PROBLEM TO BE SOLVED: To provide a water jet propulsion boat for preventing the worsening of re-startability of an engine by hardly causing a detecting error or failure in a fuel pressure detecting device. SOLUTION: In a boat body 11 of the water jet propulsion boat 10, a fuel tank 20 is provided via vibration absorbing materials 21a, 21b. A fuel pump part 30 including a fuel pump body 33 is provided in the fuel tank 20, and a fuel pressure sensor 36 is provided in the fuel pump part 30. When a value detected by the fuel pressure sensor 36 is outside a normal value range, an electric control device 40 stops the operation of the fuel pump body 33. Besides, when a turnover sensor 41 detects the overturn of the boat body 11 and the value detected by the fuel pressure sensor 36 is outside the normal value range, the electric control device 40 stops the operation of the fuel pump body 33. A regulator 34 and a filter 35 are provided in the fuel pump part 30. COPYRIGHT: (C)2009,JPO&INPIT
