In 07/28/10 in the icw located on the isle of palms the victim of unit 1 was originally operating unit 1. Victim then asked a 16 year old female passenger, knowing she had minimal experience operating a vessel, to operate unit 1 so that he could wake board. Once in the water victim told Operator to "gun it" referring to the throttle of unit 1. Once she pushed the throttle down unit 1 did three 360 degree rotations to the left in the water, running over victim two times hitting him with the motor's prop because the steering of unit 1 was turned all the way to the left when Operator engaged the throttle the pressure  and torque of the motor trying to come to full speed while turning so tightly caused Operator to be unable to turn the steering wheel of unit 1 to avoid hitting victim. She attempted to straighten the steering but she never attempted to pull the throttle back to slow down unit 1, nor did she attempt to turn unit 1 off. only until unit 1 was finally able to get on plane, was Operator able to straighten the steering. Victim was picked up by a concerned citizen and brought to the iop marina where he was treated by the iop fire department first responders and was transported to musc with severe leg trauma. The owner of unit 1 and the victims father victim stated that he replaced the steering of unit 1approximately 30 days prior to the incident. However, upon checking the steering this reporting officer determined it to be in good working condition. Operator was charged with negligent boat operation  sc50-21-110 citation #748420 and sat before a judge on september 7, 2010 at 1000.
