Specifications

Opens at
140°F

Mercury thermostat kit 59078T3 contains a 140°F thermostat and a cork gasket in a 2-piece kit. It is meant for older General Motors based MerCruiser engines, in-line 4-cylinder and 6-cylinder. The maker calls it easy to replace with common tools, and points to the owner's manual for removing the old thermostat and installing the new one.

Our take

Rated 140°F, the 59078T3 comes as a 2-piece kit with a cork gasket, so the gasket is handled in the same job as the thermostat. It is meant for older GM-based MerCruiser inline 4 and 6 cylinder engines.
