Transom ground (zinc? anode).. should it be wired to something?

[kippstakes]

there is a ground near my drain hole in my transom. what is it for? i remember hearing that it has something to do with the gas tank and spark prevention. my tank is all plastic, so maybe grounding's unnecessary. that said, do i need to ground it to anything else?
thanks

The zinc anode is used to prevent corrosion on your engine; it is not grounded to anything, do not paint it.

sure. my engine has a zinc trim tab under the cav plate, but i'm wondering about the plate mounted in my transom with bolt on the back of it for a wire lead mount. it goes thru into the bilge where a wire is attached-- i'm wondering what this wire is for. seems like some sort of sea ground, so to speak.
any ideas?

Does it look like this?

It's for attatching a heavy ga copper 'bond' wire to a metal fuel tank. Believe it's called a 'bonding lug'. Usually bronze, not zinc. It isn't an anode per se.

Regardless. Your plastic tank renders it obsolete.

that's the one. kind of figured that was the case.
thanks for the info!
