    Post up your Prop/Pump/Nozzle combo results

    Since we have lots of guys going to reflashed/aftermarket ECU's now, I figured we could use a thread to document what is needed to get these higher HP skis dialed in with a good balance of holeshot/acceleration/top speed. This way our results won't get buried in other threads, making it harder for newcomers to find the info. Please also include what conditions your setup is being used for...ie flat water, CC, offshore enurance etc.

    I'm currently running the C1 with the stock ECU/pump/liner & I have been able to nearly eliminate holeshot cavitation with a 13/24 Skat Swirl, R&D pump cone & 82mm ring. My 15/22 DF with the same setup adds ~2mph on top, but does pop the limiter 4-5 times from a dig.

    I know Jerry has had good results with a 160 liner/8 vein pump on his E1 Motec boat, but I'm interested to hear from others who are running the C1, B1, C3, E1 & ET wheels with other levels of supporting mods. Post away gentlemen.

    Still on a stock pump, E1 Wheel, 13/25 skat and stock nozzle installed.
    Good for 82mph with cavitation of course a few months back.

    Help a brotha out. Where are the corresponding impellers? Think this will be a good alternative to an $1800 dollar pump that us lower power guys might not need?

    I think you have to send your prop off to have material added to fit the liner. I can tell you that with stock ECU and B1, cooler, boost bypass, etc and a skat prop (especially with a big # on the leading edge) the acceleration is pretty strong and cav wasnt too bad. Seems like early reports are saying the reflash adds considerable cav because of the advanced timing. Duke said the 160 liner works very well and it just may do the job for a ski with a C3/B1 and reflash. Even if there is still cavitation it may solve the problem enough to not warrant dropping another $1500 or so. That's kinda been the whole goal with Bobs ski is to give the ski as much power as possible without having to spend so much on supporting mods like pumps/props and additional fueling.

    In the store. Start bending.
    13/23 here:

    Something to ponder.
    liner - $238.00
    impeller $329.00

    So, with $567.00 for those parts with the remaining $1,200 for the pump doesn't seem so terrible for a custom pump then. All relative.
