How to improve holeshot?
With higher hp how is everyone ensuring a solid holeshot every time?
From a dead stop or even a holding start my ski fights its way out of the hole (cavitation), after say 10 metres its all sweet.
At the moment I'm running a c kit sc, xs ic, 4 inch air intake with a 14/19 skat 3 blade, worx grate and other bits and pieces. In the next couple of weeks i'm reprogramming my ecu to 8600 and adding black magic headers and a shorty gibson. I know my prop probably isn't right for this setup but I'm sure the same thing will most likely still happen with a 15/19
So in short, with this level of performance what is everyone doing to ensure a good holeshot?
Or is it trial and error, each ski is different?
Any help or input would be sweet

Change to a B kit(0
The C kit is for top-end, Low and mid range is where you need the grunt, not top end.
BTW, did you lighten the valve train parts?

To cure the cavitation on take off I am thinking rotax pumps on both skis or try a pump extension kit. Anyone had any luck with any of these on there 2rude charged boats?

I would look at 1 of the available pump seals, they will cure alot of cavitation issues, coz with big hp the carbon seal can suck air into the tunnel under a hared accel. Also you may need to have some pitch put into the leading edge of your prop. I found that my top RPM was about right but I had big cavitation out of the hole so I had it pitched to 13 on leading edge and the issue went away. What prop are you running 3 or 4 blade?? R88
