John,
Generally, yes to the first question, but you still have to make certain
that water flows around the part and it should be 316, 316L or 316Ti.

Yes it can to the second question, but to a smaller degree. However, it will
raise hell with other metals attached to the same electrical plane and the
extent also depends on the bronze alloy.

Interesting...
Is stainless okay below the water line in fresh water?

Bronze is an alloy; does it act like millions of batteries in salt water
also?
