Right, I wish I could but whomever is selling it, won't return my emails to them. Which makes me think, either they are on vacation or have sold it and haven't removed the ad, or decided not to sell it. Either way, I can't reach them.

Only one question, which engine oil are you guys using?
Thanks for all of your advice along the way.

First, pics or it didn't happen.
Second CONGRATULATIONS!
Third, you are from Ontario, so the same oil company for what you use in your sled of course!
Fourth, a jet ski engine mechanic told us to run 40:1 so that is what I have been doing. You will lose some high rpm but your crank will love you.
Fifth, that Blowsion handlebar bilge switch is worth every penny.
Sixth, you said "high compression," but you didn't say what the compression was. What is the compression? Oil acts allot like Octane, so it can reduce some pinging and like too much octane can reduce high rpm. Most people will tell you that you can run pump gas below 200 psi compression. But my experiments with my 550sx at 184 psi both cylinders I played around with mixing race gas and pump gas and found that I like how the engine sounded best with this:
550sx Octane experiments - Compression both cylinders 184 psi / 184 psi
98.6 seems best - much more rpm at WOT than higher octane. 110 octane Race Gas, 91 octane pump gas 5 gallons total 1 gallon each mixed as follows:
110+110+91+91+91 = 493/5 = 98.6
with Oil 40:1 which is 16 oz to 5 gallons fuel
Seventh, don't forget to ask about primer vs choke...
Finally, I forgot who I stole this from, but it is always appropriate:

I want to believe this... I would order a new XFR right now if this were true, but it just doesn't seem possible. Whats the lengths on that thing with the full rideplate?

I like Klotz, mostly because it smells like heaven, but usually run Amsoil Interceptor, because you can get it from Canadian Tire. Don't put too much thought into the oil and use the search on this forum for questions like that to avoid either getting trolled or causing a massive argument.
Whrere'd you end up finding the ski?

At any rate with 180 compression I would be running some kind of decent oil, not Walmart Stupidtech
I found the ski near Haliburton.
The oil question was more related to it is running Amsoil Dominator now, and on their website it indicated that the oil should only be used for short term use and if your engine was being worked on each year. I will winterize my ski but I am not a mechanic so other than changing plugs etc.,I wouldn’t know how to do much else.
It also indicated to minimize mixing oils so thinking I should run the tank till empty then use a different Oil. In any case going to pick some up to,orrow.
You will have to do some research and find out if your piston gets hot enough for long enough to take advantage of a higher performance or air cooled type of oil. Few standups ever exceed TCW3 temperatures long enough to matter. Plus its corrosion protection is very good. Im a fan of Maxima Super M for high performance watercraft because it has a lot of petroleum in it that is good for corrosion and an aircooled detergent that has never fouled my plugs.
Hey, I noticed that the machine is stalling when idling after a spill in the middle of the lake and takes some coaxing to get going again. Not a big deal but do you have any suggestions?

@canuck Hopefully you can find some value in this post. I understand that much of this post may miss its mark depending on you.
Personally, I ski in the relatively wide main channel of the Sacramento River. When I fall, I am usually riding pretty fast, so I ski with a lanyard on my wrist. When I fall, the lanyard pulls the stop start switch and kills the engine. Your stop start switch may have a zip tie so you can ride it without a lanyard.
I prefer to swim to my ski. I also don't ski alone, so my wife (if she is skiing close by) can pull me to my ski.
Also, I wouldn't focus on your ski's dying after a fall. Rather, I would focus on why your ski won't start immediately after a fall. That requires proper turning, which will require, for now, an experienced 2-STROKE jet ski mechanic. A primer can be a band aid for a lack of proper tuning for now. I use a primer, but I understand that it is only a band aid. But it does help my ski start up when I need it.
Your ski is a 2007. It is 15 years old. It will require replacement of failing parts. That is a given. But I know you said this:
In kindness, I will tell you the unvarnished truth. Your ski is your pony.
To afford to ride, you will have to become your jet ski's mechanic.
Slowly by reading here and by reading your oem Service Manual, you will learn. These engines are bewildering at first, but in reality they are not that complicated. Everyone here will help you.
From reading your posts in this thread, my guess is that you are a brainyack in your career and in other areas of your life.
So, it is really your commitment to be your jet ski's mechanic which you must make. Not a lack of observation skills or ability to understand. It is up to you. You are right to come here and ask all of your questions. I am the king of stupid questions on this forum and I am better skier and mechanic for it.
Have faith, the people who answer questions here love the sport and love the people in our sport including you because they love the people who want to enter our sport.
Welcome back to skiing and the journey which will come with it.

Fair enough. Not one to shy away from a challenge. Any hints on where to start looking?
I can start it, just need to hit the starter a little longer than I would like and make sure I give it throttle almost immediately when it finally catches.

Dave: I can add to this post tonight, but here are few suggestions to get you started. Others will have more suggestions,
Bookmark this following link for its diagrams:
www.partzilla.com
We try to purchase parts from @JetManiac and @john zigler but sometimes have to resort to partzilla.com
Takes some more photos of the engine compartment in your ski and in addition posting them up here, just look at them until you can identify each item.
Don't work on it, just look at it.
The engine on your ski has a number of systems. Try to identify which goes with which:
Air Intake;
Fuel;
Exhaust;
Spark creation, timing and distribution;
Battery and electric charging
I looked for you for an actual oem Yamaha SERVICE Manual on ebay, and couldn't find one for your year. But look and save your search. Make sure it covers your model year.
Try to resist the urge to work on the engine of your ski without knowing what it is you want to do and have thoroughly determine the best approach to do it.
There will be times when it is broken and you have to take thing apart to test them, but resist the urge to take things apart now without a reason.
