RedactedNarrative: On 7-4-2014 at approximately 1600 hours Operator was operating his 24 foot Bayliner boat, WY-9391-B (Boat #1) into his slip which is a floating dock north of the Casper Boat club on Alcova Reservoir. According to Operator, when his docking maneuver was nearly complete he tried to put boat #1 into reverse to stop the vessel from hitting the permanent dock on shore. Operator stated the boat had a mechanical malfunction with the shift controller "jamming" it in forward while shifting into reverse. Additionally, Operator said his engine throttled up at the same time, causing him to "run up" onto the permanent dock directly in front of boat #1. Operator stated his boat broke off a power post while on the dock and slid back into the water striking boat #2 in the starboard aft causing "paint damage" Boat #2, which shared the same slip with Operator's boat #1 ,was unoccupied, tied to the dock and covered. 
  
  Operator stated he reported the incident to the boat club personnel but never thought to report it to any law enforcement due to the minor damage that was caused. Operator also said he had exchanged information with V2 owner and turned in a claim with his insurance company, Foremost Insurance. An interview with boat #2 owner V2 owner revealed a repair cost estimate of $8900 for fiberglass work and paint. V2 owner also stated the boat had damage to the port side due to a subsequent collision with the floating dock to the west. V2 owner said boat #2 had to go to Oklahoma to be worked on. 
  
  Operator failed to report the incident to any law enforcement agency immediately contrary to Wyoming law. On 7-15-14, I (Game Warden), contacted Operator after hearing about the incident through local sheriff's contacts and social media. Operator confirmed the boat accident, apologized and filled out a Wyoming Boat Accident Report From. Operator was issued a written warning for failing to immediately report a boat accident. 
  
  According to Operator, he will be ordering a new throttle to replace the one boat #1 currently has. However, due to the length of time between the boat accident and when I was notified, I cannot determine if the mechanical malfunction occurred. Without an immediately on scene investigation, I cannot know was or was not done to boat #1 since the accident.
