ABSTRACT:
An outboard motor comprises an engine of vertical type in which a crank shaft is disposed vertically in an installed state of the engine, an engine holder supporting the engine, an oil pan which is disposed below the engine through the engine holder and in which an oil is accumulated, and a lubricating device for lubricating the oil from the oil pan to an inside of the engine. The lubricating device comprises an oil pump mounted to a lower side portion of the engine holder and adapted to suck the oil accumulated in the oil pan, an oil suction passage and an oil discharge passage. The oil suction passage and oil discharge passage extend in parallel to each other from the oil pump and are formed integrally with an inside portion of the engine holder.
