Are you doing a trim setup? Waveraiders have a stock trim system. The stock raider reduction nozzle has mounting holes for the trim ring that the steering nozzle mounts to. 00 Superjet has no trim from the factory so the reduction nozzle is different from the raiders. They are all for a 144mm pump though.
If the reduction nozzle has mounting holes horizontal (left and right of the outlet), it is for a trim setup. (Raider style or 08+ Superjet)
If the nozzle has mounting holes top and bottom of the outlet, it is a non-trim setup. (96-07 Superjet)
Just a heads up if you arent going to run trim.
