Compression test.
If you get the 2014 sj there is an adapter you can add to the steering nozzle that makes it ride more like the 96-07 skis.
650sx vs 2014 Superjet what can I expect?

How would I perform a compression test? Sorry for the newbie questions.

Unscrew spark plugs ,. lay the plugs on the head with spark plug wires attached, screw in compression tester into the spark plug holes, hold throttle wide open and spin it over till the gauge gives it's highest reading, repeat for the other cylinder, if you don't want to buy a compression tester most parts stores will rent you one.

Idk. I've had a idiot show up to buy a ski from me and his hf gauge read 90 psi and he told me my ski was crap. Even though it literally ran right in front of him. That was 4 years ago. Same engine I'd STILL running to this day un touched. So don't take compression readings too seriously
If it runs and sounds crisp. Its fine. If you start listening to a bunch of people who spend more time broken down with a hood up, then riding, your gonna end up hating this sport.
Make him take it to the water so uou can ride it. Anyone that trusts their ski would have absolutely no problem with that. A compression test doesn't mean dick if the pump seal is blown. Or the hull leaks. Or the cables all need replaced

Makes sense, I was thinking the same thing... a water test is an absolute must. It's no deal without one. Cheers.

So (assuming) you haven’t ridden a ski since 06’ and have never ridden a 14’ superjet before.. do you think you’ll be able to trust yourself 100% on determining the mechanical condition of every part of the ski by simply riding it?
I’m not saying water testing isn’t a good idea but why would you NOT want to test compression with a verified gauge too?
Major compression issues of course are easy to identify but you’ll be able to get a feeling on the condition/hours of the engine with a simple 2 minute test.
Valuable information to pass up on because of “idk”.
Compression gauges are a extremely valuable tool to have on hand and you will want one in your tool box regardless of if you use it for this purchase or not.
Personally I would want to know the condition of one of the most expensive components of the ski before I spend a few g’s. But be careful listening to me… I could be one of THOSE guys that learns by troubleshooting and wrenching instead of learning telepathically via riding the ski !

Because dropping a shot glass of oil into a cylinder will bring the compression from 100, to 150. And a newb isn't going to know how to tell that.
What does it matter what the compression is, if the ski rides and runs good? Is he going to be held back from a 10 or 20 psi loss? Is it going to explode the first ride if it's low? No. It's not going to matter at all unless dude is at the peak skill level and being held back. Even then. It's always just new rings if it's tired and hasn't been seized. It's not a bargaining tool.
These engines don't just explode. It's actually really HARD to blow one up. I used to try. I'd log roll and hold the ski pinned bouncing off the limiter, and then hook that pump up like it was on a drag strip. Over. And over. And over. Never had a seizure. Never wore one out.
I know guys who profess their knowledge online. But constantly have issues with their skis. They ride maybe 1 time a week and spend the rest tinkering and telling others how to do it all. Don't be that guy.

Ok so you would be indifferent between a engine with 120psi a hole and one with 150?
You wouldn’t think to yourself “hmmm maybe the motor with 120psi has more time on all its components.”
A “newbie” has to learn to not be a newbie anymore lol.
A shot of oil can be cleared out within seconds with the plugs out.
If a newbie can’t do that he can’t do a top end then right?
Your average person doesn’t profess anything, they offer their advice.
Arrogant pecker heads claim their word is fact and act like a king amongst peons.
You were just saying the 6m6 was easy to work on and that you need to work on stuff to learn… which I agree with.. so why Gate keep the guy?
Sometimes to become the guy that can ride non stop you have to be the guy that wrenches on your mistakes.
We both know in high power motor sports things will break lol. Some people may have setups that take more abuse but in the end stuff can only get thrashed so hard before it takes a vacation.
This is the number one problem with old jetskis. Its not the hours of run time that ever kills them, its always an ignorant or careless owner. The fist thing Ive noticed is very few people blow all the water out of the exhaust and store the ski properly. Ive seen skis completely ruined after one season and 10 hours of use. Then there's modifications, almost everyone turns up their rev limit too high. They widen their exhaust port too much and crank up the compression and ignition timing and run cheap gas. Any time you buy a used ski make sure you have an additional $1500 to catch up its neglected maintenance. Kids want everything right now so they run up the prices on skis that are little more than garbage bins.

Personally I have a lot of questions on that ski, what's holding the water lines on, I don't see a single clamp anywhere, why are there wires un-pluged on top of the fuel tank, it's running crappy fuel hose the goes bad after a year or two, I can't really tell from the pic but it looks like some of the head bolts are just regular steel instead of stock or stainless. steel, that flame arrestor is crap those unglue and come apart., missing at least one engine mounting bolt on right rear corner, want me to continue, personally I would run.
Nope, I am gone. I so appreciate the expertise on this forum
Thanks, but trying to find one closer to me in Ontario Canada

Yep whoever buys that will be doing a lot more wrenching than riding.

Ontario to Minnesota is nothing but a fun road trip for a good ski.
I bought my FX-1 in Minnesota and I live in California.
20-27 year old skis in good condition are hard to find. And when you find one, it may be in an inconvenient location.
