Cabo Express Electrolysis

On my Cabo 43 the ac pump is 240v and the fresh water pump located under the galley is 120v. The fresh water pump is plugged into a 120v receptacle under the galley. The 240v ac pump is hard wired. Hope this helps sorry been away.

Bill,
I have 2.5" shaft zincs on my shafts although I was told they were not necessary after installation. Will probably not replace when they have deteriorated.

That's a very good link. I wonder why they only make them in 20' lengths. Even the WM one has a 20' length but then you can purchase a 20' extension or multiple ones for it.

What part of the panel is it on. Each section of the panel should be labeled at the top of it as to it's voltage.

That's a very good question. I have never noticed it before but will spend some time trying to find out. I can't think of any electrical reason. Maybe it is just a convenient length for most users and it simplifies inventory?

Probably simplifies inventory. You can buy extension lengths of it.......also in 20' lengths.

This source pretty much shows that lead length is whatever it needs to be and their standard is 50 feet. Note that several of the cells don't even come with wire attached so you can use your own.

I have had one for a couple of years that I got from reliability-direct and use it with a cheap digital meter. The meter and electrode live in a little plastic box from Office Depot. Use it, flush it with clean water, let it dry and store it away until needed. It makes me laugh to see what some surveyors charge for doing a "corrosion potential survey."

Next thing might be a "primary cell electrical potential differential analysis" which is performed by sticking the leads of a volmeter across the battery terminals.

AC panel is on the left. All my 240v double pole breakers are at the bottom of the ac panel. That includes the 2 ac units, the ac pump, water heater and battery charger. Total of 5.

Mine is 2005.

Somebody on this thread mentioned "hot" boats in a Marina, I'm sure every Marina probably has their share of "hot" boats. Is there anyway you can install....I don't know, a galvanic isolator to insulate your boat from other "hot" boats?

Yes you can install one and it's generally relatively easy. Most boats come with them from the manufacturer, but it's recommended to change them every so many years.

Capt J, can you tell me what the system is composed of? How is it tied into the electrical system? Thanks,

It is a magic box that burns off any electricity or absorbs it on your shorepower a/c electric system, something along those lines. Galvanic Isolators use Isolation Diodes to isolate it. It is usually connected very close to where the shorepower comes into the boat and you basically create a break in the green wire, connect one side to one terminal and the other side to the other terminal of the galvanic isolator. They usually not too expensive for a 50amp one, $300-400. If you have an isolation transformer like Hatteras installs and others, you don't need a galvanic isolator as the transformer does it.

The West Marine advisor has a good article on marine grounding systems which covers all of that.

Have you checked the grounding on our motors?
