ABSTRACT:
A fouling removal system for use in a water-jet drive system is described. The fouling removal system includes a cutter arm assembly and an optional cutter stud. The cutter arm assembly includes a pivotable cutting blade located adjacent to the intake grate and arranged to sever any debris, such as seaweed and eel grass, clogging the intake grate. The cutter arm assembly may be tied into existing watercraft hydraulic systems to use a hydraulic cylinder to cause movement of the cutting blade across the surface of the intake grate. The optional cutter stud is located adjacent to the impeller within the water-jet drive system housing. The cutter stud acts to sever debris associated with the impeller blades, which, if left on the blades, would reduce the efficiency of the impeller. The present fouling system is capable of removing debris from the intake grate and impeller of a water-jet drive while a watercraft is stationary or is operating at any speed, including full speed.
