The pilot stated that he was practicing touch and go landings. After landing, during the landing roll, when raised the flaps and added full power, the airplane veered to the right. He applied left rudder to stop the right turn and overcorrected. Then the airplane veered to the left and continued off the runway into a ditch, which resulted in substantial damage to the engine mounts. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
