I have a 2007 38ZR, 525’s, XR. We noticed stress cracks on the props which I’ve learned isn’t uncommon with the high X dimension of the ZR’s. I’m currently running Maximus 32’s and was wondering if anyone with the same setup was running Hering? I know Bblades offers the test program, but was hopeful to get a few opinions as well. I understand the props are very different in trailing edge, rake etc, and was curious if Hering was also a good option for high X dimension. Thanks for your feedback

I have the same setup , I tried 5 blade herrings and the cruise speed was not there as for top end about the same. I run Maximus 33 and seem to work the best for me . If your props have stress cracks you are running on borrowed time.

Definitely time to change props. My ZRC is a completely different set up so I can't help with size or type. sorry
