1970 4hp Johnson, prop hit bottom, key shear?

[ugmold]

Hi folks,

Started up my 4hp in shallow water and busted something, prop spins free, does not engage. Is there a woodruff key or something for this?

Thanks,

There is a "0203230 PIN, Propeller drive", also known as a shear pin. It transverses the prop shaft through a hole in the prop shaft. You'll need to pull the prop and it will be obvious.

About $2.

Standard drive works the same including pin.
