RedactedNarrative: On 10/15/2022, at approximately 7:35 AM a 2015 Phoenix bass boat, driven by O1, was traveling Southbound on the TN River near mile marker 144. The damage to the vessel and statements collected all corroborate that his boat collided with a submerged object. This resulted in the lower unit of the outboard being torn off. Not having a lower unit resulted in a loss of steering, causing the vessel to rotate violently. He attempted to regain control of the vessel but failed. He was ejected from the starboard side of the vessel. Once the vessel had come to a stop, occupant (passenger) made his way to the trolling motor. Occupant navigated the vessel toward operator and assisted him back into the boat. Nearby fisherman stopped to offer assistance and called for help.
