Any DIY portable anodes to prevent galvanic corrosion?

Hook it to your prop shaft

Entirely possible, I admit. I did some testing around and didn't see odd voltage/current readings that would indicate a short/bad ground, but I also learned my equipment isn't up to snuff.

Just placed an order for this jazzy addition that will hopefully help me pinpoint the issue (and blame).

I hang a "Guppy" anode often, but it's purpose is a as a witness, if it ever starts getting eaten up, then I know something is going on and I need to investigate, it is not to replace a prop of shaft anode, I have both, if anything I may be a little over zinced.

Not possible to "over zinc" because the voltage present is a function of the relative nobility of the materials present and maybe the details of the electrolyte solution they are in.

Except under limiting conditions (*under* zinc'd), the quantity of zinc will not impact the voltage present. So the current will not be affected. So the corrosion will not be affected.

At least that's how I understand it.

Fiberglass or metal boats, maybe not. Wood boats? Absolutely they can be over-zinc'd.

Ohhhhh right I've heard of that. Good point.

Its a thing.... And all your 'outside the hull' metal should be electrically connected.... you don't need to specifically connect this kind of thing straight to the drive. Neat idea if you are having trouble in a marina.

Then again if you are having that much trouble in a marina you should be asking the marina to investigate.... stray current is not good and potentially not just for the metal bits...
