    15/20 or three blade?

    Ok, here is my situation. I have an 06 RXP with 25 hrs and the following mods:
    Riva Stage I with wedge, Riva Rear Air kit, RE blockoffs and thru hull exhaust installed.
    With the above setup I am right at the limiter running 8160-80 and can hit 8200 at two clicks above mid on the trim.
    I have an XS IC on the way and skegs sitting in the garage which will be added soon(this week?)
    Which prop will be the best for this setup and not end up putting me back on the limiter when I add a SC impeller(Stage 3 Riva SC or RR high boost) a month or so down the road?
    I do not plan to change ECUs or get into the valve train. The only other options I am considering are the adjustable nozzle, 42# injectors and of course the metal washers(Will send SC to Jerry when the SC wheel decision is made)

    Thanks for the help in advance!

    Considering your future mods and black tubes , get the 3 blade. You will need to tweak either prop to get max performance. The 3 blade has more upside..

    I would shoot for 8200 rpm as a goal for peak rpm. I have an 06 & I was seeing 8280 rpm & if I backed down to 8200 & then pulled full throttle the ski had good power up to 8280. Wether or not my ski has a "special" stock ecu or not I don't know.
    a tweaked skat 13/18 or 15/19r would be the ticket.

    if they all have the same rev limits, then i guess certain years have some awfully inaccurate gauges and screwed up electronics
