I don't have the info either way but I believe that boat came with a 30 HP Universal Atomic Four gasoline Engine standard or an optional 8 HP Yanmar one cylinder Diesel Engine and they probably did not have the same prop. You would need to specify what you have before anyone could answer you. I expect you have the universal as I did in my Irwin Competition 30 but unfortunately I don't remember the prop I had.
Good luck
