Your size and weight have a lot to do with how a ski gets on plane. A RN or SXI Pro hull are not going to feel anything like an SXR with a guy your size jumping on it, so it's not necessarily a question of power, because we all know you can make power with a 701, 750 or 800 engine. The SXR hull is wider, heavier and has a much larger tray. I raced the SXI Pro hull for a few years and can tell you that once I got on an SXR hull, I felt like I was cheating! The fact that you ride a 550 hull, tells me that you could probably ride any hull proficiently. Maybe you just need to ride a few more skis, that's the best way to make a decision. Good luck man, sometimes it's fun figuring out what you want by trying different setups.

Exactly. Cornering my 550 I have to fight it to keep it sticking in the corner without washing out on me. That sxr I was laying my hip in the corner and it never felt like it was going to slid out on me or anything. It was like it was suck to the water. But yea I wish I knew someone with a stock superjet I could try. I've been on a superjet but it was modded like crazy I'm talking b pipe, head, dual novi carbs, tubbies, just a bunch of stuff so of corse that was impressive . I want to try a stock for bases of comparison.

Get you a 08+ SJ.. unless you want to do straight freestyle then get the pre 08 Hull
550's slide out really easy, basically any hull will offer a cornering improvement. From the sound of it your sxi pro hull with the 701 is a great starting point. You've already put a bunch of really cool custom work into it and later down the road you'd always be able to move that driveline into a different hull if you find you like something else.
Yea I can't wait to finish my build. But I love your build. I would love to learn how to do resin infusion. Build my own hull that would be fun. But one project at a time I guess. Lol. Already have my pro build and my iroc Camaro is in the middle of a 6.0L LS swap.
And kids arnt cheap lol.

AHAHAA!! That was great!! Yamaha superjet... F the world...
Yamaha superjet!!!!! Ftw!!!!!!
I ride a Sxr pretty built motor blah blah blah . Yea it has power yeah it's fun to carve and all that rides like a dream but if ur trying to do any freestyle a stock Sxr hull weighs a million pounds . It's really a pain in the ass on a beach cart . It's really a pain in the ass anywhere other then in the water . And freestyle really isn't a option . Unless chopped up and a hunch of time and effort . Id say get a rn and piss the motor off thro some holds in it and have a ball . That's if ur trying to fly in the air an all that . If ur trying to race and carve Sxr all the way

I would assume the only debatable topic here is about the engine. The sxr is clearly built for racing. There is nothing to discuss yamaha vs kawi when taking about the Superjet vs the sxr for freeride. The sxr is a tank. Of course the sxr carves well, so does the yamaha fzr, but were talking about freeride. It's going to take a lot more motor to do anything than a Superjet, excluding surf, where momentum and balls are more important than anything.
For the motors, I feel like the yamaha motor hits a lot sooner off idle than the kawi motors, on a stock motor with just bolt ons.

Was wanting peoples opinion of the two. I've never been on a stock superjet. So I was looking for a comparison of power more then a debate I guess.

If you are going to buy it stock, and leave it stock, the Superjet is pretty boring. You can do plenty in the surf, and you can do subs, turn subs, maybe some 180 or nose stabs on the flatwater if you have the skill to do such. A lot can be done using momentum.
I ride bouys with a lot of sxr of various levels of modifications and my Superjet sucked to race when it was stock. It relies too much on momentum and comes out of the water too easy in heavy chop. The pump comes unhooked and cavitates and doesn't have the power to keep going. I'd come it on a piece of chop and come to a near stop when I bashed into the next piece of chop. It also doesn't carve very well.
The stock Superjet prop is aluminum and very large. In needs to be replaced or you can expect a lot of cavitation. You also really need a pipe to wake the motor up. It doesn't carve very well without front and rear sponsons (unless you get an 08+ which carves very well).
With a full limited, set up for rec riding (49mph, a balance between bottom and top in my tuning and prop), I struggle to pass stock sxr, I tire out much sooner than the guys on the sxr and I can't ever get near a pass on a limited sxr (although I can box them out and prevent the pass, but I fatigue much sooner, sxr easier to ride)
For every disadvantage the Superjet has in racing, it makes up for it in versatiliting. I can get 3' or so now off my own setup wake. I can easily double the height the limited SXRs can get, but they are proper strictly for racing so its a bit tough to compare exactly.
If you goal is to cruise and carve whiling staying stock, the sxr is the hands down winner. If you will upgrade a pipe, head, prop, etc, the Superjet wins on versatility.
Another good answer I was looking for. I know the sxr is more race bread and the superjet is more with the surf freestyle. I was more looking for bases of comparison as far as power. Like pulling me out of the water or from a nose stall. Little things like that. You and a couple others have answered that pretty well.

a nose stall??? maybe your thinking a tail stall? the superjet is going to be better for that kind of stuff, especially if its stock vs stock. a stock kawi motor especially 96 & is worthless below 25mph. a stock yamaha motor with a 61x cyl is worthless past 35mph.

Yea sorry I ment tail. My motor is a 61x cylinders and bottom end.

For whatever reason the yamaha driveline provides thrust sooner than the kawi drivelines. That's a good thing. Not that the sxr motor isn't fast. It pulls through much higher rpm...but that's not where we need the power for freeriding. I have not modded my superjet driveline yet other than it has an aftermarket prop, but that came on it when I bought it. Compared to the same year superjet as mine (91) without the prop...it is night and day. Generally speaking most will agree the yamaha driveline keeps its reliability when upgrading to a limited setup. The kawi driveline seems to have a higher chance of failure as things are modded and swapped. Also the yamaha parts are more common and are usually much cheaper.

Got nothing to do with its power. Longer rods does not make it a stroker motor. It is just a different design. The SXR800 engine is actually designed for more bottom end than top. I have ridden plenty of SXRs with Mild to Heavy mods that I would love to put in my Superjet.
