prop shaft

I bought this motor used and love it. Recently started leaking oil. I pulled the prop and the shaft to replace the seals and realized that the prop shaft was slightly bent, explaining the worn seals. The lower unit appears to be an aftermarket unit and I cannot identify the shaft. It is not the standard shaft for this motor. (s/s 0G917091. The splines are a full 3 inches long and the shaft overall is 9 inches long? The sleeve bearing carrier has a part #4208 stamped on it and the oil seal part # was a Mercury 2666022. Any ideas of a part # for this prop shaft? I need a new one.
