Ok I went into a shallow river around and got pinned against ice and while trying to get out of the river water got into the large intake ontop the engine enough to start making the engine sputter... I shut it off as soon as I new water was in the engine but I might have been to late it started to lose power before I turned the key. But at no point did the entire engine go under water or I. Completely sink the argo. I'm not a mechanic but I'm a quick learner and I m familiar with atv engines and general maintence on trucks i just don't want to ruin the engine
