Dumb question here, sorry. I am just getting back into boats after 15 years, and just bought a 31 Sonic with Imco drives. I need to buy prop nuts, they are 1-1/4 shafts. Will standard Merc ones work?

typing error.

If I recall correctly IMCO lists that prop nut as 3/4-16 and Mercruiser for Alpha thru Bravo 1's list it as .750-16 so yes and even an Alpha prop nut should work.
