Best way to flush out a motor with water in the oil

[bbluesilver]

cheers, the grease/oil in the housing was pretty white, so yes you might be onto something there.
the oil that I drained was a lightish brown colour, so guessing it has a little water in there somewhere.
no leaks or anything around the motor, all looks pretty clean.
Was thinking of just doing the flush, putting cheap oil in, run it a little. drain it, then good oil and filter
