A 55-year-old man was found dead floating by his boat in the Great South Bay on Thursday morning, Suffolk County police said.
Marine Bureau officers found Steven Maichen, of East Patchogue, floating by the boat in Bellport Bay about ¾ of a mile southeast of Bellport Dock and Marina at 11:15 a.m.
Maichen appeared to have had engine trouble because the cowling of his engine was removed and inside the boat.
Officers removed Maichen from the water and took him to the dock, where he was pronounced dead.
Maichen was taken to the Suffolk County Medical Examiner’s Office, where an autopsy will be performed.
Homicide Squad detectives say the death appears to be non-criminal but they are continuing the investigation.
