91-4 PS190 prop to hull distance?

I just put a new ACME 541 prop on my 92 PS 190 and was wondering what distance others might have from the top of the prop to the bottom of the boat. I have 2 3/8". Or if any one has a distance from the center of prop shaft to the bottom of the boat that would be just as good if not better.
I would really like to see if the prop shaft angle changed from 91 to 94. Thank you to any one that can help with this.

I have a 91 PS 190 the top of the prop is about 2 3/4" and the center of the shaft is about 9" on center.
What measurement do you have to the center?

Andre, if you have time can you give us a measurement on your 94. I expect it to be the same but would love to see what you have. I have an older thread with pictures of my boat with the Original OJ vs a new 541. I was really surprised what the 541 did with the rooster tail. Speed to 36 was much improved but that is all.
