I got this prop today. Stamped 9X10, with the 10 stamped out, then 11. So it was a 9×10 that was tweaked to a 9×11.

Left hand rotation. ID is 0.81, length through is 2". Shear pin diameter is 0.25".

Any ideas?

I am going to go with racing prop and I would lean toward early johnson.

Not a Johnson because Johnson is RH rotation.

If I were at my shop I could give an idea of what it would fit and I’m leaning towards Evinrude Speeditwin/Speedifour with pre-war lower unit, but I’m only guessing right now…

I would say Pre War Speeditwin (0.788" prop shaft) I think I’m running a 10 X 12 on mine.

Looks like an OJ that would fit the Speeditwin, Speedifour or Big Four of the pre-war models as the post war had a 1" prop shaft.

I can make out "Michigan AJC" on the hub end nearest the pin hole, but the rest is buggered up. Can’t make out any more.

Michigan Wheel’s AJ (Aqua Jet) series were copies of the Johnson Propellers made in Oakland California – the so called "OJs" I have a copy of the OJ catalog on Walagata.com, but am blocked from the site despite having paid for another seven months. This despite daily messages to there customer service department for over two weeks. . . . . . 👿
