hat's a Galvonic isolator to protect against stray shore power DC leakage.  Its 
 great feature Catalina adds.   It doesn't replace, in any way, the need for 
rop shaft Zincs however. It helps prevent your AC system from contributing to 
he corrosion problem. 
Its worth a quick google read to know what to expect (and what not) from it.

f I'm not mistaken, the lack of an 'engine zinc' on the 3GM30F engine  
ock is because it uses an interior cooling system which is filled  
th 'antifreeze/coolant' (like Prestone).  The coolant is further  
oled by pumping raw seawater over/through a 'heat exchanger'.  Thus,  
e interior cooling passages of the engine are kept separate from  
rrosive seawater.  Some (older) engines have no such cooling system  
d simply pump raw seawater through the engine cooling passages.   
ose engines need 'engine zincs'.

 My engine manual talks about a zinc in the engine; evidently it is  
in a
plug which is supposed to be identified as ANTI CORROSION ZINC. I've  
looked
all over the engine and cannot find it. I have the Yanmar 3GM30F.
 Help please?
