Thread: Nozzle question
06-29-2007, 07:45 AM #1
I've read all the thoughts on 85mm vs 87mm on a 1300, but what about on a stock 1200? Any one better over the other?

My ski is a 2002 1200 gpr BB, I use the stock pump with a concord, I am doing very well on top speed, I have measured my nozzle cone a couple of times. It is 86 mm. I have even sanded it to make sure there is no burr. it seams to be still 86mm. I tried a 85 mm and gained .1 mph but hole shot SUCKED. I hope this was what you was asking?

In my experience its been more about target RPMs and getting the motor there. Just because one nozzle is faster then the other on a given day doesn't mean its a better nozzle but may have brought you motor into its torque curve. I have pitched props to produce the same rpm with the 87 as it was producing in the 85 and netted almost the same results. I would look at the 2 nozzles as more of a fine tuning part for any given application.
