Hi, I have a gtx 1997 and i want to change the impeller because y rebuilt the engine and made modifications to it. I am between two Solas impellers but don't know which one or the pitch i need. I want more speed and acceleration. Normaly when I use my jet ski y to cruse fast or wave jump. i don't normally tow. i am between SD-SC-XI-17-24 and SD-CD-16/24. Thank you
