    Stx-r pump nozzle swapped for 12f nozzle?

    Hey guys, I read that swapping the nozzle set up from a 12 or 15f onto a stxr increases throttle response. Is this true? If so what year machine and model can be the donor? Part number would help.

    Thank you guys!

    I am not sure about the 12 but the 15 was a larger diam than the stock stx-r. I am running one on my boat now with the stock pump. I will be selling my setup since i have a 155 mag pump for it. If your interested in the nozzle let me know.
