What or how many nut/washers are used on a Fury prop (24p). I remember there was the nut, a washer, and another circular washer at the very end towards front end of LU and the prop seems to have the normal play. However after I took it to a dealer to winterize my motor the last 2 years, now my prop doesn't have the play anymore...seems a little tight. I decided to change the gear lube myself and only saw the nut, hub, then the circular washer at end of shaft. I tighten it and there's no play in the prop. Is this normal or perhaps the dealer screwed up and never put back all the correct nuts/washers? I just noticed this issue now...I was operating the boat couple times before.

TIA!!
