Marine propulsion device |
摘要 |
A marine propulsion device includes an engine, a driving shaft coupled to the engine and configured to transmit power, a first cooling water pump configured to be driven by the driving force of the driving shaft and to pump cooling water to cool the engine, a cooling water path configured to supply the cooling water sent by the first cooling water pump to the engine, and a pressurization mechanism arranged in a water passage upstream of a suction port of the first cooling water pump and configured to apply pressure to the cooling water supplied to the suction port of the first cooling water pump. |

1. A marine propulsion device comprising:
an engine; a driving shaft coupled to the engine and configured to transmit power; a first cooling water pump configured to be driven by a driving force of the driving shaft and to pump cooling water to cool the engine; a cooling water path configured to supply the cooling water pumped by the first cooling water pump to the engine; and a pressurization mechanism arranged in a water passage upstream of a suction port of the first cooling water pump and configured to apply pressure to the cooling water supplied to the suction port of the first cooling water pump; wherein the pressurization mechanism includes a rotating body configured to be driven by the driving force of the driving shaft. |
