Operator was driving his boat, IA registration 9617AP with two people as passengers on Saylorville Lake by Sand Piper boat ramp.  As they were boating, Operator took a sharp turn which resulted in ejecting Operator and Occupant1 out of the boat.  Occupant2 remained in the boat where he slowed down the throttle of the boat, was unable to shut the motor off so he steered the boat so it would go in circles and jumped out to help his sister.  During that time Operator drowned in the water.  Another person, in his sailboat, saw the two kids in the water and sailed over to rescue the kids.  Good samaritan also turned Operator's boat off and called 911.  The Army Corps of Engineers and Polk City Fire & Rescue responded to the scene, found Operator's body and attempted to resuscitate him, but were unsuccessful.  Operator was found without a PFD, both kids were wearing PFDs prior to the accident.
