15F exit/steering nozzle size
I was looking over the pump on my 15F, the exit nozzle is 82mm across & the steering nozzle is 92mm. From what I have read on this site the general rule seems there should only be about 5-7 mm difference, the ski performs well, but could there be any advantage in using a steering nozzle closer in size, I do have a 88mm steering nozzle & a 80mm exit nozzle too. I have noticed this ski does lose more speed in sweeping turns than I think it should, could tightening up will a smaller steering nozzle concetrate the thrust a little more? Not sure if anymore testing will be done this year, too cold now, otherwise I would just try it.

Interesting thought, keep us posted.

Ok, we have a warm day here, so I tried out the nozzles. The smaller steering nozzle made the steering very tight, my rotator cuffs would not be happy driving like this all day. I does turn sharper & the speed loss in turns is slightly less, other than that no performance gain. The 80mm exit nozzle, did take any holeshot cavatation away, but dropped the rpms too low & made for a poor holeshot, top speed was about the same, within a couple tenths slower. So Kawasaki has figured out the right combo from the start.
