It stayed under water about 45 min. before it got winched out, drained, drained and drained everything again and it was cranked back up that same day, oil still needs to be changed a few more times......So it will survive!
For the record.....My Argo did not sink....it was the Maxx.
He was crawling up the rocks and hung it up ....put it in reverse, tires grabbed somehow in the rocks and pulled the back in under water...10 -15 seconds is all it took!!
