            The prop looks like from a OMC 10 or 15hp.What is the pitch and diameter.

              I’m thinking the prop might be from a 3 hp OMC and I’m pretty sure the crank is from a 15 hp, 18 hp or 22 cubic inch 25 hp OMC. I wish I could be more specific than that; but that’s all I got…..

              Long live American manufacturing!

                I immediately said JW-10 prop, but that ain’t right. Hub is wrong. Now I’m thinking a McCulloch/Sears.
                Agreed, the crank probably is a 22 cu/in OMC.

                    What is the inside diameter of the hole in the hub for the prop shaft? I’m thinkin’ early to mid 1950s small OMC – maybe 7-1/2 HP?

                        The crank sure looks like what I use in the 22ci pre 1976 omc engines. Is it for sale? Thanks
