I recently purchased a mairage 21 prop on e-bay thinking it would work on my alpha. It appears to have a different hub design than my current prop and also takes a different thrust washer. The part number is 48-13244 21P. Can anyone tell me if I can use it for my alpha using different thrust washer and nut? If not, what numbers should I look for when purchasing a mirage 21P.

Thanks,

I just want to add that the hub is solid. That seems to be the difference and must rquire a different trust washer. I boat in the potomac river and often find myself dealing with the tide and very low water in and out of my marina channel. I would probably be asking for it to run a solid hub.
