I see all these videos of guys going deep in the water with the exahaust under the water. Man that looks like fun!! I know about the snorkeling and the rerouting of the vent lines and other stuff. But what I was wondering is, if the engine stalls while the exhaust is under the water, will the water enter the engine and cause problems. If so is all you have to do is change the oil and keep riding or does something else have to be done. I realize that with the engine running the exhaust will keep water from entering the exhaust, but what if the engine stalls.
