Abstract
A water jet apparatus has a reverse gate which allows a boat or other marine craft to be steered in reverse in the same manner as an automobile. The reverse gate accomplishes this by reversing the flow exiting the steering nozzle. When the steering nozzle is positioned to the left, causing the rearward exit flow to be directed to the left side of a midplane of the water jet apparatus, the reverse gate redirects that leftward and rearward flow so that it flows rightward and forward. Conversely, when the steering nozzle is positioned to the right, causing the rearward exit flow to be directed to the right side of the midplane, the reverse gate redirects that rightward and rearward flow so that it flows leftward and forward.
