Water Locked…?

My buddy and I went to M&M today to try out the new Reapers! Little icy so hard to really gauge, but what I got to experience I really liked a lot.
That was until my buddy ended up upside down in a 3′ waterhole that ended the days riding as his quad shut down and appears to have sucked water. It will not start. Any easy way to drain this or just have Polaris dealer take care of it?
