I have been thinking about this overnight...
How about this:
Remove the A/C unit as described in previous post.
Completely dry the plywood if wet or damp.
Get a section of channel iron where the channel is the same thickness as the plywood and the sides are at least 2 inches in length.
From the A/C opening, cut the channel iron to the length of the opening at the sides where the plywood seam is located. Curve the cut ends with a saw or grinder.
Press the two ends of the plywood together so they are even with each other and slide/drive the channel iron over both sections of plywood, making them even with each other. The channel iron should be in between the rubber roof membrane and the plywood at the top side so that the rubber covers the channel iron on top. If there is a decorative payer of ceiling then the same on the underside so that the channel iron only wraps the plywood and not the coverings.
from inside the rig, drive short screws through the channel iron and in to the plywood making sure they do not go all the way through the plywood so that the channel iron does not slip.
This should gusset and strengthen the opening as well as level the section so that the A/C will seal properly in the opening.
Could even use some epoxy on the plywood to help make the repair permanent and more solid.
Then get a NEW A/C seal and put the unit back in the hole after everything (including the epoxy if used is dry.
