RedactedNarrative: On 7/26/2017 around 1630, Operator was loading his 2009 Suntracker pontoon onto his trailer at Chimney Rock Marina on Herrington Lake. As Operator loaded the pontoon, he realized he needed to move up about 6 more inches to get the boat trailered. As Operator started the boat, the engine suddenly caught fire. Operator used his fire extinguisher to try and put out the fire, but it failed to extinguish the fire. Operator then got out of the pontoon, and pushed it off of the trailer and back into the lake until the Burgin Fire Department responded and extinguished the fire. There was no damage to the marina or any other property.
