The propeller came with a Frankenstein Neptune motor I was given, and I am fairly certain it does not belong on the motor. The motor’s shaft is designed for and has a 5/32 shear pin and the prop is designed for a 3/16 shear pin. I just wanted to know if this could have been a stock prop, but now I believe that sears motors used them. Thanks for the help, hopefully I can find the correct one.
I think Neptune would have made their own props, but I do agree with Tubs in that it is one of those propellers. That being said, it was probably used on both Sears and OMC motors of smaller horsepower.
