The operator and his minor child occupant sat on the personal water craft when the operator tried to start it. The vessel was never vented in which spark caused the engine to explode. Both occupants were thrown from the vessel causing major injuries to the operator; fractured pelvis, vertebra and left foot. Injuries to the child include; broken elbow and laceration on the forehead needing sutures to close. 
In the investigation it was discovered that the fuel filter did not seat properly and the engine starter did not appear new although it is alleged the part was replaced with a new starter a few weeks earlier. There are many observations that suggest otherwise. There is also evidence of corrosion on the positive battery terminal lead to the starter. The mounting holes for the starter show a long pattern of wear and are clearly oblong. Lastly, the mounting Alan screws are scalloped, a sign of progressive wear as the part was allowed to shift back and forth.
