RedactedNarrative: V1's starboard side bow struck stationary/docked V2's starboard side outboard inside a marina as V1 was manuevering away from the vessel slip. 
  OP1 advised he was backing his vessel out of the docking slip towards a concrete wall. He then advised he threw the throttle into forward gear and struck a stationary, docked vessel on its outboard. He could not advise the reason clearly. I inspected the throttle of V1 and observed no cable malfunctions nor felt any "sticking" of the lever. It appeared to be in working condition. 
  The damage observed on V1 was minimal and included some slight bent aluminum to the starboard bow above the pontoon. 
  V2 was identified as a 2020, 27' Robalo center console vessel. It was unmanned, stationary, and securely docked in a vessel slip inside the marina at the time of collision. There was significant damage sustained to the starboard outboard from being struck by V1's bow(see attached pictures). There appeared to be internal damage to the motor under the cowling which had been ripped and broken off.
