So since I have no shore power, could the bilge switch itself be eating
up a whole zinc within six months? There seems to be an unexplained
drain of the batteries also.



Assuming the negative terminal of the batteries is connected to the block
of the engine, most are, AND if there is ANY leakage path between the
positive terminal of the batteries to the sea, yes, it'll gobble up the
zincs in no time....sometimes eating the prop, rudder, other underwater
metals connected to DC ground inside the boat.

When you say "bilge switch" are you referring to the bilge pump float
switch?
