ABSTRACT:
A carburetor anti-icing apparatus and method for a marine drive is provided for heating a carburetor to a temperature above that at which ice may form in the idle and progression circuits of the carburetor. Several heaters, heat sources, and methods are disclosed for heating the carburetor. In one embodiment an electrical heating element is mounted to the carburetor body near the fuel orifices which make up the idle and progression circuits. In another embodiment, engine cooling water is circulated through a heater housing mounted to the carburetor body. In yet a further embodiment, engine exhaust from the marine drive is conveyed through the heater housing mounted to the carburetor body. A thermally conductive gasket is used to improve heat transfer. The carburetor anti-icing apparatus and method also improves low speed running performance due to the improved fuel vaporization resulting from the increased temperature in the progression circuit.
