RedactedNarrative: According to the operator, vessel was inbound and traveling through Big Sarasota Pass when the lower outdrive struck an underwater object/ground.  This striking led to the loss of propulsion (starboard) and steering.  The vessel then began to drift and, shortly thereafter, take on water.  This drifting ultimately led to the vessel grounding on a sandbar within Big Sarasota Pass.  To note, the initial event occurred at approximately 1915 hours and a call placed to Sarasota County Dispatch/USCG/FWC at approximately 2240 hours.  All persons on board were removed from the grounded vessel at approximately 2340 hours by the Longboat Key Fire Department.
