Yamaha 20hp 4 stroke prop issue

The problem I’m having with the prop is that it produces a high pitch noise originally thought that it was A bushing in the footing making that noise after two weeks of working with it I realize that it had to be to prop.Is it damaged ? Where to get the best prop ? Have you ever bought propeller from Hex Auto Parts? The price is attractive and more reasonable than Wholesale Marine, I'd like to place an order.

Mmmm dont think its the prop...its just pushing water. Possibly the hub I suppose. But I'd be troubleshooting the mechanical related parts....spacer, washer, hub, etc, before going to buy new prop. Can you confirm the correct hub kit and its assembly installed?
