ABSTRACT:
An operator-actuated inlet grate clean-out mechanism which can be actuated by pushing and pulling a cable or rotating a shaft from the driver's seat of a boat. A weed wiper which is arranged to push weeds off of a pivotable cantilever-tine inlet grate as the wiper travels along the tines and toward the aft tips of the tines. As the wiper sweeps along the inlet grate tines, it bears against the inlet grate and causes the grate to swing downward to a position where the aft tips of the cantilever tines are spaced from the pump jet housing. Because the weeds wrap and ball around the inlet grate, they also slide off easily when pushed or dragged by the sweeping wiper bar.
