I'd suggest working with a dealer and getting the brackets they used from 2014 or 2015+. I did this on my 2013 Mojo and it made a world of difference... the old brackets allowed the platform to move and shake the whole boat anytime a small wave hit the boat from behind and I actually had a bracket fail (but I didn't loose the platform). I think I only paid a few hundred dollars to have this done... and had the manual flow system installed at the same time.
