I Have A 1999 Sea Doo GSXL that I just replaced stock pump with a used 148 Skat Trak magnum pump, I need help choosing a impeller, It now has a super slim line 13-24 that cavitates out of the hole pretty bad, nice cavitation burns! Wear ring and bearings are new. I was thinking a Skat d-75 swirl or Solas Concord .Thanks for any info>
