If you remove the black cover under the front rack you will see your front air box, this has a wide mouth on the lower front side to induct fresh air into the box and then into two hoses one running to the main air filter box under your storage box and the other to the belt drive unit. If you hit a water hole that is as deep as the grill fast with the front end it can suck up water into that box then it can get into the main airbox causing water to enter your carbs, this will cause it to stop running, also your crankcase vent is in there too, allowing water to enter your oil, This can cause the motor to be ruined if not flushed many times by changing the oil and filter. Thats why getting in deep water is a big problem unless you have done as many and rerouted those intake hoses up higher, this is snorkling. Its not a problem as long as you know your limits, a stock V2 is good to the top of the tires as long as you dont run fast into a water or mud hole forcing it into that front box.
