I've seen a few boats with some pretty nasty spider cracks around the motor mount. I was thinking about putting some 1/8" plastic between the mount and transom. Thoughts?

There's three layers of 1/2" ply and some glass in the transom. I did the best I could during that install but no guarantee that the transom fiberglass is totally flex free while under load
Gelcoat is very brittle and will crack easily under stress and it doesn't take much stress. Because it is gelcoat, it is only cosmetic. I see little advantage to adding a sheet of some plastic to the installation. The stress will transmit through the mounting bolts. Make sure the bolts are tight and the plywood backing is large enough to spread the load.
I figured a lot of the cracks would be from the sharp edge of the mount. As always, thanks for your input Dave!
