PROBLEM TO BE SOLVED: To provide a ship propulsion machine which enables an amount of a discharged coolant to increase while maintaining durability of a coolant pump.SOLUTION: An outboard engine (a ship propulsion machine) includes: an engine; a drive shaft 2 which is connected with the engine so as to transmit power to the engine; a first coolant pump 6 which is driven by a driving force of the drive shaft 2 and sends a coolant for cooling the engine; a coolant passage 8 which supplies the coolant sent by the first coolant pump 6 to the engine; and a second coolant pump 7 which is disposed in a water passage at the upstream of a suction port 64 of the first coolant pump 6 and compresses the coolant supplied to the suction port 64 of the first coolant pump 6.

    【課題】冷却水ポンプの耐久性を維持しつつ、冷却水の吐出量を増加させることが可能な船舶推進機を提供する。【解決手段】この船外機(船舶推進機)は、エンジンと、エンジンに動力伝達可能に連結されたドライブシャフト2と、ドライブシャフト2の駆動力により駆動され、エンジンを冷却するための冷却水を送る第1冷却水ポンプ6と、第1冷却水ポンプ6により送られる冷却水をエンジンに供給する冷却水通路8と、第1冷却水ポンプ6の吸込み口64上流の水路に配置され、第1冷却水ポンプ6の吸込み口64に供給される冷却水を加圧する第2冷却水ポンプ7とを備える。【選択図】図4
