i'm looking to put a new impeller on a 99 ts640 which has a 14/18 impeller on it. the reference charts for NuJet impellers state that my ski can use a TS-A5.0, a TS-A5.5, or a TS-A6.0. i need to know the actual pitch angles of these impellers so i can select the proper impeller. thanks in advance!!!!

Re: NuJet impeller numbering system????
It doesn't matter what the numbers are, you can't compare them model to model or brand to brand - they are all proprietary pitches. The aftermarket charts will give you choices based on your modifications of the ski (power to push the impeller).
