A water jet pump is constructed by attaching an impeller to the lower end of an impeller shaft that extends rearward from the transom of the hull and is supported approximately vertically within a spirally formed casing. A water jet propulsion device characterized in that the upper end of an impeller shaft of a water jet pump is connected to the output shaft of an engine disposed above the water jet pump via a mounting seat.
