Total thickness on my Scout transom is 2.75", about 2" of core and two .375" glass faces. I can tell you from experience that it was challenging to find a good selection of thru hull fittings that went through a transom that thick. Most fittings are designed around a much thinner wall section.

Thicker won't hurt, but for a narrow load bearing area, thinner may be adequate.
