Educated Guess Anyone?
As my avatar shows...I have a 05 Seadoo Challenger 180 215 SCIC Sportboat. I just recieved my shop manual and lo and behold it has the pitch angles listed for my boat. I have been after my dealer to find this tid bit of info for ages. Anyways, stock impeller is 11/21.
I pulled the pump and I have normal wear ring wear with 30hrs but will be replacing with a new stock one or Skat SS wear ring.
Now to my question...I'm installing external intercooler, thru-hull, 4" intake w/flowrite that gets 100% fresh air and RR S/C impeller. I understand the RR SC impeller makes more psi and may or may not work with the stock injectors and ecu. If this is the case I will go with Riva Vortech impeller.
Which impeller pitch should I start with?
I currently have:
*cavitation out of the hole (after installing cold intake)
*7650 max rpm
*47.8 mph top speed.
