After the propeller is removed, I pulled/pryed on the propeller hub very hard but carefully to pull it off the shaft!!!
Then the shaft and gear slipped out of the housing very easily. There is also a metal shaft bushing that slid out as well.
One of the parts I purchased had a gear and shaft attached so I used that. I also replaced the small gear on the motor shaft as that had some wear on it as well. That pulled off hard (but much easier that the propeller shaft) .
The motor shaft was smooth, were as the prop-shaft was knurled on the ends, thus making for a much tighter fit.
