RedactedNarrative: Unit 1 turned around to retrieve a float that had blown out of the boat while underway. Once they got close, the operator stood on the swim deck at the stern of Unit 1, believing the vessel was in neutral. Due to wake, moisture on the swim deck, or loss of balance the operator slipped into the water. The operator of Unit 1 was immediately struck and sucked in by the propeller. The propeller ripped all of the operators clothing off while also causing deep lacerations to his face, right flank, and right shoulder. Passengers pulled the victim/operator back into the boat after he resurfaced and contacted emergency personnel. The victim was flown to Greenville Memorial Hospital by LifeNet Medivac. The boat throttle control was in reverse when investigative personnel located the vessel.
