ABSTRACT:
An outboard motor includes a fuel supply system which minimizes and curbs fuel spillage when the outboard motor is placed in a non-upright position. The fuel supply system includes an internal fuel tank which communicates with at least one intake passage of an engine of the outboard motor via a fuel vapor discharge line. The discharge line extends between a vapor discharge port on the fuel tank and a vapor suction port on the engine. The ports and the discharge line are arranged within the outboard motor to inhibit significant spillage or drainage of liquid fuel from the fuel tank through the vapor discharge line regardless of the orientation of the outboard motor, such as, for example, when the outboard motor is inverted or is laid over on its side.
