    • 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.
