On the installs I’ve done personally, I’ll make up a “shelf” (a horizontal plate, with two vertical gussets) for the drive out of 3/4” premade fiberglass board, shaped to the curve of the hull; that gets epoxied, heavily tabbed and glassed onto the hull. That seems to do the trick. The drives on this size vessel generate at least 800 pounds of force; you definitely need to build with that in mind.
