RedactedNarrative: Vessel was eastbound at 60 mph. Vessel either hit something or had a outdrive failure that caused one outdrive to become separated from the hull. The vessel then suddenly turned sideways and skipped across the water until it partially flipped causing 4 people to be ejected into the water. The separated outdrive heavily damaged the second outdrive causing the vessel to be powerless. The vessel scooped some water in last flip. The water was pumped out, no water entering the boat from damage. Two people were transported to McLaren Northern Michigan ER by Emmet ambulance, vessel was towed to Petoskey Marine.  A vessel behind the accident vessel assisted with extracting people out of the water.
