One of the passengers of the boat smelled smoke and observed smoke coming from the motor hatch.

Operator1 was unable to reach the fire extinguisher as it was located inside of the motor hatch. San Bernardino County Sheriff Deputy S. Cook observed the boat on fire and quickly took all occupants on board of his patrol boat. Lake Havasu Fire Department responded and fully extinguished the boat fire. No subjects were injured as a result of the fire.
