    How many blades on factory slt 780 impeller?

    I have two 97 slt780's and one has a three blade and one has a four blade impeller.

    I think they had four blades from the factory, does anyone know what aftermarket impellers have three blades?

    Stock was 4 blades. Three blades could be a number of kinds, Polaris OEM, Skat, NuJet and Solas.

    My friend has 4 96/97 SLT780's. All had the 5131371 Polaris impeller,it is a 3 blade 15/20 pitch-looks kinda dull,but not dark.Our impeller chart (tech section) claims the SLX780 uses the 5131371 impeller.
    The 96-97 SL 780 uses the 4 blade 5131079.
    Post a picture of the impeller/part number,someone should be able to identify it.
