Need help on transom thickness!

[thrillhouse700]

I have been searching for transom thickness in the mercruiser manual and i am getting frustrated that I can't find it. I could have sworn that the transom thickness spec was 2-2 1/4"

I know I found it on a mercruiser website not the book. If anyone has this website please post up. thank you.

I have seen it listed in a few resto threads from anywhere between 1-3/4" to 2-1/2"

I have a Mercury Mercruiser gasoline engines sterndrive installation manual for Alpha and Bravo that shows

I did 2 inches of wood 2- 3/4 inch plywood and 1/2 around the outdrive opening. The alum hull made up the rest.

Transom Thickness and Surface
IMPORTANT: Transom thickness and surface plane (flatness) must be controlled
where the sterndrive unit mounts.
Transom Specifications
Thickness Between 2 - 2-1/4 in. (51 - 57 mm) for 8 in. (203 mm) to either
side of the vertical centerline
Parallelism Inner and outer surfaces must be parallel within 1/8 in. (3 mm)
Flatness Transom surfaces in area where transom assembly will be
mounted (includes vertical as well as horizontal dimensions):
Inner Surface ? Flat within1/8 in. (3 mm)
Outer Surface ? Flat within1/16 in. (2 mm)
