ABSTRACT:
A trim tab is provided in the internal portion of a nozzle of a jet propulsion system. The trim tab can be rotating about an axis to expose a surface of the trim tab to the jet stream of water passing through the nozzles of the jet propulsion system. The exposure of one of the trim tab surfaces creates a thrust vector in either the port or starboard direction which creates a corrective thrust, in a desired direction, which overcomes any manufacturing misalignments.
