Abstract
A method for inverting a rotation of an impeller driven by a motor of a watercraft is disclosed. In response to sensing that the motor is stopped, a direct linkage is disconnected between the motor and the impeller and a reverse connection is established between the motor and the impeller. The motor is started after sensing that the reverse connection is established. A watercraft propulsion system having an electronic control unit configured to perform the method and a watercraft including the watercraft propulsion system are also disclosed. Reverse operation of the impeller is useful in removing debris from the jet propulsion system.
