RedactedNarrative: Single vessel, operator is the injured party. Occurred ocean side of Duck Key, Florida. 
  
  Operator stated his injuries included 8 inch long by 14-centimeter-deep laceration to the outside of his left thigh. A small laceration to both left and right heel. Operator stated the vessels’ engines were left on because of a battery issue; he was concerned the vessel would not restart if shut off. 
  
  He believes the starboard throttle was either accidentally left in gear by himself or possibly bumped due to the rough sea conditions and occupants moving around the helm of the center console. Operator stated he typically uses reverse to set the anchor but could not recall if he did this so upon setting anchor the accident location. Operator stated he has well over 100 hours of operator experience on the vessel, FL3610RZ, and has been operating motor vessels since he got his first boat at 10 years old. 
  
  Based on evidence and witness statements I offer this conclusion:
  
  Operator, the injured party, was the last person to operate the vessel at the time of the accident. Operator anchored the vessel at their intended dive spot and intentionally left the engines running when he left the helm to enter the water. 	It is unclear if Operator unintentionally left starboard engine in gear, or the shifter was bumped from neutral into gear when he left the helm. The three other occupants were moving around the center console at the time and the waves were approximately 2-4 feet. 
  
  Subject1 lowered the starboard trim tab for Operator to use as a step to enter/exit the water. Operator entered the water at the transom on the starboard side of the vessel. The propeller then caused a laceration to the outside of Operator’s left thigh, left and right heel of his foot. The engines were then turned off.  Two others got Operator back in the vessel at the transom on the port side of the vessel.
  
  Operator received an approximately 8 inch by 14cm deep laceration to the outside of the left thigh. This laceration severed his femoral artery causing Operator to go into shock. Operator also received a small laceration to the heel of both of his feet. Subject underwent emergency surgery for the laceration to the thigh and stitches for the lacerations on his feet.
