RedactedNarrative: Vessel 1 has just left the boat landing and started to power up the engine.  As soon as more power was applied a large bang was heard and the operator said that the motor cover blew off the engine.  He stated that the engine instantly caught fire.  He said that he panicked and did not grab the fire extinguisher but used a bucket and applied water to the fire.  He stated that he applied approximately 30 buckets of water to the engine before the fire was out.  The fie department responded but was not needed.  I responded and took a few pictures, collected information then left.
