    2013 rxp 260 problems

    Hi guys I'm hoping someone will be able to help me solve this issue I'm having. I bought a seadoo 2013 rxp 260 with 43 hours on it. I took it out for its first run and had bad cavitation of the line. So I took it into my seadoo mechanic to give it a service and look into this cavitation problem. He found the pump seal twisted and replaced it and gave the ski a full service aswell as I put on a 4 inch air intake system on and installed a worx intake grate and I also got the computer remapped to give me more power. So I just took the ski out for a run and the cavitation is still there off the line and now I'm getting 8400 rpm instead of the 8080 rpm cause of the computer which is great but I am still only hitting top speed at 115 kph. So no different top end speed from a stock ski. I'm pretty disappointed that I'm not hitting a higher top end speed aswell as having the cavitation there I'm not getting a goog hull shot out of the water. Anyone out there had a similar problem.
    Also I didn't change the wear ring as the mechanic said the ring and prop were in excellent condition.

    Without a prop change not a lot, but the ski will feel a lot better with the limiters removed.
    What are the rpm limiters set at and whats the target prop speed with that Flash?

    Put an SS ring in it.

    To be honest Sayers I'm not to sure what the flash tune was set too. I only know that I can hit 8390- 8410 rev on reasonably flat water. I saw on a free rev it was just hitting roughly 8550 revs. If you think a ss ring would be best I most defiantly will go down that path. If installing a new prop will help me get better resaults I would get one for sure!!!!! I'm after Best of both worlds with great holshot for jumping aswell as great top end speed. �� any you can recommend mate??
    i would really like to come close to hitting 75 mph

    Solas 15/20r pitched on pitch block to 14/19 worked great for me. Throw in the R&D pump seal too while you have the pump out. At 8400 you should see 75 easy. I can't comment on the Worx grate as most of us run R&D grate and have minor cavitation vs.the stock grate.

    Ok sweet. What I might do first is install a ss wearing and r&b pump seal in and see if that eliminates my problem ( fingers crossed) if that works I'll get one of those props u mentioned and might also swap out the intake grate with either a riva or r&d intake grate.

    Thanks for helping me out with some info guys. I'll let you know how I go!!

    You are starting to push the stock valve train @ 8400 and if your only seeing max 8550 when limiters are cutting in it sounds like you could be close to the limiter @ 8400. Find out from DCC what the limiters are and what the target prop speed is meant to be.

    A prop change on the T3 brings a huge speed increase at the same RPM, so put that high on your list if you want to see 75mph.
