Prop

[Justjoe]

I have a 1987 70hp merc. I'm looking into getting a new prop but can't seem to find the pitch on the prop I have. Usually they have the diameter and pitch marked somewhere on the prop. The only thing I can find is (PM 319 cup) stamped on the hub around the spline. Are these merc numbers and could you tell me what pitch it is?
Again I thank you in advance

Those are not Merc numbers. Are those the only numbers on the entire prop?

Yes those are the only numbers. I'm at a loss trying to figure out what pitch this prop is any suggestions?
