Sounds to me like a used shaft in SAE (US demenisions) is your best way to go, as it will give you much more in options as far as props and hardware. It may not be what you want to do, but lets look at what went wrong in the first place;
1. You lost all the hardware that holds on the prop
2. The zinc is no longer attached ?
3a. The prop fell off while under way ?
3b. The prop is gone.
5. The prop shaft is damaged ?
6. The prop shaft threads are damaged ?
Buy a shaft and prop and move on, and perhaps increase your mantinence on the shaft/prop/zinc assembly in the future.
