Prop help 392v

[84tracker]

Need some ideas on what u guys are running if u have same boat I have 1983 ranger 392v with Merc 200hp. It threw a blade today and there are no markings on the prop whatsoever. New boat to me and prop shows a lot of signs of being worked/repaired so being there are no marking anywhere on it (appears to be sanded down tremendously) I don’t know where to start so any advice is truly appreciated
