It’s the large plug partially around under the front on my heat exchanger and the plug has an anode on it. I installed a bsttery maintainer and leave it plugged in all,the time - slow smart charging that keeps the batteries in good shape.

Definitely jack up the toung then drop the outdrive like cfelton says and if mine weren’t kept in my shop, I’d do what Destroyer says and add some heat and circulation under the cover. I cover mine to keep the sawdust and chips from the lathe from making a complete mess out of it..
