EMP 515621 Thermostats & Parts A thermostat is one of those small parts that does a big job, and when it fails, your engine temperature goes sideways fast. This EMP 160-degree thermostat is a direct-fit replacement for Marine Power 6.0L, 6.2L LS3, and LSA engines. It opens at 160 degrees Fahrenheit, which is the correct operating temperature for these engine families, keeping coolant flow regulated and engine temps where they need to be for reliable performance on the water. Built to OEM specifications, this thermostat replaces Marine Power 515621 directly with no modifications required. If your engine is running hot, slow to warm up, or showing erratic temperature readings, a failed thermostat is one of the first things to check. Swapping it out is a straightforward job and this part gets you back to the correct spec.

Mercury Marine 8M0070213 Thermostats & Parts The poppet valve assembly plays a critical role in how your Mercury outboard manages cooling water pressure and flow. The Mercury Marine 8M0070213 Poppet Valve Assembly is a genuine OEM replacement that restores proper pressure regulation in the cooling system, keeping water circulating at the right pressure through the engine block and powerhead. On Mercury outboards, the poppet valve regulates the pressure of raw water flowing through the cooling system. It opens and closes in response to water pressure changes, ensuring the engine receives adequate cooling flow at all RPM ranges while preventing over-pressurization that could damage seals and gaskets. When the poppet valve wears or fails, the symptoms can include overheating at higher RPMs, inconsistent water pressure at the tell-tale, or cooling system behavior that just does not feel right underway. It is a component that works constantly and quietly, and its condition directly affects how well the entire cooling system performs. As a genuine Mercury Marine OEM assembly, the 8M0070213 is built to the exact specifications Mercury engineers into their cooling systems. The valve seat, spring tension, and sealing surfaces are all matched to the original design, ensuring the assembly opens and closes at the correct pressure thresholds for your engine. Aftermarket poppet valves may fit the port, but pressure calibration differences can compromise cooling performance in ways that are difficult to diagnose until real damage has occurred. Key Features: Genuine Mercury Marine OEM poppet valve assembly Part Number: 8M0070213 Regulates raw water pressure in Mercury outboard cooling systems OEM valve seat, spring tension, and sealing surface specifications Direct replacement with no modification required Confirm your engine model and serial number before ordering. Mercury poppet valve assemblies are application-specific, and verifying the correct part number for your engine ensures proper pressure calibration and a clean installation.
