    3 blade vs 4 blade...

    ....impellers.

    Blade count aside, are there any appreciable differences in performance?

    3 Blade - Better out of the hole
    4 Blade - Better top end

    Jay are you sure about that??? I have just the opposite: 4 blade, tweaked stocker very quick out of the hole, no cavatation.
    3 blade, less hole shot and will cavatate alittle if you hammer it right of idle, but better top speed...What do ya think?...PR...

    Andy,

    This is from my personal experience of running a Solas 15/20 compared to a Skat 3 Blade 14/19.....So, yes, more top end with the Solas and better hole shot with the Skat.. Ya wanna buy a Skat 3 blade???? I am all about the top end and it's for sale, and only run once....

    a 3 blade, when properly tweaked will out perform any 4 blade from bottom to top.

    I've had nothing but great results with the 15/20 Andy and yes I am running the RXT drive shaft as well. Maybe there is some life in the 3 blade but I don't think it is in the form of a 14/19 with my setup.
