RedactedNarrative: INITIAL CALL:
  On April 05, 2019, I was dispatched to a vessel on fire and sinking in Sand Hollow Reservoir. While enroute, dispatch informed me that there were 6 people on board. I instructed dispatch to tell the people on board to put on their PFD's (personal flotation device).
  
  ON SCENE / EAST OF THE ISLAND:
  Arriving on scene, I could see no visible smoke or flames. I instructed the remaining passengers on board to put on their PFD. The captain of the boat said that he had put the fire out with his fire extinguisher, but the fire had melted a rubber gasket at the boats waterline.  I boarded the boat and had OPERATOR open the engine bay. The boat was a 27 foot twin engine Bayliner.  The fire had occurred in the portside engine and had the yellow powder all over the engine from the fire extinguisher.  I verified that the fire was out and that the boat would be able to be towed back to the dock. I also observed water coming into the boat from the gimbal area. Water would only come in when the gasket around the gimbal would dip below the water line. The bilge pump was keeping up with the water coming into the boat, but did cause an electrical short in both port and starboard engines. I towed the boat back to the dock.
  
  INVESTIGATION/DAMAGE:
  OPERATOR said that the boat was operating normally until he saw the smoke coming from the engine compartment. He stopped the boat and opened the compartment were the smoke was coming from. OPERATOR used his marine fire extinguisher on the portside engine and the smoke stopped. He never saw flames, only a lot of smoke. After OPERATOR put out the fire, he noticed one of the rubber hoses on the backside of the port engine had come loose and got caught in the engine's pulleys.
  
  I opened the engine bay and found the hose that had come loose off the back of the engine. It appears that when the hose came off, it got caught in the pulley assembly and that generated enough heat to start the fire. The heat from the fire was hot enough to melt the gasket around the gimbal causing the water to come in when the top of the port gimbal went below the water line. Once the boat was out of the water, I took a picture of the port gimbal from the outside of the boat. There was possible electrical damage to both engines (neither would start), belts, rubber hosed, pulleys, and the rubber gasket around the gimbal on the port engine.
