oring on the crankshaft?  Assuming you mean the shift lever shaft.  This is a fairly common problem, but usually on the smaller models with a shorter shift lever shaft.  You are going to have to pull the powerhead off to change this oring, so you may want to check the crankcase drain, along with the coolant water drain/spray underneath the lower cylinder water jacket.  This little hole is often plugged and is there to add a little extra water to the top of the exhaust hsg where the hot exhaust leaves the powerhead.
