Remove old AC thru-hull?

I would like to install a new 15A plug-in (for my new 12A Promarine battery charger) in place of the existing ancient and disconnected AC shore power receptacle. Is there some way to remove this old thru-hull fixture, or would I be better off simply drilling a new thru-hull?

Greetings,
Mr. Sunset. Thru-hull or thru-house? Below the gunwale?

I hope you are not thinking of running shore power directly to a battery charger. I'd want photos and a schematic before answering your questions because I'm not sure I understand.

The thru-hull I am referring to is located on the vertical surface of the wheelhouse.

The charger is the 43012, and comes with regular 3-prong 120V cord and plug.

ProSport Series | ProMariner

The inlet is like this, but without the hard-wire set-up. IOW, you use the 3-prong plug that is already attached to the power cord of the charger.

If one were't to plug it into 15A shore power, I don't know what the heck they would do with it. My shore power is a regular 15A plug in.

There are replacement 15 amp boatside receptacles, you need to follow some safety install ideas if that's important to you...probably come with the new inlet.

That's what I would do or even better...upgrade to a 30 amp inlet/panel so I could expand if needed....assuming cash is available for the upgrade.

Each POS line on the outlet cords is protected by an inline fuse. The installation instructions - re power source - call for plugging into a UL approved HD power cord, which is to be plugged to a 120V GFCI outlet. Seems fairly straightforward, right?

As an aside, I have no desire to provide for any more advanced shore power for this particular boat. Less is more.

So - am I missing something?
If not - any thoughts on whether that old power receiver can be removed and replaced?

sure just use that marinco bulkhead adapter and hardwire the charger to the backside and run an extension cord to it....not the best way but certainly the way many do it.

The really critical stuff for your protection will be on the dock side of things...that's where you need to ensure all safety issues...if you care to do so.

Unhappily I don't think it is within my authority to deal with the marina's crappy 15V outlet by installing a proper locking system.

How about the removal issue? Anyone?

I don't know what a "POS" is or a "power receiver" tut it sounds to me like you are going to hard wire a battery charger without circuit protection onboard. I also suspect that you have no intention of bonding the AC ground and DC negative. If I am correct, you will have an unsafe vessel.

It sounds to me as if you may not have read all of my remarks.

POS = POSitive. "Power Receiver" is just another randomly chosen term for the ancient existing Shore Power Receptacle, being the principal subject of the thread. Sorry for not having the precise term for this item.

In planning to complete this installation I have tried to follow the instructions set out here:
Installing A Marine Battery Charger Photo Gallery by Compass Marine at pbase.com
although mine is a much simpler setup. I intend to include provision for grounding the charger case itself.

I will give further thought (and research) as to whether the inline fuses are sufficient.

Meantime - no ideas as to removal of the old shore power outlet???

I have read all your remarks and I'm sorry but making up your own "randomly" chosen terminology and using terms like throughulls (a seawater connection through the hull) improperly makes it very difficult to understand.

Love to help but I still don't under stand where these inline fuses are supposed to be... in the power supply cord from the charger (not likely).

For the inline fuses were talking about 12 V right? If so they have there own inline and there's no need for adding extra fuses. Also how many and which type of batteries are you charging? As for taking out the old receptacle, if the holes to big goto Home Depot and buy some plexiglass cut it to fit over existing receptacle hole and then cut smaller hole for the new receptacle in it. Also if there's not enough wire in between just go buy some marine grade triplex cable accordingly sized 12 AWG would be best but could get away using 14 AWG, just make sure you use marine heat shrink connectors between them.

Boatpoker ----> You are correct, a thru-hull does connote below waterline fitting, although I doubt you would expect to find a "AC shore power receptacle" there.

"Each POS line on the outlet cords is protected by an inline fuse" and I don't mean "piece of ___" (or do I?). By outlet cord I mean the lines leading from the charger and connecting to the batteries.

Please understand that while I am eager to receive all comments relating to electrical issues, my lack of precision in language here is because I am actually asking about removal of the deck fitting.

usually 4 screws or bolts and it's toast...what's the issue? you can buy replacement ones that will usually go right over the hole and use the same fastener holes....is that what you are looking for?

You still need circuit protection (a breaker) between the shore power inlet and the charger.
