RedactedNarrative: On 6/9/2020, operator was operating vessel on the trent river. Operator launched from a private dock at his residence. On board with operator were his wife and sister in law as well as 3 kids being towed on a tube. 
  
  Subject1 and subject2 acted as observers for the kids on the tube. At approximately 5:10 pm, operator was heading eastbound on the trent river back towards his residence. Operator was up on plane and towing the tube when he came up to a left hand bend where a known hazard was located. Operator knew there was a partially submerged tree visible above the water line and maneuvered around the bend as to avoid it. 
  
  As operator cut the corner, his lower unit struck a fully submerged tree, approximately 12"-14" in diameter. The midsection and lower unit from the power unit were completely removed. There were no injuries and no damage to the hull or other parts of the vessel. The vessel remained in the water and came to a complete stop once it lost power. Operator set anchor and waited for a friend to come and tow them out. The tree that operator struck was an unknown hazard and he called uscg to report it. There were no contributing factors to this incident and the tree that was struck was not visible from the water line.
