    Impeller for STX 15F

    Which impeller will give the most speed gain for the 15F?

    solas 14/20 - maybe rebent to a 14/21 if your 15F can pull it.

    if u are going for the all around bottom, mid, top thing...then get the impros stage 1 solas concord prop, hands down best prop imho

    if you just want top end, go with an untouched solas 14/21 concord

    Stupid question... Are the 250's and 15f's interchangeable with each other? Same size? I don't know the 15F specs.

    NO

    15f is a 148mm pump
    250 is a 155mm pump

    the prop pitches are way different either way

    This is my buddies ski. It is stock right now, but he ordered the free flow exhaust and will be getting the R&D Ride Plate. He is just trying to keep up with my Ultra 250 or at least get it so that he can stay reasonably close. His stock 15F does 60 gps. I do 70 gps. I'm getting tired of waiting around lol. Just kidding. I see that some of you guys are flying on the 15F's. What a great deal they are now! He got it for $7299 plus tax title and licensing. Can't beat that!
