RedactedNarrative: On Jul 25, 2015 at approximately 9:40 PM, Subject undocked from slip in Burnham Harbor, Chicago. He was heading to Lake Michigan for recreational cruising. As Operator1 was about to make the right hand turn out of the dock area he pulled back on the dual engine throttle to slow the vessel down but only the starboard side engine stopped, the port side engine kept throttling forward. 
  
  Operator1 pulled back hard again on both throttles but they were already all the way down. Operator1''s boat pulled hard starboard and his bow anchor impacted V2 bow, which was in is slip, tied down and at rest. Operator1''s boat finally came to a stop due to the impact, the stuck engine finally cut off. Later inspection discovered a broken throttle cable which kept the starboard engine at idle.  Both boat owners know each other, they exchanged insurance information and called the IDNR office in Bartlett.
  CPO receive the message and met with both parties on July 27, 2015 in Burnham Harbor
