Shear pin for Native Watercraft Mariner Propel

[UltimateBobWPB]

I checked the Austin and the Native Watercraft Propel Easy Cruz Kit is $115.00. I realize if I had catastrophe damage to the prop it would really be handy to have the whole kit in my tool kit but I really don't want to invest that much right now. Anyone with a kit that could take a look at the pin and let me know the size I might get for a few buck. Thanks
