Mercury GASKET OEM 8M0177107

Mercury Thermostat Gasket 8M0177107 is sold under the Quicksilver brand, Mercury Marine's line of replacement parts and accessories. This replacement gasket is designed to provide a proper seal at the thermostat housing on select Mercury 9.9-60 HP engines.

Compatible with select Mercury applications including:

• 9.9 HP
• 15 HP
• 20 HP
• 25 HP
• 30 HP
• 40 HP
• 50 HP
• 60 HP

The thermostat gasket seals the mating surfaces around the thermostat housing, helping prevent cooling-water leaks and maintain proper cooling-system operation. Thermostat gaskets should be inspected and replaced as needed whenever the thermostat or housing is removed for service.

Because Mercury uses different thermostat and cooling-system configurations within this horsepower range, compatibility should be confirmed using the engine serial number before ordering.

To Confirm Compatibility: Contact our team with your engine serial number at (727) 596-5929 before ordering.
