Oh! I hate to ask where the zink should go? I haven't seen anything
mentioned about it anywhere! Is it a pencil like my crusaders?

Now you got me thinkin...

I may be mistaken. It may have just been a drain hole with no facility for
a zinc but I have a hard time with the fact that there'd be no zinc on the
seawater side of a heat exchanger.

Yes, if I'm right it's the pencil type. May be located elsewhere on your
model.
