    2006-rxp-grinding nozzle bigger

    I was told to grind my stock exit nozzle a little bit to bring up my rpm's, after the mods I put on,
    has anyone else done this with success?
    It is the inner nozzle not the steering nozzel correct??

    thanks,

    I wouldn't do that......have the impeller re-pitched.

    A machine shop can bore it... If it doesn't achieve the desired result, you can't go back. You can play with pitch with minimal effort without fear of an irreversible mod. Good luck!

    I was curious about this also, Would the larger size give better acceleration as well?

    yes.

    slightly lower top speed tho.

    Best all around IMO is the 83mm RXP nozzle, 81mm will give better topspeed but does hurt accel a bit.

    the bigger the nozzle great volume but the less velocity the water comming out will have ..think of a garden hose no nozzle it kinda falls out ..put a nozzle with a small hole it shoots out...more speed but it takes forever to fill the bucket..

    the larger the nozzle the less restriction on or load on the engine..this is why your rpms come up..but more volume the extra volume helps with acceleration ..but doesnt have enough velocity for top speed ..hence the 87 nozzle on the rxpx..

    i agree dont boar you stock nozzle..get the adjustable ring one..or repitch your prop

    the adjustable ring one ..is nice for the changes in the weather it is quick and easy on the boat at the ramp..

    if money is really tight watch the want ads sometimes they come through ..and you can save 100 bucks or so..over new..but you may have to wait awhile..
