87MM drop nozzle give up top speed for holeshot?
from my post i like the"low end" an 87mm skat trak nozzle with the 13/19 r 155, would this give me more bottom thrust than the stock 85mm ?

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.

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

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
