RedactedNarrative: On 05/02/20 Vessel 1 (V1) was being operated by operator 1 (O1) on Lewis and Clark Lake in Yankton County, South Dakota with three passengers (P1, P2, P3) onboard. 
  
  O1 had just purchased V1 from a local marine dealer and was taking it out on it's first voyage. O1 ran the blower on V1 prior to starting the engine as recommended. O1 motored V1 out of Gavin's Point Bay and onto the lake in a southwest direction. O1 motored V1 on plane without issue. V1 continued on plane for approximately 5 minutes as described by occupants onboard. O1 motored V1 down and came to drift after O1 and passengers onboard smelled burning material coming from near the rear of V1. O1 opened V1's engine compartment and visible flames rose out. The exterior of V1's engine was on fire. O1 and passengers used a fire extinguisher located onboard V1 to put out the flames. Because of the damage to V1's electrical system, it's engine would not start after the fire had subsided. V1 was towed back to shore by bystanders. V1 suffered exterior damage to it's engine, electrical wiring and engine compartment during the fire.
