    Default Looks like its time to replace my anodes

    For what ever reason... I found it interesting what a season and a half in my motor did to these. I would show the other one but it is gone completely. I'd like to think my heads look better than this.

    Looks like a good idea to keep some in there.

    its a plug with a sacrificial metal attached(usually Zinc) that will keep brackish water from eating at aluminum parts of your engine. It just eats this instead.

    Is there any benefit to running these in fresh water? I noticed my intake was pitting around the water ports the last time I had it off. This was after half a season. Where do you install them? Intake, Block, Head, Does it matter?

    Isn't there an anode is all hot water heaters? Seems like it is a different material depending on water hardness in the area. That is not brackish water.

    Do you always run in salt or brackish? If one is missing, and one half gone, I would replace them more often. Zincs will usually protect until there is nothing left, then they will wear on the metal it's supposed to protect. Even with that little stalgtite you have, I'm sure it was doing it's job.

    Just about all water has some salt content and minerals that will take there toll especially on aluminum so yes the anodes are a good idea. If you have ever noticed, all outboards have them as well as lower units to protect them. They are usually ate up if their very old.
    you can screw them into just about any hole that goes into the cooling system.

    i thought galvanic reaction was caused by the rotation of parts and dissimilar metals in a wet enviroment

    Thanks for the link. Those are much cheaper than Summit. I'll be adding them to both boats this winter.

    Question

    Where would you install them > in the block drain locations?
    In an open cooling system once the engine is off, water normal drains out to the water pump inlet holes.

    For what its worth...I got a anode lesson a couple of years ago when I blew up my 427....it was 2 seasons old. My heads were getting eaten alive. Btw...no brackish water here......just fresh.
