Will 2011 CX-9 rear shocks fit on a 2011 CX-7?

What is the likelihood that 2011 CX-9 rear shocks will fit on a 2011 CX-7? I am trying to beef up my rear suspension for pulling my boat. I can’t afford to buy a truck at this time. So, that’s not currently an option.

Or, does anyone have any advice on some heavier duty shocks for a 2011 Mazda CX-7?
