Frankr mentions the importance of the o-ring at the top of the drive shaft.
I have wondered about its reason for being.
I almost know now. To keep water out of the area where drive shaft meets crank.
But, how would it get up there? Under normal use any way.
As always, these posts make me re-think every thing.
I took the head off of one of my CD motors thinking I had left it out.
It was there.
Damn, which motor was it?
Must be, is probably the 68′ 9.5! Dang, not again!

The crankshaft/driveshaft junction is inside the exhaust housing. Also in that area are hot water that has gone through the powerhead and discharged to cool the exhaust housing. Worse than that, you have the exhaust with all manner of acids and other byproducts of combustion. In other words it a nasty place that you wouldn’t like to live in.
