On 8/6/2011 i was dispatched to horse mesa dam reference a boat accident with injuries. While enroute i was flaged down by another boater who said he had the 2 injured parties on board his boat and he brought them to the aids station. After getting them inside they were assessed and secured to backboards awaiting arrival of helicopters to take them to the hospital. The operator had sustained an injury to his left rear scull and had an obvious bump. When asked he could not remember any events that happened. I was advised later that he had a concussion and alcohol tests were negative. The passenger had sustained a full thickness laceration to the right calf area of her leg, but was non life threatening. I located the watercraft as it had been removed from the water be fellow boaters. Upon checking the vessel it was pointed out to me by one of the subjects who took the boat out of the water that the possible cause for the boat to flip was that the prop shaft had slid back into the rubber causing it to turn to the right in a locked position. This with the speed would cause by what the witnesses said would cause the boat to pitch to the right and downward due to the chop in the water at that time. This information was consistent with the damage observed by the propeller and rudder. The only other visible damage that i could see was the forward velocity stack was forcibly removed from the carburator. No other damage was observed to the hull. The boat was secured at the 3 lane boat ramp and would be returned to the owner who was on scene as well. Nothing further.
