Abstract
An outboard motor includes an engine holder, an engine which is disposed above the engine holder in a state of the outboard motor mounted to a hull and in which a crankshaft extends substantially perpendicularly, and an oil pan disposed below the engine holder. A drive shaft housing is disposed below the oil pan and is formed with an exhaust chamber and a water pump is driven by the drive shaft so as to pump up a cooling water. A cooling water passage is formed in the oil pan and the drive shaft housing to guide the cooling water pumped up by the water pump to the engine. A relief valve is disposed on the way of the cooling water passage so as to discharge the cooling water into the exhaust chamber.
