Question Replacing zinc on Yanmar 20M20F

I am new to sailing and own a 2001 Hunter 320. I was reviewing the Owners Manual to the Yanmar 2GM20F and it states you should replace the engine zinc every 300 hours. The manual indicates the cooling system is a "Fresh water cooling with heat exchanger".

My question is, where is the zinc located?

Thanks for any help!
