Hi Michael:

Nope. The only zinc you need with the freshwater models is on the prop 
shaft.

Hey, I’m wondering if anyone can tell me if the Yanmar 3GM30F has zinc 
anodes in the engine block (or anywhere else) and where they are located.

I have a service manual shows zincs in the 1GM10, 2GM20(C), 3GM30(C) and 
3HM35(C) but no reference to the “F” model.  I recall coming across another 
source that said the 3GM30F does not have them.

Thanks for the help,

Michael
