RedactedNarrative: Vessel #1 was launched on the public launch ramp at Pleasant Hill Lake area E launch ramp and was floating beside the courtesy dock. The operator attempted to start the motor several times and then noticed smoke coming from the engine compartment. The operator opened the engine hatch to further inspect and observed flames in the area of the engine. The operator shut the hatch and all the occupants exited the boat into the water next to the courtesy dock and the vessel became engulfed in flames.  The vessel was pushed away from the dock to prevent damage to other boats and structures. The fire department responded and extinguished the fire and the boat was recovered.  The vessel was a total loss.  A fire extinguisher was on the vessel but wasn’t used by the operator.
