Abstract
An outboard motor is provided with a water-cooled engine having a crank shaft arranged substantially in a vertical direction and a fuel is supplied to the engine through a fuel injector after temporarily introducing the fuel to a vapor separator. A high pressure fuel pump is arranged in the vapor separator so as to feed the fuel under pressure to the fuel injector, a pressure regulator is arranged in the vapor separator so as to reduce a pressure of a return fuel, a fuel cooler having a fuel passage and a cooling water passage arranged side by side in parallel to each other is arranged on an upstream side of the pressure regulator, and cooling water for cooling the engine is introduced to the cooling water passage so as to cool the fuel in the fuel passage.
