    reduction nozzle/impeller pitch

    i am scratching my head on this trying to figure it out.... if we have the correct impeller pitch to match the hp our skis are making we should have no need for a reduction nozzle to acheive proper rpm at max speed?

    But rpm's will rise and fall with air and water temp. changes plus if you add mods etc. Changing the nozzle will allow you to tune the ski for varying conditions without owning a bunch of impellors or going to the trouble to pull the prop and repitch. It's a pain in the azz to pull the prop in my opinion unless you really need to make a pitch change. My ski started out running 8120 last week and 2 hours later was running 8060, probably from heat soaking.
