Electrolysis, otherwise known as galvanic corrosion

Begging leave to differ, Capt Frank, but they're two different things. What
you're describing is galvanic action caused when dissimilar metals immersed
in an electrolyte decide to act like a battery and generate electric current
all by themselves. Electrolysis happens when an external source of
electrical current, like your starting battery or shore power supply,
generates electrical current through the water.
