Just wanted to give an update on this problem. I removed my manifold and replaced all my gaskets from the head all the way down to the stringer. I went for a ride assuming it would be fixed and it...

In case someone is in the same situation. I switched to the newer FZ nozzle that’s 85mm and it has virtually eliminated the sensation that I was experiencing. The hole shot is waaay better and the...

awesome! I’ll be buying one as well.

That’s awesome. I hope it is more durable than current clutch. I have 30 plus hours on mine and it’s still holding!

Ok. Thanks man! Ill leave my prop as is then and I should see 9400 ish rpm.

perfect. Thanks for that. I ordered a 2016 fzr nozzle so its 85mm 3 degree. I wonder how much that will raise my rpm if it don’t touch the prop? My current nozzle is 83mm. What are the factory specs...

Can anyone confirm the size of the fz Venturi nozzle diameter? I have the extended smaller nozzle from Dean now which is 83mm I believe. Im wondering if I can keep
my pitch the same without hurting...

thank you. Yea, always careful it is dangerous-this ski isn’t for a rookie rider. You can get into trouble real fast...

Exactly I remember when I experience at first I didn’t know what it was but now that I know, I’m sure of what it is.

im with you on the incremental adjustments. I think I have the power to turn a 13/20 to 9200 with a open nozzle. I guess I just have to try the fz nozzle first and see where my RPMs are. My bet is...

I don’t have a stock prop nor stock Venturi but I do
have a stock fz Venturi on the way. I don’t know if i
should throw stock nozzle on and keep prop and see what my RPMs are, or send out to dean...

ok. Haven’t ever heard of anyone using a 12/17. Let’s let some
prop gurus like jim chime in. I already ordered a Fz nozzle. I will order a new prop when I know what i should get as far as pitch.

Thank you for that informative reply. It makes complete sense that low separation. Between leading and trailing should be kept at certain difference for maximum pump efficiency. I am wondering, what...

ok. 82-83mm inner diameter?

understood, however wouldn’t changing the prop to a 13/18 drastically decrease my RPMs without switching to the FZ nozzle?

ill give that a try. Thanks for the input. Shall I get the L13 as well or no?

ok. Thanks for the input. So a stock nozzle bored out 2mm is the way to go? Along with a 13/18 pitch + L13 cone? Correct me if im
wrong but, will I have to remove the Syphin in the nozzle when...

yea, it’s a 13/18 de-pitched to a 13/16 to keep RPMs up given the extended smaller nozzle. Only problem is with L13 I would rid of the stock Bilge syphin.

I believe it is what you described. However i sealed it Better than what the factory did. I would’ve hoped this would’ve eliminated it. I wish somebody could give me a tutorial on exactly where to...

I suppose it can be that bit it still feels slower out of hole given a certain throtte
input. If it felt the same as it did once in plane, then I would say it’s just resonation from exhaust and I...

2019 Fx svho, modded grate, Solas prop13/16, extended Venturi smaller diameter, transom resealed.

Been driving me nuts and need to know if it’s normal. Upon getting on plane the ski feels like pump is not efficient and it revs but doesn’t accelerate as fast as you would expect given the amount of...

I did have the oem plate cut by him first. But It would bounce at high speeds.

Sure. That makes sense. Well, I’m not sure I want to tinker with it more as it is running great now. If I had a stock nozzle, my RPMs would probably be 9800 and I wouldn’t be going faster. With the...

You have more power? What size wheel and do you have na cams as well?
