snorkel kit?
 

2013 Polaris 850 xp
looking for an aftermarket snorkel breather for my ride.
I can't go in water any deeper than 2ft or I'm sunk.
Any suggestions?

Stay out of deep water.

2Ft is deep? LOL

I think your XP has a leak somewhere else in it breathing tubes.
Loose tube clamp connection somewhere or some electrical thing does not like getting wet.

Stock you should go through water up to your seat. The stock air intakes should be atleast at gas tank height. My 500 Sportsman is stock and I kneel on the seat on some water crossing with the pipe under water bubbling.

2' what's that, like just over the floor boards and not even to the side panels.?

You should be able to go this deep stock.

The problem with going through water this deep is that you can't see the bottom. You hit a hole and in a second the water is up over your handlebars. I'm not 100% against water crossings but use some common sense. If you can drive around a pond, then drive around it. If you're not sure how deep the water is, walk out there and check. That being said, 2 ft doesn't sound that deep. Up to the fenders is usually safe. But sometimes the water gets progressively deeper or you hit a hole or rock or something that you can't see and then your quad is laying on its side sucking in water. Was that little water crossing worth having to get your engine completely rebuilt? Most likely it wasn't.
