RedactedNarrative: On July 13, 2019 GW contacted me and advised that there was a vessel that was on fire at Lanier Point Park Boat Ramp.  Myself and Cpl. responded by boat from Aqualand Marina to the location.  Once we were on scene the boat was out of the water and operator and passenger were on land uninjured.  i asked Operator1 what had happened.  He advised to me that he started the boat and had activated the blower for the engine compartment.  Then he noticed smoke coming from the engine compartment.  When he noticed the smoke he turned the engine off.  Operator1 contacted Tow Boat USA and told them his boat was on fire and needed help.  Tow Boat told him to call 911.  Gwinnett County Fire responded to the incident and put the electrical fire, and transported the 4 occupants to the ramp while Operator1 loaded the vessel on his boat trailer.  Operator and occupants were uninjured and the vessel had electrical wire issues due to the fire.  It was determined that a tube was blocking the vents for the engine compartments blower system.
