Min. transom thickness

Hey guys, what has been the thinnest transom you have seen that had no issues being too thin to keep the input shaft from bottoming out in the coupler? Alpha/Bravo setup. I know Merc specs 2" as a min, but sure that includes a saftey factor. Are we speaking 1/16", 1/8" or more under and still safe?
Thanks
 
I just looked at a boat today and the transom thickness was a hair over 1/8 as far as glass goes and it was set up for a number 3 drive .
