Have a 2010 in for overhaul with major crack issues. Stay tuned for the repair process.  :-O

This is nothing new, all 2008-2012 models are susceptible. I've talked about it in detail over the years, the following link will explain everything. http://www.improvingyourmokai.com/index.php/topic,671.0.html

Yup, pretty bad. Should have a video next week.

Will use the same process I did for mine last year that has been holding up very well. Filling the void under the pump deck with HDPE so both planes are connected, lots welding to join the cracks, polyurethane layer over those areas inside, aluminum brace outside, stainless mesh melted into the intake tunnel crack for reinforcement there, then expanding foam inside to finishing locking everything together.

Tom, what thickness hdpe sheet did you use for the support on yours? Also do you still make/stock the stiffening plate for the back of the hull where the pump goes through? Thanks

You will need two pieces 1/4" thick and then stack them where needed. For $10 I can send you the template for the stiffening plate, but I've never made them for anyone unless I had their boat here to install it. Can't make one without it.

Fill up as much of that area under the pump as possible,  the more and tighter the better. And be sure to dam the drain plug so you don't foam over it, wear latex gloves or equivalent. Messy stuff.

What's the average charge to do a crack repair?

Good to know. Sounds like a very reasonable price. How many have you repaired now?
