Mercury & Quicksilver Thermostats

(28 products)
View as

Shop Mercury and Quicksilver marine thermostats, thermostat kits and housing seals for the engine applications identified on each listing. This range includes Mercury outboards, MerCruiser engines and Quicksilver replacements for selected Yamaha, Johnson, Evinrude and OMC outboards.

Choose by engine and temperature rating

Match the manufacturer part number, engine model and serial number. Standard- and closed-cooling systems can require different thermostats, and a shared horsepower rating does not establish compatibility. Check whether your selected item includes a housing, gasket or installation seal.
