I have a 1975 merc 9.8 110 and i have the engine running real nice, but my lower unit is pretty beat up and has a carbon steel shaft. I saw a few LUs online with stainless shafts and shoft shift rods for a decent price and I was wondering if my motor will take a stainless shaft, not sure if there is a different OD on the splins from the carbon to stainless shafts?
