This 4th O' July long weekend on boat I plan to put on new anodes for each shaft, both rudders, big "license plate" bonding system between trim tabs and on trim tabs them selves. Recently I put new pencil zinks into engine cooling systems.
Our boat is exclusively in fresh water.
Here's my question:
What is wrong with [i.e. is it detrimental to anode or diode metals] to mix different kinds of anode metals attached to diode metals for hopefully maximum corrosion determent?
In other words... What is outcome if I put a Zinc, and Magnesium / or Zinc and Aluminum / or, all three anodes on the shafts - with Magnesium in all other anode locations???
It's not that I'm experiencing corrosion trouble at all - just wondering about anode mix on the shafts... seeing as I'll be under boat playing around with anode replacements anyway!
Input always appreciated!!
