I just told you that they are 1/4 inch bolt holes. And no they won’t break if you use 1/4-20 Grade-8 high strength bolts. But if you use the cheap grade 3 bolts from the discount store they certainly will break.
In case you still doubt, consider they used those same bolt holes for about 30 years. Your flywheels will come off easy, compared to the 1962-up 40hp. Now those are the toughies.
