What sizes are the prop nuts on Bravo III

[High Cs]

I have the OEM service manual but I don't see where the sizes are shown for the prop nuts. The outer looks to be about 1-7/16? and the inner is much larger.

But seriously, 1-7/16" is the wrench that removes the rear nut,

The Mercruiser tool for the inner nut measures about 2-13/16"
The part number for that socket is 91-805457-1

Prop nuts are 1 7/16" small nut and 2 3/4" large nut.

One of these wrenches is real handy, fits both nuts.
