ABSTRACT:
A marine jet propulsion water inlet system having panels extending from the inlet opening at the bottom of a watercraft downstream, upward and rearwardly, in the water channel. The panels extend to the upper wall of the water channel or are integral with the upper wall. In this way, aquatic vegetation and debris will not have any surface to wrap around. This results in greatly reduced clogging of the water channel. The panels are also integral with downwardly extending fins which are beneath the bottom of the watercraft and which have edges that are also designed to direct vegetation and debris along the fin and pass the craft to reduce or eliminate the adhesion of vegetation and debris.
