The operator of a PWC told deputies that she was operating her stand-up PWC, with her son seated in front of her.  Once they made it past their dock, the son stood up and accidently grabbed the throttle.  The sudden acceleration threw the mother off the back, but she was still able to hold on to one side of the handlebars causing the PWC to turn and go in circles.  The mother wasn't able to hold on any longer, she let go and the PWC with the son on board crashed into the neighbors dock.  The impact with the dock caused the son to propel forward into the PWC.  Then the son was ejected off the PWC, landing in the water, near the shore.  The son was transported to Kootenai Medical Center with head injuries and minor cuts and scrapes.
