I don;t know if they even make a prop shear pin type prop mount any
more on any new motors.In years past most of the smaller OB had shear
pins in the Johnson and evinrude and some others, but splined hub was
used by the vast majority. While you may have had shear pins shear
as designed, I have also seen hubs in these props tear out at the
shear pin section as well.....so it goes both ways.
