RedactedNarrative: The operator stated he took out the vessel for the first time this season after it was stored at a marina. When the operator, his son and dog left the dock, approximately 400 feet from the dock he heard a pop and saw smoke coming from the starboard engine. Shortly after the operator saw flames and retrieved the fire extinguisher to put the fire out. After extinguishing the fire the operator shut down the starboard engine and fired up the port engine and went back to the dock. There were no injuries reported.
