Mercruiser uses a sleeve in some of their thermostat housings. These parts must be installed properly or the engine may overheat. Please note: Thermostat element temperatures vary from engine manufacturers. Typically a raw-water cooled engine uses temperature ranges of 140-145 degrees F up until 1995 and 160 degrees F from that point until now. Fresh-water cooled engines typically use a range of 160-165 degrees. Most automotive thermostats range from 185-210 degrees and should not be used in marine applications. Always consult your marine engine dealer for the correct thermostat for your application. Misapplication or mis-installation of thermostat element will cause overheating problems.
