RedactedNarrative: At approximately 9:00 pm V1 was drifting & victim jumped off to go swimming. Being a new boat, the owner of V1 didn't turn off the motor yet left it in neutral as the boat drifted, because he doesn't turn it off after dark. Operator/Owner had moved behind the operators seat and then Occupant moved over by the operators seat.  When she did this, she leaned up against the shifter and bumped it into reverse.  The kill switch was pushed immediately but the victim had already been hit by the prop.  The victim was not wearing a life jacket.
