I have traversed an ocean stream of about 100 yards even with the top of the fender openings(actually water was crowning over the fenders) with no trouble. I had a D full of dinner guests witth me and had to get back to our camp site. If you're familiar with the Pismo, CA creek at high tide you know the one I'm talking about. Of course when I got home I serviced the entire driveline to eliminate any water contamination from damaging the same. Just go slow and easy.
