A teenage boater was hospitalized Sunday night after he was struck and seriously injured by his own propeller when his boat hit a wave in the Long Island Sound and he was thrown overboard, police said.
The identity of the 18-year-old was not released by Suffolk County police.
Police said the teen was transported to Stony Brook University Hospital after the accident, which was reported at 6:14 p.m. Sunday.
The teen's condition was not immediately known Monday.
Police said he seriously injured his arm. The extent of that injury was not clear.
The teen and another 18-year-old were fishing in the Sound off Mount Sinai when their 17-foot Grady-White struck a wave -- and the boat operator was tossed overboard, police said.
He was then struck by his own propeller, police said.
Police said the teen's friend managed to get the victim aboard the boat, then piloted the craft into Mount Sinai Harbor, where he called for help.
The investigation into the accident is continuing.
