    Impeller decision?

    I have a 08' rxpx that cavitates bad and hookup out of the turn sucks. Plus im only getting about 69.5 mph top speed. I think i should be going faster. Any impeller suggestions that would get me better holeshot and speed?
    Mods- 4"air intake, Riva sponsons & opas, Skat-Trak 15/19, ecu 8650.

    Welcome to the forum

    You will want this impeller

    and the RXP nozzle (83mm)
    It's item 27 on this page of the OEM parts store

    You'll also want a new wear ring. Item 2 on the same page in the OE store

    Sounds like my 08. Mine was the same way after some light mods. Sucker would daym near sit still and bang on the rev limiter on a hard start. That was also with the 15/19 solas.

    Right now I'm running a 15/24 yup,24 Pulls her hard on a hot day but the holeshot is back and on a cool day it will still break 8k. 74+ on the GPS. Now I just need a few mor mods to over power this prop
