A question for the corrosion experts here on TF
My Mainsdhip has a Yanmar 6LYA engine and ZF transmission...
While checking / changing anodes recently I found the tranny Heat Xchanger anode was broken and stub stuck in the HX...removed the HX to take home & work on it in the shop. Drilled the stub out and cleaned up threads and cleaned & flushed the raw water side.
While looking at the mounting I noticed the bracket is rubber lined and HX held on w/ hose clamps.
My question - does the HX anode need to be connected electrically to the engine / boat ground to protect the HX or only be connecetd to the HX body?
I know external hull / running gear anodes need to be grounded to protect all under water gear and wondering if the same is true for engine / tranny HX's or does each anode protect each HX independently w/o a need to tie grounds together.
Any advice and expertise apprecited..
