Actually, dive could be strong in OE. There were two verbs, dūfan (strong intransitive) and dȳfan (weak transitive), so you could say for instance ic deaf under yþe ‘I dove under the waves’.

But that is just to draw attention from the fact that I don't really know the answer to the question..

I'm thinking of sneak –> snuck, but I don't think that even existed in OE.
