Ventilation
Boats built prior to Aug. 1, 1980: At least two ventilator ducts fitted with cowls or their equivalent, for the purpose of properly and efficiently ventilating the bilges of every closed engine and fuel-tank compartment on boats constructed or decked over after April 25, 1940, using gasoline as fuel or other fuels having a flash point of 110 degrees or less.
Boats built after Aug. 1, 1980: At least two ventilator ducts for the purpose of efficiently ventilating every closed compartment that contains a gasoline engine and every closed compartment containing a gasoline tank, except for those having permanently installed tanks which vent outside the boat and contain no unprotected electrical devices. Also, engine compartments containing a gasoline engine having a cranking motor must contain power operated exhaust blowers which can be controlled from the instrument panel.
