ABSTRACT:
A propeller system for an outboard motor, comprising a revised propeller, a symmetrical or Kort-type accelerating nozzle, and re-routed exhaust passages, is described. This system permits modification of a standard outboard motor intended for use with a planing type hull to make it applicable to a sailboat immersion type hull. The motor fuel consumption may also be improved.
