On my 1997 Challenger model 5603 787, Who has replaced their impeller and what degree did you use? I am in salt water and know that if you are in salt that the degree is 1/2 degree less than fresh water. I remember the difference from the days of racing Kawasaki's stand-up ski's. I looked on Solas web site, but it didn't give much in detail as far as degree or availability and Skat Trak seems to be non exsistance... any Help would be super! My stock seadoo # is 204 160 027 they offer only this # for an impeller for this appliciation in my parts book.
