really it look more like a over size dremel tool.....found the tool at harbor freight...and it work pretty good.the bigger one was almost the same size as when the nozzle was stock...

I did a pair a couple weeks ago with my cordless drill and a flapper wheel. Took about 45 mins each. Your method looks much easier, was it any faster?

We were going to bore my X2 nozzle with a hone tool. X2 nozzles are plastic. We also didn't end up trying it.

it was easy the 36 grit chew up the aluminum pretty quick and when i got to 84.5mm i when and used the 80 grit to cut down to 84.97mm then the 120 to 85.22mm to smooth it out the nozzle...what was cool too,the tool is the same width as the nozzle where we need to bore out.. it took about 2hrs for me too figure out where to find the tool then to figure out where to start...but the bore part took about 45mins too..if i have too bore out another nozzle it should be less time now that i have the tool and the know how...

Cool, now that you got it all figured out I can bring my nozzle over for a bore job! :)

I have found problems with a wetwolf cone combined with a large nozzle.

Unless you are ridiculously overpropped it will just cavitate.

I pick one or the other to use as a tuning tool to get a prop where I want it.

Just my experience though.

Look at his pictures, he is ridiculously overpropped. Boring the nozzle to 85mm will make a big difference for him. Stubby cones may have some benefit with larger nozzles (havent tested yet) but are a complete waste with stock sizes.

i could say it's been tested already my main superjet has the same set up and that when i had a stock prop,the only different is the cone,it maybe a blowsion cone idk...,however if my main ski didn't have that set up i wouldn't have done this mod,till i had rode one.all i can say this mod will give your ski alot of low end brapppp..

I tried a stock 08 SJ big hub prop with a stock pump. 85mm nozzle and wetwolf cone and the ski went nowhere. Slipped like a mofo.

I left the wetwolf cone on and went back to a stock dimaeter nozzle and the ski hooks up perfect.

This was with a 62T/61X motor ported cylinder, ada head with 33cc domes, dual 44's, msd enhancer, boyeson reeds, stuffers, and R&D intake manifold.

I cleaned up the casting on the pump stator as well, but didn't go that crazy. Just smoothed everything out.
