in most cases the GIs have 4 diodes in them for 1.2V drop/isolation. (2
in series in each direction) Selecting components for a given amp rating
is not hard. B

Although there are other practical reasons to have two devices I don't think
the power source of the receptacles app
Also, the ProMariner FS Series is a “fail-safe” type isolator; no remote panel
needed. Under $300 for a 30-amp unit.

Steve — the “fail-safe” versions of galvanic isolators are also ABYC-approved,
and don’t require the remote panel. There’s a company up in our neck of the
woods that started out making electrical equipment for dairy farms; they
realized that their ground isolation products would also work well
Since we're on topic. It seems that there is a bit of differing opinions
on bonding the under water metals.
What are the shaft and prop zincs protecting? If a shaft coupling isolator
were installed and no bonding wire attached then the chance of stray
galvanic currents is eliminated. Right?
I understand the need for a failsafe mode. However if there is no indicator
light how would you ever know it failed unless you put a meter on it and
tested it periodically?

Joel —it would pretty much take a direct hit by lightning to cause one of these
units to fail; if that happens, you’ve got other issues to deal with… :^)

To answer your question about “What are the shaft zincs protecting?” Assuming
you are in saltwater such as the Chesapeake,
Just a few things, including: the prop, the shaft, the rudder post, the keel
bolts
this yourself, unless you can design the proper size diodes
and capacitors and heat sink the box
Just my$.02

Does anyone use one of these:
http://www.defender.com/product3.jsp?path=-1|328|2290032=605562
Does it slow/stop electrolysis? Most of the boats on my dock are plugged
in, and I go through a zinc or two a year.
Will an isolater do anything besides lighten my wallet?

I put one in when I refurbished my A/C electrical side.
It isolates you from your neighbors which might slow down the zinc
consumption ... unless of course it is issues on your own boat causing you
problems.
Many surveyors would recommend one if you are in a marina with shore power.
