[Public-List] Prop zincs?

[John Birch]

Randy, either you or your neighbour or the marina itself seems to have a 
stray current issue.

Do you plug in all the time in your marina ?

If so, start with your boat - I'm no expert on this stuff, but x2 seems 
awfully zinc hungry.  What kind of charger are you using ? Please don't tell 
me it's a crappy hookup automotive one - they should never be used anywhere 
near water, they can charge the water surrounding a boat with a more than 
lethal charge.

And no, the fuses won't stop it. Not necessarily .... That's also why we do 
not allow diving or swimming in our marina.

If a diver is employed, they are commercial and we lockout the entire marina 
electrical system - and our's is properly done electrics too - water, 
electricity .... ugh, bad trade.

Best

John
