Re: Mag or Alum Anode
here's the info from Defender anodes web site
http://www.defender.com/html/zincs_info.html
Zinc Alloy Anodes = Salt water only
Not recommended for use in fresh water
Alloy is manufactured to meet or exceed US Military Specification (MIL-A-18001K)
Aluminum Alloy Anodes = Salt or Brackish water
Not recommended for use in fresh water
Proven to last longer than zinc due to increased capacity
Alloy is manufactured to meet or exceed US Military Specification (MIL-A-24779(SH))
Magnesium Alloy Anodes = Fresh water only
Not recommended for use in salt or brackish water
The only alloy proven to protect your boat in fresh water

You know i have no idea whats on mine. I haven't had any sort of a corrosion issue though. I am sure its what ever it was from the factory.

Aluminum in these waters. Upper bay can be salty in drought years, but overall fresh enough for aluminum 'nodes.

Re: Mag or Alum Anode
Kicking an old thread because I have a question.
I moved from saltwater to brackish water about 4 years ago. I always had zinc anodes on the boat as it was kept in a wet slip the whole time - both when in saltwater (old home) and in brackish water (new home). Wasn't smart enough to figure out that I needed different anodees, so I've got some damage to my port pontoon that is going to require some repair.
My question is this: I have an aluminum pontoon boat, and I have to use aluminum anodes in brackish water. How does that work exactly? Aren't my aluminum pontoons GREAT BIG ALUMINUM ANODES?

There are several different alloys of aluminum. On top of that, aluminum alloys can be hardened to different levels through an annodizing process; a common practice when using aluminum alloys (most often T7075-T7076) for firearm frames.
I'm pretty sure that "aluminum" anodes would be of an alloy that would break down/corrode before the 'toons would.
