Michigan Prop ID?

[RumDiet]

Hi All - I have a Michigan Prop that I found in my basement - I don't recall this propeller or what boat it may have come from! it has 141/2 x 19 inscribed on the hub, so I am confident as to the size - what I don't know is whether its an OMC or Merc Prop. Also stamped on the Hub are M6046 and M8824 - which I understand are not Michigan Prop numbers - any assistance in figuring this out is appreciated.

Is the hub pressed in or removable? If pressed in, count the splines.

Thanks for the quick reply - hub is pressed - I counted 15 splines

OMC will fit Merc but Merc wont fit OMC due to spline length...

Thanks Very much
