As you can see, 1956 was a year of change. The propeller was changed to allow slippage under impact, and a Monel pin went with it. The reason of course was to eliminate shear pin breaking and the need to replace it on the water. At the same time the prop nut was changed to accept a longer pin. So, actually, it depends on what prop you have on it and does it have the correct nut to go with it. I suppose it depends on run what you brung on the prop and use the pin that fits the nut. If you have concerns about doing that, use brass.
