Re: 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).

Re: Any DIY portable anodes to prevent galvanic corrosion?

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.
