I certainly wouldn’t recommend trying this out even if you know that your snorkle system is well sealed. Sucking water into your engine will cause whats called as hydrolock. Water does not compress in the same manner as air. So when water gets into the cylinder of a running motor, somethings gonna give and usually its either piston rings, gaskets, seals or something worse.
All that being said, check out the video and prepare to be in awe!
