Abstract
An air aspiration prevention pan adapted to prevent aerated water from entering the intake of a water jet propulsion unit mounted in the hull of a water craft having low or zero dead rise characteristics or in a hull having sponsons or spaced apart skegs. The air aspiration prevention pan comprises sidewalls extending downwardly from the mounting means in a general V-configuration with the apex of the "V" toward the forward end of the hull. A lip extends outwardly from the bottom of the sidewalls and acts with them to confine and guide the aerated water under the hull so as to prevent a substantial portion of the aerated water from entering the intake of the water jet propulsion unit.
