The AeroTherm electric engine heater from Sporty's supplies 190 F air to the engine compartment, evenly and consistently heating all parts of the engine with no bulky propane tank to haul around or refill. With 500-, 1,000-, and 1,500-watt settings and a thermostat, the heater can remain plugged in all winter long maintaining an optimum, preselected temperature for pennies a day. Used as a preheater, it will warm the engine enough for starting in about an hour, or completely warm the engine in three hours with an outside temperature of 0 F. Included are two hoses, a stand, carrying case, a nylon suspension band for hanging the unit from the prop, and four sponges to seal the engine intakes for increasingly warm air.
