[C320-list] Zincs

[Morey Waltuck]

I use a Godfrey zinc.  They are twice the cost, which is insignificant.  It 
is an assembly of zinc over a brass insert.  When you attach it you are 
actually tightening the brass insert onto the shaft but all that is exposed 
is zinc.  So, no matter how much of the zinc corrodes away (usually about 
1/4 on our boat), the unit is still securely attached to the shaft.
