RedactedNarrative: Vessel #1 was being launched into the water at the Houston Recreation boat ramp on Winston County Road 3124. After being backed into the water, the operator of vessel #1 attempted to start the engine. The operator of vessel #1 stated that he heard a loud pop, and then observed flames coming from the engine area. The operator of vessel #1 was forced to abandon the vessel. Vessel #1 drifted into the walkway of the boat dock at the Houston Recreation Area. This resulted in vessel #1 becoming wedged underneath the walkway, and subsequently burning the walkway.
