    Polaris stock impeller for the 1997 SL1050 was 5131366, 17-23 Swirl

    Same 17-23 pitch 5131366 impeller was used for the the 1996-1997 SLTX, and the 2000-2002 Genesis (don't know about 2003-2004 Genesis)

    Hey morg-welcome to my HELL. I have the same issues with my 97 1050.I can not understand why it is that way(total lack of accurate informatition),I have really tried to figure it out with no luck.I'm more interested in top speed,I found the NU-JET 7.0 works the best for all round performance and top speeed.It seems the factory impeller is rather special,but hard to find.

    I talked to a guy with a 99 1050 a while ago and he really liked a Skat Trak 13/23 or 13/24(if I remmeber correctly,which does not happen often)Very good hole shot,decent top speed.I guees it's a matter of preference.

    The 97 1050 DOES NOT use the same impeller as the 98-99 due to different running rpm. The 97 turns more RPM and makes more HP. It needs a slightly shallower impeller. Nujet 6.5 is what I'd use...more speed and top end acceleration than the Skat, with slightly worse take off. I found the 7.0 on my 97 1050 to give a tiny bit more top end, but made the acceleration worse and the ski felt a little doggy...but mine also had higher cylinder port timing.
