No, his gimmick is based on the fact that he liked scuba diving, the old racist stereotype about blacks was that they can't swim. He was also created as a "cool" character, so he was not stereotype.
Whitewash however...

I admit I don't know how to swim, but never knew until now there was some sort of stereotype about it (not going to ponder where such a notion came from, and probably don't even want to know...).
