    Well, this are the same speed (71 to 72 MPH) that (ALL) the stage II RXP'S from my riding area are doing in our local heat soak and high humidity weather.

    In another note, my moded 05' RXT was 3 to 4 MPH SLOWER from the speed that Riva advertise in their stage II race package, but this was in the past NOT anymore since i put a aftermarket prop that is doing wonders in my ski with differents spec's than the one they recommend for their RXT stage II kits.

    yea Ray, what climate are you in again?

    There are many, many stage 2's north of you running 75+. Brendan even runs 77+ with his.

    Jerry, i am talking about mid 80 to over 90 deg and very high 70% to 80% humidity, just look at what happened to Jarrett stage II RXP after the heat arrived to his riding area in Texas, he lost between 200 to 250 peak rpm's and 2 to 3 MPH in the top end just from the heat, this are exactly the same weather conditions that we have to deal (ALL YEAR ROUND) in our Island located in the caribbean, in fact one of the fastest stage II RXP from my riding area is the one from my friend (Israel Padilla) and this ski best top end speed numbers are 72 to 72.5 MPH spinning a (out of the box) 14/19R solas prop @ 8400 peak rpm's with the help of a R/R first generation race ECU, but of course there are some rare exeptions since my local pwc tech told me that he built a stage II RXP for a customer that is doing between 74 to 75 MPH (Gps) with only bolt-ons with the help of a second generation R/R ECU, a different size exit nozzle and a custom blueprinted solas prop made for him by Dave from Impros.

    Ray - I ran 77+ on my Stg II with 80 degree temps and mid 70 degree water. 100% humidity! The water was glass though.

    Ray: I ran a 15/20 @ 8100 stock ecu . Now with the "B", I'm in the process of adding more pitch.
