RedactedNarrative: On August 14th, 2016, I, Game Warden#1, was on duty at Lake Mead National Recreation Area, I was in the 704 office processing paperwork. The National Park Service received a call of a vessel in distress, taking on water with seven individuals on board. The vessel location was adjacent to Painters Cove. I responded from the 704 office and launched my vessel from government dock.
  
  As I was approaching the area, an individual on a jet ski waived me down. He informed me that the vessel had been towed to shore and was now beached on the north side of Kingman Wash. The jet ski led me into the vessel, when I had visual I waved him off. 
  
  I arrived on scene at 13:47, I found the vessel beached and tied off. The vessel stern was sitting noticeably low in the water, seven individuals were on shore, 4 men 3 women. There were no reported injuries. The vessel bilge pump was running consistently while I was on scene.
  
  The owner of the vessel, Owner#1 explained to me that they had been motoring on the lake, when he stopped the vessel for a moment it stalled and would not restart. Owner#1 noticed that the vessel's stern was sitting lower in the water than it normally does; this was evident to Owner#1 due to the swim deck being slightly under water. Owner#1 opened the engine cover and noticed water rushing in. Again Owner#1 tried to start the vessel but it would not start. Owner#1 was able to phone the National Park Service notifying them of their situation.
  
  A passing Good Samaritan vessel the Jet Ski was able to tow the boat to Kingman Wash where I found it.
  
  Owner#1 stated that he did not know what happened, he stated that he had not taken the boat out in about two months. All seven individuals had donned their life jackets. On scene I confirmed that the vessel was equipped with the proper safety equipment. I asked Owner#1 if he had consumed any alcohol and he said that he had not, Owner#1 said they had a cooler with water and food. I confirmed that there was no alcohol in the cooler.
  
  Shortly after my arrival, a NPS vessel arrived to assist. NPS transported the 3 women to the Las Vegas Boat Harbor due to the fact that it was very hot.
  
  I discussed vessel assist with Owner#1 and he asked me to call and initiate them to the scene. I spoke to Rep#1 at approximately 14:20 hrs, explained the situation as well as texted him the GPS co-ordinates and a picture of the vessel.
  
  There was a mechanical failure with the vessel which allowed the water to enter the hull of the ship. 
  On 8/17/2016 I spoke to Rep#2 the owner of the Vessel Assist firm. He informed me that the boat was hauled to his shop in Mohave Valley; AZ. Rep#2 explained to me that none of the stern drive housing components had failed. Rep#2 stated that the through hull deck drain one way scuppers had failed to prevent water from rushing in through the hull. Rep#2 explained that once they were able to pump the boat out and inspect the out drive there were no noticeable defects, but water was entering the hull from the deck drains when stationary. When the vessel is running and on plane water will not enter, but when stationary the cracked one way scuppers failed to operate properly.
