So do the cylinder, pistons, heads from a 701 swap directly onto the 650?
Buying Older Skis, need advice

@KMN Thanks for that, yeah anything I get at this point whether it be a project that I build out and make nice again or a good running ski that I keep in good running condition I plan to keep for a very long time as well.
@Pro-pulsion that's good to know about the kawi and yamaha parts, I hadn't given that aspect much thought

Don't buy a "project" ski. Buy a ski which is nearly as stock as possible.
As @Big Kahuna says: "That SN is mint."
Quit dinking around and offer the seller $2800 for it especially with the stand and go get it.
@kevbo knows allot more than me, but the premix oil in that 650 has "fogged" the crank already and there should be no rust because quite friggin' clearly that ski has been stored indoors. And the original 1990's tray material is not even frickin' worn.
Dude, you are a fool not to scoop it up immediately, even at full price $3000.

Step 1, buy this ski. Step 2, find another. Avoid project skis for now, it wont be worth the headache. Finding parts for these SJ's is a walk in the park since they are so interchangeable and have been used on every yamaha ski forever. Step 3 Have fun!

Project skis got a lot more people out of standups than they ever go in , listen to these guys .
Yes but with some machine work. The crank is the only part worth keeping provided it has no corrosion. A perfect crank is worth $1000. Otherwise the 650 engine has no performance value.

The 701 intake setup is vastly superior to the one on a 650 , they look similar but perform QUITE differently , as Kevbo said the cases have to be enlarged to clear the sleeves on a 701 cylinder , my advice look for a Waverunner lll with a 701 61X in it , pull the 701 out and put it in the Superjet , put the 650 back in the Waverunner and sell it , in that ski it basically runs no different , Waverunner lll's are cheap and at the start of the season pretty they are easy to sell and get rid of.
I did a swap for a customer almost just like this a few years back ,only difference is it was a Waverunner VXR pro donor ski SKI which has way more Superjet compatible parts on it, jet pumps , intake grates , ride plates, midshafts and housings all the same as a SN Superjet . The driveshaft is a different length though .

Just run it as a 650 for now. The 650 is not anemic. I put a 701 from a Waverunner into a Square Nose and, yes, it is slightly more powerful and I am glad I did it. But the 650 was fine for starters.
You CANNOT compare a SN SJ 650 with a Kawasaki 550sx. The 650 SN SJ is much more ski. Even in stock form it has much more bottom end torque than a 550sx and the SN has a more refined hull and pump and steering design.

I did just pick up a 94 wave raider 701 for dirt cheap figuring I'd probably be able to put the 701 in it to good use at some point. I haven't looked into it at all yet but it does have an electrical issue, engine turns over with no spark. If I were to swap a 701 for a 650 would I need to swap all the electrical as well or do these work as just a straight engine swap? Also, I'm not totally clear on the differences between the 61x and 62t. My understanding is single carb vs dual carb and the 61x has better bottom end vs the 62t better top end performance, is that correct?
I'm with ya there, if I end up picking up that 650 SN and it runs good as is I'd probably want to just leave it stock at least for a good while

You need the 60T CDI to go with the 62t stator , the Superjet engine is pretty much a 62T twin carb engine with a 61X single carb top end on it .
@WFO Speedracer alright thanks for that info

Old skis are cool buy em
If you're not so mechanically inclined
I would definitely as others have said.
Buy the cleanest thing you can.
Frankly the only way they aren't a depressing pit of sludge and faded. Means someone had to care for it, mostly indoors it's entire 20-30yr life. Typically a good sign.
not the route I'd go but anything mechanical you can just throw money at. SBT sells new motors everyday of the week, plenty of companies around who do turn around carb rebuilds. Rest is just kinda parts slapping. Read the manual.
A clean hull without breaks, or water intrusion is what you need to be pursuing

i think i may have gone over the top with my js 550 but im glad i did. if i have any piece of advise its that if you head works like mine, i like to make sure everything is done right. that means when i know i have a project i go through it all. i touched every single piece of component on that ski.
basically if i buy a ski, i want to know exactly how much its gonna cost for replacement parts {crankshafts, cylinders, electronic, props, ect) if NEW or refurbished parts are even available for this ski. what im starting to realize is that the old skis are cool but finding people who make parts like a stator for an old js 550 virtually don't exists. that means if i start having issues with it im gonna have to pillage another ski for 1 part.
yamahas are really the way to go. for the most part if your looking to keep your ski running people are selling good/new OEM parts for almost every engine they ever made at reasonable prices.
but their is always something really cool about someone showing up to the beach with a relatively OEM js 550.
also my dad bought his fx1 new from yamaha in 94 for like 5 grand.
they are selling for close to 6 or 7 now.
the way of the world i guess.
