What I mean is you can drill pattern corresponding to lowest position of motor. Place motor squarely on transom and drill using bolt holes as guides.
Alternatively you can raise motor with wood block or something and again use bolt holes as guides for drilling. But then I would keep distance from top holes to top of transom not much less than thickness of transom. i.e 40 mm.
