ABSTRACT:
This disclosure relates to a small craft equipped with a water jet propulsion system and a thrust-reversing device. The thrust-reversing device is supported for movement up and down between an operating position located directly to the rear of the exhaust port of the jet propulsion system and a retracted position located upwardly from the operating position. The thrust-reversing device includes a U-shaped water guide passage which extends laterally; the left and right ends of the water guide passage are shaped into concave ends which curve forwardly; and the bottom of the hull of the craft includes channels aligned with the curved ends of the water guide passage of the thrust-reversing device when the device is at the operating position.
