Thanks for your tips and advices. Writing you from France. Bought my first jet-ski after watching your videos. A 2008 Ultra Lx. I enjoy it so much !! Just one problem. Sometimes, when using it for fishing in the ocean, if I stop the engine too long it won’t start back, water is coming up from the exhaust to the engine ... when this happen I have to take of the sparkplungs, make the engine run to clear the water and put dry sparkplugs I carry with me ... Any advice for this problem ? Merry Christmas to all of you 🥳❄️☃️
Water in the cylinder when you shut it off make makes no sense. You are sure you are getting water in the cylinders? Your ski has the same temp sensor as older 12f and 15fs. After the engine gets hot and you let it sit a while it can sometimes turn over but not start due to heat throwing the overt temp sensor into play. Pouring water over that sensor will cool it off and let you start right away. But water in your cylinders is a whole other animal that needs immediate attention.
@@edwardbowles8613 Thanks for your message. Being a beginner in jetski I'm not sure about what I wrote. This explanation was given to me by an other owner. Waves hitting the back of the ski could push humidity into the cylinders. Never heard about this temp sensor problem ... maybe the time its takes me to change the sparkplugs just let it cool down. It only happened twice but one time I was quite close to the shore with 7’ plus waves ... this was a bit stressful so I hesitate cutting my engine too long when fishing now
Was the ski a saltwater ski? How many hours when you got it? It could be that there is a crack in the exhaust manifold or head and water is leaking into the engine that way..or somehow getting into the airbox...not likely as far as I know that water would flood the engine through the exhaust unless maybe waves were slamming into the back and forcing water in...do you have the stock exhaust tip? Hard to diagnose the issue without the ski...as you understand
@@JDsWaterWorld thanks for taking time answering. My jet is 210 hours and was mainly used in the Atlantic ocean in the area of Hossegor and that’s where I still use it. It has 210 hours but had a new manifold and first water box - this model has two water boxes. The jet pump has also been rebuilt. Except this problem it works fine. After 4 or 5 hours sailing I almost have no water into the hull. I thought this was a conception issue common to these kawasaki riding in choppy ocean ... but reading your answer I suppose it isn’t ... I investigate on your suggestions. By the way .... love your videos😊
Of course thanks for watching! So new manifold...are you sure it was sealed correctly and is not leaking? Sometimes if the mating surfaces are warped it could be leaking water into the engine...the gasket should be an OEM type gasket- sometimes people use crappy aftermarket gaskets that don't crush properly..if it was me- and I had just replaced a manifold and now was getting water in my cylinders- I'd suspect maybe the manifold was improperly installed- check the gasket and make sure all hardware properly torqued!
It's interesting because the STX and SXR have a MAF sensor, but the Ultra LX does not and has the older aluminum manifold...they all have the extra flame arrestor, although only the newer models
Merry Christmas to you and your family, still following your amazing channel, can't wait for spring🤙🤙🤙🤙
Same to you man!!
Very cool. Thanks for posting this and Merry Christmas today!
Merry Christmas JD. Thank you again for letting us see what's in store for us, it's good to know what to expect. 😂👍

Please let us know, my 2023 STX must have the same setup
Yes, same setup!
Can that potentially make the air/fuel ratio leaner now?
Perhaps, but there is no boost involved or anything so it would likely be very marginal.
It's interesting because the STX and SXR have a MAF sensor, but the Ultra LX does not and has the older aluminum manifold...they all have the extra flame arrestor, although only the newer models
Is this in the 2023 ultra 310 as well?
Not on the 310!
Does this work for the sxr?
Yeah it's exactly the same intake as the Ultra LX
