1988 Merc 8HP shortshaft lower unit gearcase, freshwater only, shifts good, no sign of water in oil, Overall very clean i was told it had very little use. I included photos showing length of driveshaft and where i measured from. Feel free to ask any questions. There is a photo of the serial number if you need it to verify fitment. Shipping quote is for lower 48 states only, all others ask for quote. thanks
