Travelling southward on Columbia towards St. Johns, OR.  Boat was following with and inner tuver.  I watned to check my boat because it was acting wierd.  I throttled up and got 100-200 yards ahead of the other obat and steered a bit to the right to get out of his way-slowed down and hsut off motor.  Strated checking boat when I heard yelling.  I turned around and toward stern to see other boating coming struaght at us .  We yelled and swung awrms around.  Passenger in his boat started screaming just before striking the ream of boat and driving it up over the rear of mine; landing in the water to teh left of my boat.  Upon impact my son and P1 were thrown to the floor and on the seat.  My son was already sitting ont the floor so he was mostly thrown forward.  I was thrown towards the widshield and on to the seat on top of P2.
