A. Ian, you are correct that my 66 sterndrive originally had only a very
thin fiberglass "skin."
The entire "structual" support was provided by the steel channel frame that
bolted a) into the floor stringers, and b) to the transom lifting eyes. On
the early sterndrives the top of the intermediate gear case was also bolted
to this frame. After 67 this frame was eliminated and all sterndrives became
floor-mounted using four points that bolted into the floor stringers. I
added the interior plywood to provide support for the Bennent trim tabs and
additional support for the lifting eyes.
I retained part of the steel frame but also added "struts" to provide fore
and aft support on the transom eyes whell towing tubes and skiers.

There's a lot of good advice on fiberglass and specifically transom repairs
on outboards over on the forums at www.fiberglassics.com
