RedactedNarrative: On 08-05-14, Operator1 barrowed Vessel 1 from his father and launched it at Eden Pines boat ramp. He put the vessel’s shift control in gear and it idled down the canal for approximately 80 yards. He applied more gas to the vessel and then attempted to reduce speed with the shift controls. Operator1 pulled back on the shift controls but the vessel increased in speed due to the throttle control on the engine not working properly. Due to the throttle control on the engine not working the engine stayed in forward and when Operator1 pulled back on the shift controls the engine received more gas causing the vessel to increase in speed. With the throttle controls stuck at maximum horsepower Vessel 1 increased in speed until it was on plane. The vessel stayed on plane for approximately 100 yards until the canal made a 90 degree turn to the left. 
   
  Operator1 was unable to make the sharp turn causing the starboard side of Vessel 1 to impact the starboard side of Vessel 2 which was tied to the dock. When Vessel 1 made contact with Vessel 2 to the impacted caused Vessel 1 to heel to the port leaving propeller marks on the starboard side of Vessel 2 just above the water line. Due to the impact Vessel 1 reduced speed but Operator1 was unable to stop the engine. With the throttle control on the engine still stuck in the open position the vessel increased speed and came back on plane. He continued down the canal and made a 90 degree turn to the starboard, down another canal leading to the exit of the canal system in Eden Pines. 
  
  Vessel 1 continued down the canal for approximately 100 yards until Operator1 was able to turn the motor off. Once to the motor was off Vessel 1 came off plane and drifted to a nearby seawall. I boarded vessel to inspect the shift controls and I started the vessel with the shift controls in neutral. Upon starting the motor the vessel jerked forward and the RPMs accelerated. I immediately turned the motor off.
