Godzilla survives well in water. Kong didn't trounce Godzilla, finish him off, or anything like that. Technically, Kong may have "won" ... but he needed the unfair handicap of getting juiced with electricity to hold his own against Godzilla. Earlier in the film when the two met and Kong was "chicken" gives you the proper idea of who could whip who -- and that's The Big G beating the tar out of King Kong.

(Then again, Godzilla relied heavily on the advantage of his fire freath, so...) 
The electricity was like Popeye's spinach. Next time you watch the film and Kong gets struck by lightning, start humming the Popeye theme song to yourself...makes it much more acceptable
