See full version: This is why your Waverunner is smoking
Another potential culprit for your Waverunner smoking is actually not smoke at all, but instead steam. This can be determined by how long the smoke/steam lingers after being emitted from your Waverunner. While smoke will linger for a bit, steam tends to dissipate rather quickly. here
This issue is also not uncommon in new Waverunner’s. New owners frequently mention encountering this problem shortly after purchasing their Waverunner from the dealer. While dealers are supposed to be trained experts on how to take care of these machines, some are better prepared than others.
If your Waverunner is smoking, it could be for several reasons. The best-case scenario is a batch of bad gas. That’s the most straightforward remedy, so if performance is not affected, then enjoy yourself. Maybe it’s time to find a new gas station. [links]
While this is a fairly common problem, you should be sure to address it as soon as possible. An underperforming air filter can cause other issues for your Waverunner and will hinder the machine’s overall performance.

Same here. I have also found this on my STX750. It is a two stroke issue. If you have any or used any two stroke yard tools (weed wacker, leaf blower, chain saw), you will find they have a primer bulb. I solved this on my STX by spraying starting fluid in the flame arrestor box. Easy on the STX but difficult on the XLT. more
Other than that, crank it for a while. If you do this, don't crank for more than a few seconds at a time. You can also purchase a primer kit for it also. You will find it at http://islandracing.net/watercraft.html [links]
I just purchased two 2002 Yamaha 1200 xlt runners and I am having problems getting them to start. I paid the local yamaha dealer $100 per ski to go over them and overthing was ok so I think I must be missing something. The previous owner did not have an owners manual and they are backorderd at yamaha so I though I'd try to gain some insight through this forum.
I have an '01 XLT1200. I don't think there is anything different between them.
One thing to look for is on the choke. When you pull it all the way up, there is one more trick. You will see a black, knurled ring that is around the bottom of the silver shaft of the choke pull.
Pull the choke up and turn the ring clockwise and it will lock the choke in place. If you don't, if falls to half choke position. here

What are key things to consider when it’s time to store my WaveRunner®?
Pre-Operation Checks and Maintenance: more
Dry corrosion occurs in areas not in direct contact with water—exhaust systems, for example. The outside of most exhaust system components is cooled by raw water to prevent overheating. When today’s ethanol-enhanced fuel is burned, it creates by-products known as sulfate salts. These salts are highly corrosive, especially when exposed to very hot temperatures. If the WaveRunner’s cooling water passages are not kept clean by regular flushing (the exhaust area in this example), hot spots can form on the interior of the exhaust components, concentrating the sulfate salts’ corrosive effects. The result is corrosion from the inside out. That’s why flushing your engine with fresh, clean water for 3 minutes after each trip is a vital part of preventing even dry corrosion. It helps the cooling system run at maximum efficiency by keeping the cooling water passages clean and clear, which helps minimize the heat inside the engine, making it less susceptible to dry corrosion. more
Preparing for extended storage efficiently and effectively means you’ll have a worry- and hassle-free experience when you return to using your Yamaha WaveRunner.
