大きくなって推進効率が低下するという欠点がある。(Prior Art) In recent years, small jet propulsion boats that are engines and that slide on water have come into wide use. This small jet propulsion boat often slides along the waves, so it may become invisible to other ships when it is located in the waves during the run, and it collides with other ships due to high-speed gliding. There is a fear of. Vehicles with this kind of problem include cars (buggy) that drive in undulating deserts. In this car, a flag is set to indicate the existence of one's own, which prevents collisions with other cars. I have to. It is possible to attach this flag to the small jet propulsion watercraft, but if the flag is attached, the structure such as the attachment of the pole of the flag becomes large, and there is a drawback that the resistance due to it becomes large and the propulsion efficiency decreases.

船の存在を瞬時に知らせることができる。As described above, since the water flow of the propulsion unit of the jet propulsion boat is used to eject the water, the water is ejected upward through the water ejection passage during traveling. Moreover, since the jet flow from the propulsion unit is used, water can be jetted instantly by increasing the rotation of the engine even when the propulsion boat is at a low speed or in a stopped state. Therefore, even when the propulsion boat is located at the bottom of the wave, the jet flow can instantly inform other ships of the existence of the own ship.

A propeller is attached to a tip end portion of a propeller shaft that is rotated by the engine, and the propeller is configured to rotate in a water channel arranged below the rear end of the seat 5 on the lower side. The nozzle 7 is provided at the tip of the water channel so that the direction can be changed.
Is attached, and the water is sucked from the suction port at the bottom of the ship by the rotation of the propeller to be jetted from the nozzle 7 in a predetermined direction, whereby the ship is turned and propelled.
