On 4/13/13 i, indiana conservation officer was dispatched to a boat accident involving personal injury on monroe reservoir east of the cutright ramp. Upon arriving in the area i observed a boat being towed by another boat toward the cutright ramp. I was able to ascertain that the boat being towed was the one involved in the accident and followed them to the ramp. Upon arriving at the ramp i noticed a subject laying on the rear of the boat. The subject was conscious and alert and stated that his lower back was in pain and he could not move his legs. Shortly after our arrival ems arrived on scene and tended to victim. 
   i then spoke with witness who witnessed the accident and also assisted in getting victim out of the water. Witness advised that he saw victim traveling east in the area of hooks point when victim's boat came to a sudden stop and spun around in a circle, throwing victim out of the boat. Witness said that he went over to victim's location and helped get victim back into his boat. Witness then towed victim's boat to the cutright ramp. I asked witness how fast victim was traveling when the boat stopped and he told me that he was not on plane but he was going pretty fast.
   i also spoke with a passenger in victim's boat and asked him what had occurred. He stated that the boat suddenly came to a stop and spun around in a circle. He said that victim was thrown out of the boat and he was thrown over to the driver's side of the boat and landed in the floor. Passenger then used a landing net to reach out to victim and he took hold of the net. Passenger then pulled victim to the rear of the boat and tried to get him into the boat but was unable to. witness then came to passenger's aid and they were able to get victim into the boat. I asked passenger how fast they were traveling and he stated that they were not on plane but they were above idle speed, plowing water. 
   victim was transported to bloomington hospital and passenger refused medical treatment, although he did sustain some scrapes to the right side of his face. Both victim and passenger were wearing life jackets at the time of the accident. 
   victim's boat was taken out of the water and i looked over the motor which was the only part that i found to have sustained damage. The entire lower part of the motor was gone. Due to the damage done it appeared that the lower part of the motor had struck something with a lot of force. Due to my experience patrolling the east end of monroe reservoir, which is an idle zone, victim had to be traveling faster than idle speed for the lower part of the motor to be completely broke off by hitting something submerged in the water.
