I don't know the special or smart method to make propeller,
As I usually do the blade is
1. Design your blade section and prepare your coordinate profile and save as extension *.pts , this extension can be import into proe.
2. Import each section into proe and make a smooth spline curve for that coordinate and also make a guide curve as you want your blade to be.
3. Using variable section sweep or style to create you blade into solid or surface.
4. Making you hub section sketch and revolve.
5. Manage intersected portion between blade and hub as you want.
6. That's it.
