RedactedNarrative: On 09/02/2017, a rented Cobalt was underway by operator when the motor sputtered and stopped working.  The operator saw that water was coming into the boat from the stern, and turned on the bilge pump and visibly saw the bilge pump flooding out water.  The vessel began rapidly taking on water and the operator called the rental company, Just Add Water Sports (JAWS) of Coeur d'Alene, Idaho.  The rental company advised that the passengers put on PFDs and to get to the bow of the boat and that they would be on their way to make contact.  The vessel within minutes, rapidly took on water and sank in a few minutes.  The former operator and passengers were then rescued by another friendly vessel who saw the bow of the rental boat sink beneath the water surface.
