Super Jet Need Help - SJ with water in engine??

ski: SJ 701 ADA 33cc 200psi both cylinders, enhancer bpipe.

Ski runs perfect, but when i turn it off sometimes it won't start again. When unscrewing the sparkplugs turns out its "full" of water.

Has happend one time when the skis was lying on the beach, and a few times out on the water when turning of to rest.

Has 200psi on both cylinders so cant be o-ring in the head. I doubt water can come from exhaust all the way trough waterbox and through camber and into exhaustmanifold?

Have this wamilton carbon airbox intake witch looks pretty damn unsafe but the skiis runs 95% of the time.


Damn annoying when the suddenly stops? Cant really trust it so i need to get this problem solved. Doesn't think there is an easy logical problem so was hoping someone of you had some experience with this complex problem and could give me some ideas or hints of what could be the problem?

Regards Magnus Sweden.
 
I had an exh mani leak that would do that..
Maybe try blowing/drying out the cooling lines when you shut it down.
Help narrow down the source a bit.
Generally with HG leaks your pisser water will pulse from the combustion pressure
getting into the cooling water/hoses..
