This Quicksilver kit pairs a 140°F thermostat with a cork gasket, sold as a 2-piece set under part 59078T3. It is aimed at older MerCruiser engines of the inline 4- and 6-cylinder type that General Motors built. Swapping it needs only common tools, and the owner's manual covers taking out the old thermostat and fitting the new one. Mercury gives the part a 1 year factory warranty.
Our take
The 140°F rating is the figure to match on the 59078T3, and the cork gasket in the kit means the seal is renewed along with the thermostat. It targets older GM-built MerCruiser inline 4- and 6-cylinder engines, so confirm yours is one.
