- Zincs are indead a 'consumable'. The reason you have a zinc on any metal
- parts coming in contact with salt water is because of electroliis (sp?).
- The zinc is a soft metal and corrodes away, thus saving metal parts (like
- your engine) form corroding. Nifty little trick. All the commercial
- fishing boats that I know of use zinks not only on the engine, but also
- on trolling wires (wire rope), skegs, any metal parts that spend any
- time in the salty brine.
