Merc. 115 hp Drive Shaft part number?

[frustratedboater]

All,
I have 2 questions for you...
1) I was wondering if someone can help me locate a part number for a 1993 Mercury, 115 hp, Outboard, Serial # 0D230459, EXLPTO.
2) Recommendation on finding a used shaft?

I am trying to locate a replacement, going from an extended shaft to the short shaft. I thought about replacing the entire lower unit, but that's going to be too expensive and perhaps, easier just to replace the shaft. As always, I appreciate any help...

Thank you so much. I have ordered shop manual CD's, but they are on their way... I appreciate the help.
