Thread: '56 Evinrude Lightwin, prop shear pin ?

Hello, I have a 1956 Evininrude 3 hp Lightwin motor. Hit a rock and broke the shear/drive pin. The pin was 1/8" solid steel . I replaced it with a 1/8" roll pin. Someone told me to use a brass pin instead beacuase the hardend roll pin would cause damage.. My question is will the brass shear to easily makeing me replace it with every bump of a stick ot graze of a stump ? Or will the roll pin be to hard and cause damage to the prop or shaft ? Since it had a solid steel pin it seems a roll pin would be weaker and break easier than the original steel pin yet hold up better and longer than brass. I also have 1/8" mild steel rod that is softer, but is harder and tougher than brass, would that be a better compromise ? Any advice or input ? -Thanks
