RedactedNarrative: On March 8th at Approx. 12:11 Operator1 was Traveling north on the Tn. river when his engine on his vessel caught fire. I interviewed Operator1, he stated that he was traveling approx. 45 mph heading toward Soddy Creek when he heard his engine make a funny noise and lose power he turned around to check on it and saw smoke, he then powered down to inspect what was happening Operator1 then saw flames coming out of the ventilation holes on the engine cowling he stated that his fire extingisher would not discharge completely and that a passing vessel gave him theirs. Operator1 used the second fire extinguisher on the fire which he stated did not put the fire out, he then used his trolling motor to take his vessel to the bank where he stated that he kicked off the engine cowling and splashed water from the lake on the fire till it when out.
