On CJ Strike Reservoir the operator of a vessel attempted to start his boat, upon ignition, he turned to look back, and saw a small fire.  He and his three passengers jumped off the vessel into the water and swam to shore.  A person that was on a tube behind the vessel jumped off when he saw the flames, and also swam to shore.  The vessel then was engulfed in flames.  The fire appeared to have started in the engine compartment.
