Which type of anode?

[dcartie]

I have a great condition. 2004 bravo 3 with anodes that are reaching the end of their life. The extra ones I have are heavy so I'm assuming they are aluminum and the boat is only freshwater. Is the conversion to magnesium worth it? Or do I stay with aluminum since they've done well? Thanks!

If the OEM Zincs have been working well, Why rock the boat?
Go back to Merc and get OEM replacements.

Zinc? Aluminum? Magnesium?

Zinc is heavier then Aluminum. If you haven't done it already pull the props off, and look for corrosion. My personal experience shows the corrosion will start on the hub behind the prop. I'm in fresh and use Aluminum
