I have a one month old Nitro Z21 with a Mercury Pro XS 250. It has a Fury 23P prop. The hub in this prop is a Mercury Marine Racing Heavy Duty 1.25 Propeller Shaft Hub Kit Assembly 840389K06. I have come across a used prop to keep in my boat. I also need to buy a new Hub. Since the Hub is around $120 to $160. Is there an aftermarket Hub that I can use, since this will be a spare to get me home if needed?
