Freestyle Cone vs Bored Nozzle

So I've seen this topic brought up in many threads, but I haven't been able to actually find a thread that compares the two.

One thing I do know is that you do not want to do both of them.

I just put a Skat Swirl 12/17 on my ski and I haven't gotten a chance to ride it, but I am definitely going to ride it before I try a bored nozzle or freestyle cone.

So what does everyone think is a better route to take?

Not the swirl, only with a slimline. The swirl pushes so much more water, I don't think the engine would handle it well.

So you don't think my stock 701 with a bpipe and head is enough to push the 12/17 with a stock cone and nozzle? I figured it would be enough. :dunno:

I think I'm going to have the nozzle bored anyways and stick with the stock cone for now. I'll see if someone can let me borrow there freestyle cone and I'll do a back to back comparison for a limited setup.

Since I have a lathe at my disposal I bored my nozzle back when I only had a head and stock prop. I got my Wet Wold cone when I installed my new prop and stuff last winter and now I have a limited setup with a 85.7mm nozzle and WW cone. concord 13/17 -5mm cutback with no problems.

I have heard that if your reduction nozzle has the veins that you won't have cavation problems but if it aftermarket nozzle you can have cavatation problems... Just what I have heard I have a protec nozzle that has the veins so I can't compare

right!

Ive got a protech nozzle, bored to 87mm I think.

GREAT hit off the bottom, until I added a 12/15 solas concord, then it started to cavitate BAD midrange.

now stock nozzle bored to 85mm, WW cone, and 12/15 impeller, works well ( low pitch for 650 boat)

LPW dude has been saying for a while those nozzles without veins cavitate badly, he is right they DO.

I run a blaster reduction nozzle bored to almost 84mm and a stubby cone from wamiltons w/ a 13/17 concord impeller. I noticed the impeller slipping a little so I went back to the stock cone and it heart me on the low end but it does not slip anymore. I am also running a lamey PV motor. I talked to the guys at impros and they reccomended me cut the impeller back and run a "true" 13/16 pitch. Allot of guys have trouble w/ both a cone and bored nozzle but it is one of those mods that you have to just fiddle with to find what works. I would not bore hte nozzle more than 85mm though

I am getting my skis back 2mor and among the mods are freestyle cone from wamiltons and nozzle bore 85mm.....Ive done to much just to notice those 2 mods.....but both you can do with the right impeller as already stated(for what use you looking for?)

I'm runnin an fs cone, and a stock yami aluminum nozzle bored out to 84 or 5 mm. the impeller is like a 12/15.

squarenose ported650, coffman pipe, 140psi (real safe) I'm not spinning out of the hole yet, but it gets to top speed pretty quick and just flattens out (42mph) :(

If i run an AAT on there, I gain about .8 top end and it seems to pull harder in the midrange, but low end isn't as crisp.

mebbee I should get some compression eh?

fly, with the setup you are running now, you can prolly do both and gain a noticeable improvement in low end and midrange, but you will prolly lose a mile an hour or so off the top. if you start building more motor, then the cone and nozzle might make it cav off the bottom, but that just means its time for a bigger prop:)
