rxtx 2009 cavitation - tips/help
looking for some suggestions/tips
My mate has a rxtx 2009 - 15 hours
just added the following
a kit x (les cooke drop in wheel)
reflash ecu to 8400 rpm
new wear ring
new skat 3 blade 14/18 prop.
prior to additions ski was running great however since the mods , i have cavitation issues on take off...this occurred the first ride after the mods ... i knew i didnt suck up anything but, i ve checked both the prop and wear ring and no signs of damage
ski is fine after i take of, revs sit perfect, floats between 8280 - to 8340 max depending on conditions..
hope you can help as it feels any gains i had by upgrading are being lost on poor take off..
Although only low hours , i ve checked carbon seal (no water getting into hull)
any other clues??
im assuming prop set up as this is the newest addition ??

Bellows and ring are weak. Change them out and get a bellow band. Makes all the difference. The upgrades will how the weakness of it. You are pulling air from within the hull. That prop has a much steeper root angle and has more 'pull' and thrust than the OEM prop. Make sense?

The first mod for any 2008/2009 RXT-X....pump tunnel reinforcement & a bilge pump.
Next, check the alignment of the pumpshoe/driveshaft at the thru the hull fitting......if its off center then the carbon seal/floating ring/bellows could be sucking air.
Last, the large rubber seal around the pump could be twisted and not sealing properly.
