Abstract
A weed grate for a watercraft having a jet propulsion unit. The weed grate includes a plurality of cantilever tines each joined to a pivot rod. The cantilever tines extend across the inlet opening for the jet drive to prevent debris from entering through the water inlet opening. A spring member is mounted between the cantilever tines and a mounting frame such that the spring member provides an outward rotational bias force against the rotatable cantilever tines. During operation of the watercraft, if a mass of weeds becomes clogged in the cantilever tines, the upward and inward suction force of the jet drives causes the cantilever tines to rotate upward against the rotational bias force and allow the weeds to be ingested by the jet drive.
