RedactedNarrative: The outboard motor on vessel 1 (V1) caught fire as its owner/operator attempted to turn it on. The owner/operator was uninjured. The outboard motor was the only part of V1 that was damaged. 
  
  V1 was moored behind a residence. OP1 attempted to turn on V1’s outboard motor, heard an audible pop and observed the motor catch fire. Palm Beach County Fire Rescue responded to the residence and extinguished the fire in the outboard motor. 
  
  The outboard motor of V1 was burned internally and externally from the fire. No other portions of the boat were damaged. 
  
  OP1 was uninjured from the incident. With the scope of my training the apparent cause of the fire within the outboard motor is unknown.
