So I just finished up a SN Superjet for someone. This piece was laying in the hull when I started working on it. Found where it goes on the schematic but still don’t understand where it goes or does. Anyone have a thought on this

Well I figured it out the other day. I popped out the fuel tank and pulled off the hose. Payed attention to it and the one side was different than the other. Exhaust side has more of a squared off curve into the exhaust where the other side is more of a natural curve into the waterbox. So I had...

Like your thinking

Yeah my 08 SJ waterbox is definitely bigger than the fiberglass stocker that’s in this ski. So all 701 stuff is 2.25”. I’ll measure the waterbox inlet and the muffler exit next time I’m at the ski. When I say the hose was extra big to attaching to the exhaust piece it was lime throwing a hotdog...

Working on 93 SN Superjet for someone. It had a 61x motor swap into it to replace the original 650. I pulled the engine out to replace the mounts, midshaft, pull tank n clean. Well I fixed everything up n really the last thing I had to do was hook up the exhaust tube from waterbox to the stock...

Thanks for the reply. Ok, figured buying the sxr harness and ecu would be best. Never really thought about the intake. Never really paid attention that the stx n sxr were different. Gonna have to look at some engine bay pics now, lol.

so, I’ve never really thought about this but when your doing a race hull with the Kawi 1500 engine, what harness and electronics are you guys using? I get if your pulling the engine out of a sxr1500 it’s pretty cut and dry but what about the stx models? Bc they have a gauge and probably longer...

I have one of these. It works great. I use it to check my bike and trailer tires all the time. Worked pretty good to blow up some pool toys too.

Reg numbers are Ohio. Guessing that’s were the ski is at?

Nice countach in the back. Never seen that blue before

I think Stevie wonder saw that coming. If he had made it completely around, there’s no way it would have made it through unscathed. Definitely would have been in the carnage section

Very good idea on using the carbon seal transfer. I have a 2011 ultra 300x that I’m in the middle of putting back together. It ran but the inside was just a mess. Pulled engine out to clean and repaint, clean intercooler (was packed up pretty good with dried salt), repair the oil cooler bc a...

Found this one on south jersey craigslist. Guess you inspired someone

That should be an awesome ride. The stx hull is great. Yes a little wet compared to the ultra but it tracks really good. Just make sure the metal plate that gets glued down were the drive shaft cones through also get screwed down. I guess that means if your using that method. I would personally...

Wow, I didn’t it was that much HP. I guess it would be worth to fix one straight then. I’ve ridden some of the older Polaris sit downs and they were no slouch in their times. I guess the octane would be no different

I went back yesterday and it was gone. I didn’t notice that it was almost up. Last I saw it was at $1050.00

Wonder if the factory pipe that it comes with is the same as the one on the SJ?

Cool, I’ll have to keep an eye on this bid. It’s in MO. Might not be worth it for myself after all the shipping and buyers fees. Think it’s just over $1k already

Yeah it’s definitely a Polaris engine. Have a Superjet currently. I know they had some decent success in the racing area with it. Just wondering if anyone has done any conversions in it? I have a spare 61x/701 that needs a trans plant.

Was on copart and saw a Polaris octane ski for sale. Head was taken off and it said it wasn’t running. What are some options for this ski? Is there any Yamaha conversions for it. If so, Engine only or pump too? I know anything is possible with some creativity.
