[Alberg30] Zinc Anode location

[sousa, stephen (ENG)]

Calvin,

The Yanmar 2GM series did not have a zinc in the cooling system on previous
models unless they added this to the design. I would call you distributor
and ask them if Yanmar installed a zinc in the system. I looked all over my
motor and couldn't find the zinc, I have installed a shaft zinc onto the
Alberg.

Hmm...interesting...please continue to educate me: the engine comes with a 
zinc which the manual advises should be replaced periodically--what's this 
protecting, then? I'd somehow come to associate zincs with the 'siphoning' 
away of minute amounts of electric current and thought, since the shaft was 
a conductor, it might not matter where on the shaft the zinc was located.
