine, helping maintain the correct operating temperature across varying RPM ranges. At lower engine speeds, the valve restricts water flow to maintain proper engine temperature, while at higher RPM it opens to increase cooling capacity and prevent overheating.
Manufactured to Mercury Marine specifications, this assembly is built from corrosion-resistant materials and is designed to withstand the harsh marine environment. A worn or sticking poppet valve can cause fluctuating engine temperatures, overheating at idle or low RPM, and reduced cooling system efficiency. Replacing the valve helps restore proper cooling system performance and engine reliability.
The 8M0114707 assembly is commonly used on Mercury Verado and other high-horsepower outboard engines, including many 135–200HP L4 and 200–400HP L6 applications. Engine serial number verification is recommended before ordering to ensure correct fitment.
