      Johnson Outboard Thermostats

      The boat thermostat is an often underappreciated component of every craft. This mechanism regulates engine temperature and ensures optimal performance. Boat engines run at max performance which can generate a lot of heat. Should the engine begin to overheat, thermostats provide the operator the first line of defense in preventing an expensive repair or possible replacement. In addition, the thermostat other assignment is to control emission levels so your boat stays regulation-compliant.
