You could even go Holley Dominator EFI but like the Terminator why spend the money on the additional features these systems have that would never be used. Who would need the 42 IO ports the Dominator provides? I guess you could flush the head..... All of the sensors and input devices on the...

Single Phase and Split Phase AC Power in North America It seems there is some confusion on how alternating current works in America - This graphic may help some - The green line is a 120 volt "hot" wire and the red line is the neutral. The voltage shown is actual peak voltage in a 120 volt...

AS EFI systems age they become problematic. The MPI's don't tolerate wear in throttle shafts well and what that play does to that fragile calibration. Their ECM's are bulletproof though. Half the battle in Mercruiser EFI is finding a mechanic that knows what they are doing not only to...

Many water heaters have the anode as a part of the water discharge fitting. Mine was on the Attwood in the 400DA.

Just renewed mine last month - nice place on the water on the coast - $3870. Includes wind mitigation at a 5% deductible. Does not include Flood which is FMEA - that was $800. Flood insurance isn't mandatory unless you should live in a designated flood plain and have a mortgage. What I find...

I think you'll find that a common issue in any desirable location. Speculative building starts are a year behind the market - who would have predicted mortgage rates up two points or more. Renters are staying where they are and owners wanting to relocate but need to finance (the bulk...

Besides a trailer to correctly support the gross weight it is necessary the bulk of the load supported from the boat's stringers and/or keel (location of the bunks) and the bunks to extend fully to the transom and yet maintain the correct tongue weight. Loadmaster are excellent trailers but...

In our area on the East central coast there is a housing shortage so they are throwing up crap everywhere. The county is revenue hungry but are failing to update the infrastructure to support. Where I live the voters passed unanimously a bill to limit one home per acre about fifteen years ago...

I believe you'll find your low voltage AC lighting is powered through one of the GFCI receptacles. So, look for a tripped GFCI outlet.

Ooooouuuuchhhhh

There must be a disconnect on the boat between the shore power and first device which will be an isolation transformer. That disconnect is typically a circuit breaker. Item 1 is a negative.

So, regarding the neutral conductor and the current it needs to support. Current reverses 60 times a second (US) and the neutral carries that same current. If you disconnect the neutral will anything 120 volt operate - of course not. In a 240 volt situation the two split phase hot legs are out...

Again, for @quality time - An isolation transformer does not have a copper path through it; that's actually the basis and reason to have one. Consequently, a ground fault protection device like an ELCI installed on the shore power will not do anything nor protect anything on the other side (the...

Isn't this apples and oranges? In your situation from our previous discussions your shore power will run into a Victron Quattro inverter/charger right? Consequently, the Quattro will switch/transfer the shore power directly to the boat's electrical system. So an ELCI circuit breaker would be...

Hey Dave - I wanted to follow up and clarify - These requirements ABYC, NFPA, etc are not retroactive unless specifically stated. So, if the ELCI requirement was adopted in 2015 for example then vessels built after that adoption would need to be compliant but nothing retroactive. There is an...

Looks to be voids under the gelcoat. They should be addressed as soon as practical. Fiberglass is not waterproof - water will wick on the fibers and eventually break down the resin. The longer the wait the more fiberglass will need to be ground out.

My advice regarding this - An isolation transformer should not be a band-aid to a problem elsewhere. If the boat is tripping a dock ground fault device there there is a bonified ground fault issue on the boat. Air Conditioning units, refrigeration, and water heaters are usual suspects...

The short answer is Yes. You have no control over the dock circuit protection even though that installation is prescribed by NFPA. The boat must protect it's self.

Like a GFCI the ELCI provides current monitoring to ensure feed and return current is equal or within a limit and will disconnect the power if over the limit meaning current is leaking somewhere else. The difference is the ELCI provides current limiting features (traditional circuit breaker)...

Additionally- with the addition of an isolation transformer the boat becomes it's own power source consequently, there is no need for the galvanic isolators. Also, your boat will become rather immune to power surges and sags. The isolation transformer becomes a great buffer to shore power...
