It's called a sacrificial zinc anode. It prevents electrolysis. If you put two dissimilar metals in an electrolyte solution (salt water or other conductive liquid), it will create a tiny electrical current which will cause one of the metals to break down (you may also recognize this as what we commonly call a "battery"). You put the zinc inodes on a boat motor and other metal partsbecause the zinc will break down first, thus preserving the motor or other parts.I think it is a zinc piece which prevents rust in boat engines, including ones with salt water cooling system. not sure about right name.
No.........the conditions are not applicable. Electrolysis caused erosion is NOT rust........two entirely different conditions. Zinc has nothing to do with rust whatsoever.Zink will probably work when it is raining or high humidity.
I was told zink will work only if I use sea water...This topic will zinc..
If you´re so cheap that you use only water as coolant, then you would need a sacrificial anode inside the cooling system.
And that in car systems because they use iron engine blocks, bikes have all aluminium systems.
You dont need antifreeze in Florida but you need the anticorrosion factor
