Operator and passenger of vessel #1 fell off PWC.  When they climbed back on, the PWC had stalled and they were unable to restart the engine.  A passing boat created a wake and pushed the now drifting PWC into the pier at 2906 South Riverside Drive.  Operator's left hand was crushed between the left handlebar of the PWC and the pier.  Operator transported by family members to hospital for treatment.
