1970s Mercury 110 - 9.8 - Prop Shaft Thread

[MercyMerc]

Hi - Had to wrestle with a puller to get a prop off a 110 Series (9.8 hp).
Would really like to go over the threads with a die, there was sadly a bit of damage done to the first couple threads. Can't seem to find anywhere online what the actual thread size and pitch is.

The Prop nut# is 64075A1
The Shaft # is 75667A2

Much appreciated!

Best guess: a 3/8 coarse.
