ABSTRACT:
A cutting system for fouling removal systems used in water-jet drive systems is described. The cutting system includes an actuation system for facilitating movement of a cutting blade that resides outside of the water flow area for the intake of the jet drive system. The cutting system also includes one or more guide tines to restrict movement of the cutting blade away from the surface of the grate. An optional cutter stud is formed as a single structure including two members forming a single angle, one member for mounting and the other for cutting. The single-angled configuration maximizes cutting efficiency while minimizing disruption of water flow to the propulsion system.
