HELP!!!Submerged sportsman etx

I had the unfortunate event of putting my brand new sportsman etx up to the racks in water yesterday and let’s just say things didn’t go to well because I didn’t make it out the other side of the deep a$$ puddle. I shut it off as soon as I heard it start to die and I knew I wasn’t making it across. Then I dragged it out and stood it straight up for a solid 30 minutes to drain water out of the muffler. Then after waiting a while I started it back up finally and was being an idiot and decided to drive it for another 2 hours. Probably was a terrible idea and I’m regretting it now but it seemed to work fine for the rest of the day. I don’t know if it is to late to do anything now but if not what should I do?
