Thanks - based on that, it doesn't look repairable, but I've posted a photo in case someone has a different opinion. This is the forward end of the Mirage drive well on a 2009 Outback.
I have a hobie 2010 AI with turbo Fins that has just developed an identical crack after two years. Since I was aware of the issue, I took reasonable precautions during transport to prevent this.
I don't think transporting your Hobie has anything to do with the cracks. Since I live on the lake my Hobies sit upside down on my dock when not in use. No transporting, but still cracks. Heavy use with turbo fins may be the common link.
Seems that transport is probably not the cause which redirects to user and or equipment issues. I am really racking my brain here. I love the hobie craft - especially the peddle mirage drive since I have damaged shoulder. This seriously worries me because as a user I cannot see that there is anything I am doing wrong.
It seems to me that the well design may be just borderline when it comes to strength and reliability and it is likely that the problem will reoccur and short of abandoning the mirage drive I am powerless to prevent it.
