To provide a ship propulsion machine capable of improving sailing performance by downsizing or slimming a gear case, or capable of making it easy to put on/take off the gear case to the ship propulsion machine.SOLUTION: In an outboard engine 11 as a ship propulsion machine, an electric motor 12 as a power source, a tank 32 which stores cooling water for cooling the electric motor 12 and so on, and a pump 34 which circulates the cooling water are installed on the top of the outboard engine 11, a gear case 22 with a gear mechanism 21 housed inside and with rotatably supported propeller 20 is installed at the bottom of the outboard engine 11, and a heatsink 51 which cools the cooling water is installed at a position lower than the electric motor 12 and higher than the gear case 22.SELECTED DRAWING: Figure 1

    【課題】ギヤケースを小型化またはスリム化して航走性能を向上させ、または、船舶推進機に対するギヤケースの着脱を容易にする。【解決手段】船舶推進機としての船外機11において、動力源としての電動モータ12、電動モータ12等を冷却するための冷却水を貯えるタンク32および冷却水を循環させるポンプ34は船外機11の上部に設けられ、ギヤ機構21が収容され、かつプロペラ20が回転可能に支持されたギヤケース22は船外機11の下部に設けられ、冷却水を冷却するヒートシンク51は、電動モータ12よりも低く、かつギヤケース22よりも高い位置に設けられている。【選択図】図1
