The operator indicated that he had run this area many times around 6,000 to 16,000+ mostly between 7,000 and 9,000.  He said he had never had any problem before, but this run went wrong FAST.  Water was 8,800 in the AM when they checked.  Two other boats were just below the rapids and said they had problems climbing it.  There were going to watch them to see what they did.  So they followed up.  The operator indicated they he took it easy going up looked it over saw nothing different than a half a week ago.  Pulled onto the top of the wave, started to slide over to the right, just like I always do, and all at once the water fell out from under the boat.  Dropping the nose when that happened, the operator pushed the stick steering to the far right turn the boat and heading to the road side bank.  The operator pulled the steering to the left and as he did that they started to hit the rocks on the bank.  Once everyone was safe on the bank, they started to remove everything they could from the boat onto the bank.  They looked at the damage, it appeared not to have any holes in the boat but a compression dent on the starboard side.  When they stopped the motor was running, then they shut it off, the pump appeared to be okay also.  But water was running over the back side of the boat, very little in the beginning, but later the water running in the boat pushed the boat on the side and then more water was coming in.  They found no holes or anything else once the water was removed, checked the oil, no water was visable.  Started the motor and pushed and pulled the boat off the rocks this took about 3 hours.  Drove the boat up thru the rest of the rapid and then back down.  The motor started to run rough. After cleaning the filters, they drove the boat back to the ramp and loaded it on the trailer.
