x2!!
I hydrolocked the engine in my explorer 3 times... never had an electrical issue. Each time i was able to get the engine running again. After the 3rd time i built a snorkel lol.
BUT... the damage took its toll. I must've weakend one of the connecting rods because pulling out of work one day it broke and punched 3 holes through the engine!!
That was a fun wheeling rig!!
Moral of the story... if you're using "but you'll just get the electrical stuff wet so i dont see the point" as your excuse for not getting a snorkel, you're sorely mistaken. The electronics aren't a big deal. However, you do want to make sure you extend your vent lines and check you diffs/trans/tcase fluids afterwards and change them on the "severe" cycle since there will be some water ingestion.
