Pretty much any RXP setup is fine that has the trim ring setup. The X venturi is a little bigger but still works. Just take the reverse off and plug the OPAS bolt hole off on the steering nozzle.
I've cut and modded the Yami nozzle to work very well and think Philip_gpr offers this service. Much thicker mating surface and less likely to break like the factory SD venturi.

As Duke stated there are all sorts of choices for what nozzles to use.
For a rec ski my strong preference is to use the Yamaha nozzles. Yamaha hulls typically like at least a 5 degree angle on the pump nozzle. For the size of the exit diameter 85 mm seems to be the sweet spot for top speed. The seadoo nozzles are on a 0 degree angle and most of them are smaller than the ideal 85 mm.
In order to use a Yamaha nozzle with the Seadoo pump there are a couple of choices. One option is I can machine the Yamaha nozzle to mate up properly with the Seado pump. The other choice is I am now making a nozzle adapter wedge that allows a Yamaha nozzle to mate up properly to the Seadoo pump without having to machine the mating surface. By using this wedge you can also adjust the nozzle angle. For CC the angle can be adjusted down 1 or 2 degrees and for rec riding or top speed the angle can be increased 1 or 2 degrees.

Depends on what ski (and what year if a GPR)
For a GPR, my adapter positions the Seadoo pump in the same position as if the GP1300R 2 inch spacer is being used, so if you were using GP1200R cables yes they need to be extended 2 inches (if using GP1300R cables everything is fine)
