Vessel #1 was traveling westbound on Lake Havasu in the area of Site 5 at 50-60 miles per hour.  Investigation shows that the port side drive gimbal ring failed causing the drive to separate from the transom housing.  The port side drive was pulled into the water which in turn caused the starboard drive to be pulled hard to the port side.  The drives are connected together by a tie rod.  This action caused vessel #1 to turn hard to port.  Vessel #1 then spun around several times ejecting all occupants.
