HI RICHARD,
I THINK YOU JUST HIJACKED MY POST, BUT THATS FINE WITH ME!
I am no expert but did a fair amount of research on cracking in the Hobie Outbacks. If you found cracks on the exterior I would pull the covers and look closely at the interior reinforcement tubes around the drive well. That was/ is one common area prone to stress cracks, another is the through holes where you would attach your wheels.
As far a fixes, welding the interior is a problem due to lack of access. Fiberglass is a no go. A couple guys used specially formulated plastic glues and claimed success at the time of repair, who knows how long they lasted. JB has a couple of choices but dont just use any epoxy and be careful on what you choose!
Interior shot what to look for.
https://www.stripersonline.com/image_re ... ?i=1636129This repair looks substandard, but who knows! I saw another guys repair who used a plastic specific epoxy or glue and he essentially cut pieces of PVC to fit around those interior reinforcing tubes and filled them with the stuff.
I did plastic welded one kayak. I was pressure washing my house and the dam thing walked its way over to a kayak and melted a hole in it. I got the job done with A regular plastic bucket and milk jug, it wasn't pretty but it worked. Practice your technique first and make sure the plastic is compatible.
Found it! Good Luck, Keep me postedhttps://www.hobie.com/forums/viewtopic. ... ck#p301976 the link:
