Synopsis of Officer Narrative, narrative larger than space will allow.(complete narrative available upon request)
Dispatch notified of a man stuck in the propeller of a vessel, still underwater around 1603 near Sand King on Lake Powell Utah. I arrived on scene at about 1612 and saw multiple people running around screaming "help he is unconscious" I notified to launch classic when I observed the victim was being pulled to the shoreline and I could see definite lacerations on the lower extremities. I took over my medical bag/backboard and we loaded him on the board and got him out of the water. Tourniquets were applied to both legs just beneath the groin by a couple of bystanders. Classic Lifeguard arrived shortly after NPS and they took over care of the patient from there. We were able to get the victim loaded and sent to Flagstaff by Classic Lifeguard.
It is of my opinion and still under investigation that the cause of this accident was preventable. It is believed from witness statements given on scene and written, and under investigation that Victim was swimming toward the vessel, the vessel engines were started and put into gear by Operator. It is of my opinion due to the damage caused that the vessel was in reverse at the time of the accident. This case is still under investigation. NPS rangers had the vessel pulled from the water and we will be testing it to see if it starts in gear or if it has to be in natural to start the engines, we will be looking for any mechanical failure that may have played a part in the accident, which is not believed to be the case at this time.

The operator of the vessel showed very very distinct nystagmus in both eyes and blew a reading of .178. Operator did give a reading in the intoxilyzer at 1945 UT TIME to which he gave a reading of .124 I had him charged with 41-6a-503(2a) Driving under the influence with inflicted serious bodily injury upon another. At that time it was unclear if the victim was alive or not.  NPS rangers notified me that alcohol probably had a part in the accident because the odor of alcoholic beverages was very present on most of the persons we were told were in/on or around the boat during the time of the accident.

Victim was still alive but in critical condition and not breathing on his own.  He later told me that he had blood lose between 75-85% of his blood and that as of (then) they had not amputated either of his legs, but it was still a possibility that he would loose one of them due to severe infection.

Update - (1846 UT time) I just got back from the boat repair shop with NPS ranger. We (along with a employee down at the repair shop) tested the boat to see if it would start in gear; it did not and functioned properly. The boat has to be in neutral to start the boat, and the propeller does not move in neutral. The only visible damage was to one of the propeller fins, it was missing a chunk off of it. We were told it had to be fresh because boat rentals will not send out a boat missing part of the prop. I took pictures of the boat I will attach. We also checked the ladder on the back of the boat and it functioned properly. I was told that if the boat were in reverse it would have some suction power with the prop. But the employee didn't know any numbers or how much, he could only tell me it would have suction power.
