RedactedNarrative: Operator A was fishing out of Vessel A on the lake, near the shore.  He was operating at a slow speed, standing on the metal bench seat nearest to the transom, with his right foot on the seat and his left foot on the outboard throttle.  He lost his balance and his left foot rolled the throttle, increasing the speed of the boat and causing him to fall out.  Operator A wasn't wearing a PFD.  The boat circled and the port side of the boat struck him on the right side of the face and the propeller caught his down vest, causing the motor to stall and he sustained a laceration to his chest.  A group of nearby fishermen in a boat that witnessed the event came to help Operator A with getting his clothing untangled and pulled him aboard their boat and transported him to shore, where they were met by an ambulance.
