    You would be maybe 1-2 mph slower on glass but the swirl prop hooks up way better so in any rough it will be good

    its 85. If you go to a 87 it'll improve your holeshot but you will lose RPM's.

    85
    Time and time again we see different results with different sizes. There is no sure fire formula.

    I thught I will loose rpm going from 87mm to 85mm.
    I just ordered a 87mm nozzle from WFO for better holeshot and maybe gain a few rpm's.

    with a larger nozzle, there should be a slight increase in RPM's

    I gained 200 rpm by going from an 85 to an 87mm nozzle this past weekend and dropping the trim from neutral to one click down.

    This is on a pretty much stock 07 boat spinning an impros 14/20
