EMP 75-75015 Thermostats & Parts Thermostat, 143-Degree, Mercury/Mariner 3-Cylinder Outboard The EMP 75-75015 is a 143-degree thermostat for 2004 and later Mercury and Mariner 3-cylinder outboards rated from 75 HP to 115 HP. The thermostat controls engine operating temperature by regulating coolant flow, and running the correct temperature rating for your engine matters for both performance and long-term reliability. Too cold and the engine runs rich and builds up carbon; too hot and you're looking at a much bigger problem. This thermostat is a direct replacement for Mercury OEM part 833072004 and is built to meet original equipment specifications for the application. It also crosses to the Sierra 18-3537 for buyers who are used to sourcing by Sierra part numbers. Fitment is specific to 2004 and later Mercury and Mariner 3-cylinder outboards in the 75-115 HP range. Confirm your engine's model year and cylinder count before ordering, as thermostat specifications vary across Mercury's outboard lineup. Fits: 2004 and later Mercury/Mariner 3-cylinder outboards, 75-115 HP Temperature rating: 143 degrees Replaces Mercury OEM: 833072004 Also crosses: Sierra 18-3537 Normalized SKU: 7575015UPC Code: 840080405896

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.

EMP 75-75519 Thermostats & Parts The EMP 75-75519 is a thermostat for Mercury and Mariner 4-stroke outboards in the 35 to 60 horsepower range. It fits the 35, 40, 50, and 60 horsepower models specifically, so confirming your exact engine horsepower rating before ordering is worth the extra moment. The thermostat regulates coolant flow through the engine to maintain the correct operating temperature. Running without a functioning thermostat, or with one that opens at the wrong temperature, pushes the engine outside its designed operating range and affects fuel efficiency, combustion quality, and long-term engine health. This thermostat replaces Mercury and Mercruiser part number 8M0117413 and Sierra part number 18-3640. EMP manufactures it to OEM specifications for correct opening temperature, flow characteristics, and physical fit on the listed applications.
