      Mercury Outboard Thermostats and Gaskets

      When it comes to your Mercury Outboard, thermostats are an important part for controlling the temperature of your engine. As the temperature rises, the thermostat opens and allows cooling water to flow through the outboard. Keep your outboard from overheating with our selection of Mercury Outboard thermostat kits, thermostats, and gaskets. We carry the Sierra aftermarket parts, all of which meet OEM specifications.
