Buckeye,

I'm doing my 18 footer too. Transom rot looks the same. Water came in through crack on top. New transom is already epoxied in.

I cut out deck and have new nidacore deck ready to go in as soon as weather warms. The aft well is history as it added weight and just collected garbage.

The foam in my stringers looked ok but the botom was wet from stern all the way forward. I cut top and dug it all out.

You're doing a lot more work then me. I'll be at it again as soon as weather warms

Good luck
