Narrative:

On pushback; captain was getting 'salute' from push crew as the right engine was starting. Following a normal start procedure; I moved the fuel control switch to run and was monitoring the 'light off.' the engine lit off and then I saw the egt number turn red and immediately called out; 'hot start.' the captain said; 'kill the fuel.' I moved the fuel control switch to cutoff and began to motor the engine for a minimum of 30 seconds. The egt continued to climb while motoring the engine to peak at 712 degrees C. The engine start switch was selected by the captain to off after about 40 seconds of motoring. I then looked in the QRH to verify the aborted engine start - ground procedure was complete. Returned to gate and maintenance said aircraft had to be taken out of service for borescope inspection on the right engine.
