Good Day,

I have a 2008 Kawasaki ULTRA 250X with 92Hours,

When riding it, I get a very loud whining noise instantly when I accelerate, this noise only appears when I am in the water because when I flush the ski on the trailer there is no noise,

I checked the following:
  • Supercharger Belt, stiff and tight and still has good grooves;
  • Supercharger Oil, seemed to have very little oil, around half the mark and the oil was very tick kinda sluggish;
I have ordered the following to replace:
  • New Supercharger Oil from Kawiperformace
  • New Pumb bearings to replace the old ones, not yet upgrading to the 300X pump kit;
What could be the reason for this noise, the more you rev the higher the noise,
Also note that this ski had been stopped for almost a year at a 2nd Hand dealer,

All Assistance and ideas are welcome,

Thanks & Best Regards,
