I am not enough of an expert on electrolysis to know, but it probably
will work.  I'm just thinking about how the current might flow in the
damaging electroylsis, and having the zinc electrically attached to the
engine seems like it would make sure that the zinc goes first and not
the case.  Pure conjecture on my part, and probably bogus.   I think the
best solution is to stop the electrolysis by good grounding and keeping
the highly conductive acids from forming in the first place.

We need a marine engineer who specializes in this on the list!
