Riva Sponsons..... Be Aware.
Has this happened to anyone. Was out today doing some closed coursed racing and when I pulled my ski out of the water I notice one of my sponsons were missing. I know it was not that I didn't screw them in properly because the screws were still in the ski and looks as though they were ripped out cause it's just the head that is missing.
I know it's not that someone hit me because the ski has no scratches. Just a few questions...... has this ever happened before and right now i'm running the sponsons as they are in the pics and the ski is extremely hard to turn ??? Should I put back on the stock sponsons or did I just get to used to the nice ride of the RIVA sponsons. BTW I'm not bashing the RIVA sponsons or anything, they are the most awesome sponsons I've ever used and compared to the stock ones they are a blast of a difference. I'm not discouraging anyone not to buy them as it kinda the opposite. But just a heads up. I probably got the one bad melon in the group.

We run Riva on the 2008 and they are faultless for us. R&D was a problem child, blades kept bending. I am surprised. Maybe just the quality of the bolts, cause your blade certainly didn't break.

remove the broken bolts.( my bet is they were over tightened when installed )
Just make your own set of plates.......then you can make them as aggressive as you like
you can use the existing backing plates , just make new plates like above
either make them deeper or copy the Riva ones
you can use either alloy or hard plastic material ( forgot the name of the stuff I got )
either way some brain power will fix it cheaply and quickly

You should be fine using SS just don't over tighten them.
Use blue lock-tite and just snug them down.

But in the inter rim should I leave as is or put back on stock sponsons ????

Put it back either way, just don't over tighten the bolts.
