I have a 1974 Johnson 25hp and would like to purchase some spare prop shear pins and do not know the size or how to find out. Any help greatly appreciated, thanks.
Another question about pins. My motor has a stainles drive pin in it.
I purchased another pin from my local dealer and it is brass, which is better to use? The brass seems that it would shear fast, possibly too fast and the stainless I am thinking would be too much to shear. Can you tell me what the OEM is?

307949 DRIVE Pin is 3/16" x 1-3/8" Stainless Steel, and is the correct one for your motor. The rubber hub in the propeller absorbs most shocks and the pin is not supposed to shear. But never say never, it is possible to shear it if you really mortally clobber something, so carry a spare--and a cotter pin and pair of pliers.
