RedactedNarrative: On 7/3/21 at approximately 12:35pm, Operator and Passenger were exiting the Lithia Marina Cove no wake area in a 20'' Shoal Runner 2056 watercraft with MO 8798 EX registration.  After passing the no wake buoy Operator attempted to accelerate the boat to get on plane.  At the same time a wave rolled over the back of the boat causing water to enter the in-board engine compartment swamping the engine.  The engine began to cut out from the swamping.  Operator attempted to turn around and head back to the marina when the boat began to sink.  A nearby boat picked them up and brought them to the Lithia Marina.  The operator was given instructions on how and when to complete the BAR. The Shelby County Dive Team retrieved the boat at 8:30pm and returned it to the owner.
