RedactedNarrative: Boat operator/owner said they were underway in the area of Cholla Bay in Roosevelt Lake when they began to see smoke and flames coming from the engine compartment. They were able to extinguish the flames using their onboard extinguishers. At that time they believed that only one engine was effected by the fire and began limping the boat back to the marina with the second engine. After traveling for a little while, they began to see smoke coming from the engine compartment once again. No flames were visable this time. 
  
  We made contact with the vessel between Cholla and the Roosevelt Bridge. We towed their vessel into the Roosevelt Marina.
