PROBLEM TO BE SOLVED: To promptly discharge cooling water remaining inside a water jacket of a water-cooled engine after the usage of an outboard motor.SOLUTION: An outboard motor 1 has a water jacket 45 provided on a water-cooled engine; a first path 41 which communicates a downstream side end portion of a flow of cooling water of the water jacket 45 and the outside air; and a thermo valve provided between the downstream side end portion of the flow of the cooling water of the water jacket 45 and an upstream side end portion of a flow of the cooling water of the first path 41. The outboard motor 1 further has a second path 42 which communicates the upstream side of the flow of the cooling water of the thermo valve and the outside air; and a second valve 62 which opens/closes a second passage.SELECTED DRAWING: Figure 3

    【課題】船外機の使用後において、水冷エンジンのウォータージャケットの内部に残留する冷却水を速やかに排出できるようにする。【解決手段】船外機1は、水冷エンジンに設けられたウォータージャケット45と、ウォータージャケット45の冷却水の流れの下流側端部と外気とを連通する第1の経路41と、ウォータージャケット45の冷却水の流れの下流側端部と第1の経路41の冷却水の流れの上流側端部との間に設けられるサーモ弁とを有し、さらに、サーモ弁の冷却水の流れの上流側と外気とを連通する第2の経路42と、第2の通路を開閉する第2の弁62と有する。【選択図】図3
