RedactedNarrative: Operator agreed to take the potential buyer for a test drive and he claimed that while the potential buyer was operating the vessel, a mechanical failure with the throttle linkage resulted in vessel 1 piercing the seawall. The potential buyer increased the throttle to the motor believing that the vessel was in reverse, when in fact due to the throttle linkage malfunction, the vessel was still in forward gear. This caused vessel 1 to rapidly accelerate into the seawall. 
  
  Operator took over the controls and was able to get vessel 1 into reverse, vessel 1 then struck vessel 2, damaging vessel 2's swim ladder. Operator said he then left the scene and didn't report the incident because he was scared. Operator was issued a written warning for failure to report a property damage boat accident within 24 hours as required.
