    If you dont already have your OPAS removed youll need to invest in a set of OPAS block offs....Here is what i am talking about:

    You will also need a 2 3/4 inch hole saw for drilling the hole through the back of the hull..And some Good silicone..Most of us use "Right Stuff" by permatex..This Chit works great..And dont be stingy on the silicone..seal that sucker up...

    With this waterbox your ski will sound just about like the one in the video.
    As far as what the kit will come with i dont know but i can tell you you are gonna need a 2 3/4 inch hole saw and some good silicone preferable "Right Stuff"...If Riva doesnt offer it with their box you are gonna need an exhaust tip and two silicone coupler..Your also gonna want some good clamps for the couplers..thats about it...
