RedactedNarrative: According to family members, the owner/operator launched his 16' aluminum jet boat at martin's landing in the snake river. He proceeded upstream attempting to warm up the boat.  For unknown reasons, the boat accelerated and turned sharply causing victim to be ejected from the vessel.  Family members saw victim floating downstream for approximately 200 yards and then lost sight of him.  The vessel continued to turn in tight circles in the river, unoccupied.  The vessel eventually collided into some trees on the bank approximately 2 miles downstream from the original site.  Upon my arrival, the boat was in the trees, with its engine still running and its bow was up out of the water.  It was determined at that time that the boat was in a location that made it hazardous or unsafe to attempt to recover it.  After running for several hours, the engine finally quit running.   The bow was extremely elevated and the port stern was just inches out of the water.  The vessel took on water and capsized, then floated downstream and was located again. 
  
  The initial boat accident was at approximately  43.807286, -117.027823.
  The victim was located approximately 54 hours after the initial accident was reported.  He was located  at    43.839912, -117.014114.
