The vessel was traveling at approximately 40 mph when it planed out. Due to transom/equipment failure, the engine turned right and spun around very fast. The abrupt movement threw a passenger over another passenger striking his head on the vessel. The passenger injured his forehead which required medical assistance. The operator struck his head on the windshield but did not need medical treatment.  The operator jumped out of the boat and secured a line to his vessel and proceeded to get his vessel to shore with the help of two good Samaritans. The partially submerged vessel was secured to the dock and removed by the operator.
