We've installed a FMR on our '08 PW Lexor. I could not find a "bolt on" (i.e., it simply bolts on to existing holes in the frame), but we were able to use a universal hitch, though it did take some "fiddling" with it to get it to work.
Measure, then measure again, and then measure one more time.
Putting it up in the air, as opposed to simply rolling underneath, is a REAL help in getting it done.
It did require some modifications to the fiberglass fascia, or "chin" as some call it.
Though we use it for different reasons than launching or retrieving a boat, it works perfectly for us.
Cheers.
