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.
