    Quick question about impeller and jet pump on 99 slth

    hey was wondering if the whole jet pump assembly from a slt750 will also work on a 99 slth ski?? I believe it would but just wondering if anyone knows for sure if it will.

    Are the bilge siphon connections the same number on both models?
    Possible differences between reverse buckets and cables, trim?

    The 1999 SLTH was rated at 95HP, and the stock 148mm impeller was 5131457 (12-17 Swirl).
    Was this an extended length pump?

    The SLT 750 ('94 or '95 only) was rated for 80HP and used a 4 blade 148mm progressive impeller - not sure of the effective pitch.

    My guess is that the stock 750 SLT impeller will be under pitched for the SLTH engine, and the engine will over-rev into the limiter at WOT.

    the impeller was replaced on the jet pump..it is an aftermarket solas impeller.

    The pump parts are interchangeable.

    SLTH should have the extended pump, where the SLT does not.

    Do you have any parts of the SLTH pump available to you?
    Especially the impeller and extension ring.
