摘要： Disclosed is a personal watercraft having a water cooling system of an engine, which allows inside of a cooling water passage of an engine or a water passage connected to the cooling water passage to be sufficiently cleaned and a clogged water-supply hole in an expansion chamber to be easily inspected or cleaned. The personal watercraft 1 comprises a first water passage 50 from a water jet pump 7 to a cooling water passage of an engine 4. Water is forcibly sent by the water jet pump 7 and led to the cooling water passage through the first water passage 50. The water flows through the cooling water passage while exchanging heat, and the resulting water is discharged outside the watercraft. The personal watercraft 1 further comprises a second water passage 53 opened in a surface of a body of the watercraft and communicating with the first water passage 50, and an opening/closing means 54 for opening/closing the second water passage 53.

摘要： Disclosed is a personal watercraft comprising an engine capable of achieving a high power without increasing the diameter of an output shaft where a crankshaft-side sprocket is attached, and thus without increasing the diameter of the sprocket. The engine is configured such that an extended shaft that is separable from the crankshaft and has a diameter smaller than that of the crankshaft is connected to one end portion of the crankshaft so as to be coaxial with the crankshaft, and a sprocket is provided on the extended shaft. With such a structure, by forming the extended shaft of a material having relatively high strength, the diameter of the extended shaft can be made smaller than that of the crankshaft, and hence, the diameter of the sprocket provided on the extended shaft can be reduced. Since the diameter of a camshaft-side sprocket can be reduced, the size of the entire engine can be reduced.
摘要翻译：公开了一种个人船舶，其包括能够实现高功率而不增加安装曲轴侧链轮的输出轴的直径的发动机，因此不增加链轮的直径。发动机构造成使得与曲轴分离并且具有小于曲轴的直径的延伸轴连接到曲轴的一个端部以与曲轴同轴，并且链轮设置在延长轴。通过这样的结构，通过形成具有相对高强度的材料的延伸轴，延伸轴的直径可以比曲轴的直径小，因此可以减小设置在延伸轴上的链轮的直径。由于可以减小凸轮轴侧链轮的直径，所以可以减小整个发动机的尺寸。
