Abstract

An outboard motor is provided with an air duct located within the cavity of a cowl of an outboard motor. The air duct defines a chamber within it in association with first and second openings that allow heated air to flow, through the creation of convection currents, out of the engine compartment under a cowl. This convection flow removes heat from fuel system components and reduces the likelihood that “vapor lock” will occur subsequent to the use of an internal combustion engine that is followed by turning the engine off.
