Hopefully everything worked out for you.  Get it out on the water and test it out.  Catch a few fish while you do, I'm sure you've been dying to.

Not sure what a floor kit is, but suspect that it is part of the fix.  My guess would be that it adds stiffness to the bottom, preventing the flexing which would have caused the problem, akin to bulkheads in larger boats.

Either way, it's a good thing to have done. 

Hope everything from this point on works out to your satisfaction.

Or the floor kit just keeps him from seeing more leaks and bad looking repairs while the boat is still under warranty  ;D ;D ;D

anymore updates???????????????
