How Effective is your boat's Electrolysis Protection?

If you are still using the old fashioned and inefficient cast magnesium Anodes, the answer would have to be........"not very"

Why wouldn't you install the World's most efficient anodes to protect your investment particularly if that efficiency is available for no extra cost?              Throughout the world there has been a massive swing over to "extruded" magnesium sacrificial anodes from the old standard "cast" ones because of their resultant immense increase in efficiency. This increased efficiency comes through the far greater "purity" of the extruded material than foundries are able to achieve with normal casting methodology....up to 70% greater!

This is just what you don't want to see on your pontoons or hull.
That's what electrolysis looks like!

And this is the reason why you could. Nearly 40% of this typical cast anode was consumed through internal corrosion of its own impurities....this was not available to protect the boat from electrolysis.

A modern extruded magnesium boat anode ready to protect your expensive asset.  EBA333M2

The same anode.....years later and still showing a completely even material consumption
