    ? on 15/18R 3 blade

    There has been alot of talk about the 15/19 for the RXP. What about the 15/18 for the RXT? Is anyone using it? what is the prop of choice for the stage 2 or stage 2+. Are people just using the 13/19 4 blade thats in rivas stage 2 kit? I'm hoping to get to stage 2 sometime this summer. I'm just short an external intercooler and a prop to get there. Thinking i might get the prop first-cheaper than IC. Thought if i could turn the three blade that it might be the hot ticket. Any thoughts?

    Matthew, D and S Pro is using the 15/18 on his RXT which is lightly modded and he's seeing excellent results. Im sure he'll be chiming in.

    well I went out today with the 14/19R prop on my RXT with B-Kit. This prop is awsome out of the Hole I rode with some fast ski`s today 78-80 mph and I had the hole shot by several boat lengths and then they would move on past me, my top end was down about .5 from the 14/19.5 solas I am sending it off for some magic to help with the topend as I was on the limiter fairly easy

    if I keep the hole shot and get the topend up by a couple of MPH the 3 blade will be the way to go

    So you think that with my setup a 14/19 3 blade will work nice shhr? With some magic done to it...Is there a need to change anything else when putting a 3 blade on? Or just slap it in there?

    Geo,

    Riva put out the 14-19R three blade for a StgIII RXP and the 13-18R three blade for the StgIII RXT.

    With that in mind, you would be better off with the Solas 14-19R four blade made for the StgII OR try the new Riva/Skat 13-18R three blade if you want better bottom end and or might step up to StgIII in the future.

    There is a price difference to consider as well. You can also find people that have moved from StgII to StgIII that have used 14-19R four blade props for sale. I just so happen to have one with low hours that is stock and not tweaked if you are interested.

    I really dont see how the 13/18R is enough prop for the stage 3 even on a RXT I was all over the limiter with the 14/19R and I still run the stock ECU but with the B-KIT
    GEO I would try the 14/19R based on what you have I can tell you that the Holeshot is awsome the only difference between your ski and mine is the SC and about 2# of boost so if everything else is ok I would try the 14/19R

    I do not complain at all for my holeshot now, just top end for the time being. I will take it out on Sunday, hopefully I can set-up a quick 4" intake and see how much more rpms I get. Then on Monday I will take it out and send it to Jerry for a repitch as needed.

    It's just that I talked to a buddy of mine in Tampa and he recomended the 3 blade...But he mostly does 1/4 mile runs and such...
