If I'm not mistaken, the lack of an 'engine zinc' on the 3GM30F engine  
lock is because it uses an interior cooling system which is filled  
ith 'antifreeze/coolant' (like Prestone).  The coolant is further  
ooled by pumping raw seawater over/through a 'heat exchanger'.  Thus,  
he interior cooling passages of the engine are kept separate from  
orrosive seawater.  Some (older) engines have no such cooling system  
nd simply pump raw seawater through the engine cooling passages.   
hose 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?
