PURPOSE:To prevent deterioration of lubricant by providing a cooling part for cooling an oil passage which couples an oil receiver with a discharge port for lubricant by cooling water fed by a water pump. CONSTITUTION:An oil receiver for receiving lubricant after lubrication of the lubrication-required part of an engine 17 is arranged inside a middle member 16 under a cylinder block 22. Moreover, an oil tank for reservoiring lubricant conveied from the oil receiver is equipped. A pump device 43 is equipped which has an oil sending pumps for transferring lubricant from the oil receiver to an oil tank 42 and a lubricating pump for supplying lubricant to the lubrication- required part of the engine 17. Hereupon, a water pump 71 is equipped, which force-feeds cooling water being taken in from a water intake 72 provided at the periphery of an outboard motor 10. A cooling part is provided, which cools an oil sending passage 66A on the pump side by cooling water sent by the water pump 71. Hereby, the lubricant for lubricating the engine 17 is cooled positively, and the deterioration is prevented. |
