Cracking on rear engine cowling.....

Interesting. I have not experienced that sort of issue with my airplane.

Also as I think back about 15 years ago I hare a 70 skymaster that had a screen on the top half and disc on the bottom and the bottom kept cracking. My 80 h doesn't have the screen on top and I haven't had the cracks, just the vibrated out rivets.

No screen on my 73 G either. I'm searching as we speak for the two assemblies. Sending emails to every salvage yard Ernie has listed on his web-site. Hopefully I get lucky. The thought of wasting more time and money trying to repair my existing one again does not sound too appealing.

Have you tried doing a propeller balance? It might be worth looking into.

I was thinking prop balance too. I had some cracking around these areas in the past but since I installed the MT props no issues. I will take a photo of the cracks and we can compare.

Thanks Herb,

I have had my props balanced twice in the past. Each time after they come back from the prop shop after reseal. It has been about 3 years now. The props go out every 5 years for reseal.
