Abstract:

To provide a water jet propulsion boat capable of withdrawing a reverse gate to an advance position when a failure occurs.

A water jet propulsion boat includes: a jet pump; a reverse gate 11; a reverse gate moving mechanism 25, and an ECU 26. The reverse gate moving mechanism 25 includes: an electric motor 27 which generates power for moving the reverse gate 11 between a reverse position and an advance position; and a transmission mechanism 28 which forms a transmission passage for connecting the electric motor 27 and the reverse gate 11 and transmits the power by the transmission passage. The ECU 26 monitors a failure of the reverse gate moving mechanism 25. The ECU 26 withdraws the reverse gate 11 to the advance position when a failure occurs in the reverse gate moving mechanism 25.
