    that looks like your sacrificial anode......that is its normal appearance.....you do not have to do anything.....somehow, that thing is supposed to keep the rest of your motor from corrosion.....like the weakest link in a chain I guess.....something to do with the electrical current in your motor....they do this on underground steel pipelines to save the pipes.....ie, instead of the pipe corroding, the anode does.....

    now all you experts on this help me out to explain it.....

    PS is right. Most motors have them right above the prop. So they aren't noticed as much. If it is starting to chip or flake you should replace it, but it looks just fine now.

    Bruce is right, like the weakest link in a chain. It's sacrificial because it will corrode before the other other metal components due to its more active voltage potential.

    If you fish in salty water, you will have to replace these more frequently. I replace mine every couple years anyway. They are cheap and easy to replace. They are supposed to be a corrosion magnet. But always rinse your boat , motor and flush your motor if you put it in saltwater. But be warned this all only slows down corrosion. There is no way to completely stop it.
