mine looked just like that this weekend but it was a mud/water whole and it died but i do plan on a full snorkle and new exhaust and ill def dielectricYou need to get an exhaust snorkel at a minimum so the exhaust stays above the water. It would seem that too much back pressure is killing your engine. You could also make sure you idle is set high enough or just try keeping the rpm up when you go through that deep of water. Here is a pic of me deep in the water but the motor never died. However, if you are planning on running deep in the water often then you should full snorkel and dielectric grease all electrical connections including your plug boots.
The thicker the liquid the more pressure it requires to keep the engine running so mud only makes the problem worse. The intake side is more dangerous when it comes to water but you can also cause yourself problems if the water backs up into your engine from the exhaust side. Typically if it dies you want to tilt your atv on its ass so the water drains out the exhaust.mine looked just like that this weekend but it was a mud/water whole and it died but i do plan on a full snorkle and new exhaust and ill def dielectricYou need to get an exhaust snorkel at a minimum so the exhaust stays above the water.

Some say it may be a safe sincer so it won't get hurt I think the exhaust is the problem I'm hoping anywaysMine does the same thing but when packed with snow. People say its the key but I think its shorting out.
