Zinc for my 84' hunter 31

[Tom Fritz]

When entering the cabin beneath the steps is what appears to be a 3" x 5" zinc under a large bolt and nut aft of 2 other large bolts and nuts that are the aft keel bolts.
-First question is where can I find replacement zinc and is there an issue removing nut to replace?
-Second is I'm powered with a 2GMF 13HP Yanmar, is there engine zinc that needs to be replaced?

What does you engine manual say about an engine zinc? What does you boat manual say about keel zinc?

 

[sail sfbay]

Is this your manual? If so, the section 8 refers to engine anti corrosion zincs.

There is no engine zincs on the freshwater Yanmars 2GMF and 2GM20F. The manuals refer to the sea water cooled versions and then in the addendum on the back where they describe the fresh water cooling system they fail to mention that no zincs are needed. Took me a while to confirm that.
