When OMC first rolled out the Cobra drive, one of the selling points was
that the transom cutout was identical with Mercruiser, thereby
facilitating an easy conversion in the hopes that OMC might take a
larger bite out of Mercruiser's dominant market share.

As far as I know, they are the same. Of course you can probably find out
for sure by looking up parts and doing a comparison. Or asking an
impartial mechanic that you trust.

Unfortunately we are 110 miles from water so finding an impartial
mechanic/yard is difficult. But am very happy to hear that the holes are
the same or at least similar. Thanks
