Prop size needed for replacement 50 hp johnson

[Oldnbold]

I’ve a ‘86 Johnson 50 that I knocked a sizable chunk out of aluminum prop. I need to replace. I can’t find a size stamped or marked on this aluminum prop. Anyone know the size so I can shop?

Well---- the correct prop is determined by the load the motor must push !----So please do tell what boat you have and what you do with it.

I used to go to a shop that kept a supply of used props on racks, pretty well organized for size. If you have a shop with used and salvage props, you might be able to carry yours in and find a match or get some advice.
