Your atv looks like a Polaris Sportsman. Is it? What motor does it have? I've got an 06 Sportsman 500 and love it, though I've never had it in water/mud as deep as in your pics. Have you had any trouble with crud getting in the belt or ingesting water into the air box? I'd love to try some stuff like that but am a little paranoid about damaging the thing.
