I've meesed with outboards a while this is the first I've seen where both prop and water pump don't work. I assume it is drive shaft related. Just quit working will motoring no other symptoms. Motor still idles fine.

What is your model? If you drop the LU, is the driveshaft in one piece?

The two things are independent of each other. So, unless you have a broken drive shaft, the problems are not related.

NS25C3 2001 I'm not sure, I did notice there didn't seem to be any splines or a key just a smooth shaft.....

Are you saying the top end of the driveshaft doesn't have splines? If so, it is probably snapped off, with the splined portion stuck in the crankshaft.
