EMP 27-27605 Thermostats & Parts
The EMP 27-27605 is a thermostat gasket for Mercury and Mariner 3-cylinder outboards from 30 to 60 horsepower, covering two production windows: 1991 to 1993 and 1999 to 2006. The gap between those ranges is not a typo, so verifying your model year before ordering is important. The thermostat gasket seals the thermostat housing to the engine, preventing coolant from bypassing the thermostat or leaking at the housing joint. Any time the thermostat housing is removed for service or thermostat replacement, this gasket should be replaced. A reused gasket that has been heat-cycled through multiple seasons will not seal as reliably as a fresh one.
This gasket replaces Mercury part number 8128672 and crosses with Sierra 18-2729 and GLM 35090. EMP manufactures it to OEM specifications for correct material, thickness, and sealing performance on the listed applications.

EMP 27-27609 Thermostats & Parts
The EMP 27-27609 is a thermostat gasket for Mercury and Mariner 3-cylinder outboards from 30 to 60 horsepower. Fitment covers model years 1997 to 2005 and 2010. The production window is specific and includes a gap followed by a single model year at the end, so confirming your exact model year before ordering is worth the extra moment. This gasket seals the thermostat housing to the engine, preventing coolant from bypassing the thermostat or escaping at the housing joint. Replace it any time the thermostat housing is removed, as a previously compressed and heat-cycled gasket will not provide the same seal as a new one.
This gasket replaces Mercury part number 827284 and crosses with Sierra 18-2721, GLM 37850, and Mallory 9-72420. EMP manufactures it to OEM specifications for correct material, thickness, and sealing performance on the listed applications.
