    Impeller replacement

    I have a 2014 FX SVHO and looking to replace the stock impeller with a Solas impeller 13/18 or 13/20. I have two questions. One, which is better...the 13/18 or 13/20? Second, is it required or wise to replace the impeller housing when I install the new impeller? Thanks all.

    Do you have any mods on the ski?

    If the ski is in stock form and you are looking for more performance I would not recommend an impeller as a start.

    Your best bet is to first get a map tuner and install a stage 1 tune.

    If you still want more then install a 13/18 impeller, Macs Boost air intake, Riva Cooling Upgrade Kit, and stage 1 tune.

    The Solas will help but NOT eliminate cavitation from start. You will also notice better mid range torque. One thing that I was blow away with was how Swiss watch smooth my ski is vs the OEM impeller. I feel ZERO vibration. I didn't think I did before but must have. OEM impeller was in pretty good shape.

    That depends on the modifications/tune on the ski. General rule of thumb is use the 13/20 for 8400 and less RPM and the 13/18 for over 8400 RPM.

    You don't generally have to replace the wear ring unless yours is in bad shape. The GreenHulk Store has everything you need at discounted prices.
