RedactedNarrative: Operator was transitioning through Cedar Island Bay on the Eastern Shore when he struck an unidentified submerged object.  The object struck his motor pulling it to the side and ejecting him.  The boat continued in a circle and came back toward him.  At this point he curled up and the prop struck his legs, primarily on the right side.  He had his PFD and had a cell phone so he called for help and swam to shore.  EMS arrived and transported him to Riverside Shore Memorial Hospital and a family member recovered the vessel.
