    Prop change

    So will taking out my stock Rxt-X impeller and replacing with a
    15-22 show me more holeshot?
    Im gonna have Jawz do it eventually,but was wondering
    if it would be worth it to change
    Thanks in advance

    I could really care less or anymore top speed as i fell plenty comfortable
    with the speed it goes.
    MY RPM this weekend on a glassy river was 8060

    Is Jaws still charging $800 to tweak a prop?

    I'm curious as to other's opinions on this too.

    I've got a 15/22R installed, and I want to say that there's more accelleration down low. Hard for me to tell as I didn't fully tighten the damn nose cone on the prop and it worked it's way about 2" up the driveshaft causing cavitation out of the hole. I also sucked up some fishing line and plant material that day as well, which decided to stay in the pump, behind the prop until I removed it this past Friday. I fixed the prop cone as well on Friday, but it was too cold/rainy here in MI this past weekend to ride most of the time.

    Even when I first put it in the water after installing the prop, I thought I may have lost a little holeshot and that "hit" of accelleration if you punch it at say 40mph. It does seem that the 15/22R will cavitate out of the hole a little more than stock, but I won't know for sure until Thursday since this will be the first ride since the "fix" (going out after work for a few hours to try it out on a smooth lake).

    All that said, I still gained about 1.5mph by switching to this prop. And even with the "plugged up" dirty pump and F'ed nose cone there was still more accelleration in the upper speeds. If I go say 2/3 throttle from a dead stop and then WOT once I'm on plane (1 second later lol), it pulls like a MF'er.

    OH.. and I should have asked first... do you have any other mods on the ski??? If you don't, I would at least get a 3" Riva intake so that you make enough power to spin the 15/22R.

    I replaced my stock prop with a 15/22R, I was running the stock prop around 8100-8120. My holeshot went down, excessive cavitation, and I was bouncing off the rev limited like crazy 8200-8220 (I took it off till I get the reduction nozzel) then will try again. It seem to pull good and top speed was around the same (mid 69s GPS) was a bit choppy... not glass (but still bouncing off the rev limiter) going to add some pitch to my stock prop and bring down to around 8020 or so

    Jaws

    Yeah, I wonder if Jawz has come down at all on the price. I am looking at that option the winter.

    Well,This thread has talked me out of changing it until i get the jawz deal.
    I love the holeshot and all i care about is making it better.
    The cavitation stuff warned me off

    Yeah... realize that when I say cavitation, I'm talking about not even 1 second of it and I'm making a little more power than a stock X (not much, but a little). I'm also a 335lb+ rider, so ski's usually cavitate a little more for me than others.

    Accelleration from "low speeds" is def. improved over stock with my mods, just that 0mph dead dig shows the cav. Pulling out of corners at speed is DEF. stronger.

    My experience so far, with 3 mods a 5+mph gain consistantly (more for my lighter friends) with an intake grate, a 3" air intake and a prop. I don't count the exhaust resonator removal or cut reverse bucket because everyone says no real gain from them. Havent' even filled the ride plate holes yet.

    I'll post results in this thread Thursday evening (pump is cleaned out and cone reinstalled). I'm going for a ride after work.

    1 second of cavitation on initial throttle is a long time,I like that instant hang on feeling,but want more.

    Sure I will..... When Riva matches my acceleration and price.
