It is a Prop for an OMC outboard, it is not an OMC Prop.
Michigan Prop 4 blade 10" Dia 11" Pitch. It would fit on the Big Twin type of Outboards; 25hp(1951-55), 28hp, 30hp(1956), 35hp(1957-59), and 40hp(1960-76, and the later commercial models).

Great! Thanks! I have a '67 Johnson 33hp that I wanted a smaller pitch prop, and I remember buying it in the event I have my family come on my boat to fish since I know the 4 blades give better hole shot. But I forgot the specs on the prop.

A four Blade loads the engine more, so it doesn't always make for better hole shot
