CAn someone please educate me on the fresh water inlet.
I noticed the water in my tank doesn’t last. Finally saw this running whenever I turn the water pump on. Given it’s my first boat with water inlet, I am Not sure if i am supposed to close this somehow or if it is broken. Just keeps spinning.

That is for direct hookup to marina water and bypasses your tank. That it's leaking says to me that a check valve may be allowing flow. Do you have the parts manual for your year/model boat. That should have a diagram of the water system. Someone else may have direct knowledge, but that's where I would startt.

As posted, That’s your dockside water hook up/pressure reducer. You hook your hose up there when you want to use city water rather than the water in your tank. It has a check valve in it that keeps water from leaking out when using the water pump to draw from the tank. You need a new one.
 
What you're spinning isn't a valve handle, it's just the female end of what you'd find on an ordinary garden hose. You could get by by merely inserting a garden hose cap, at least long enough to verify that that's where the leak is.

Whenever I turn on the water pump at the helm, water flows out of this thing non-stop. And it doesn’t stop until I turn off the water pump at the helm. It just keeps spinning as I turn it.
I am just trying to make sure it’s actually broken before replacing it and that it isn’t something simply left open during winterization.

If water is coming out of it, it is broken. Replacements are available at west marine or amazon. a few screws and the whole assemble comes out of the transom panel. then disconnect the back and connect to the new one.

You can skip the first 2 minutes of this guys video but he then covers the basics.
 
The PO left a quick disconnect fitting in there. I tried everything to get it out (heat, PB blaster etc). Nothing worked and I ended up cracking it in the process, so it leaked -- cycling whenever I turned on the water pump.

Easy to replace: just remove the 4 screws, and there is a blue hose threaded on to the back.

I got this one from Shurflo. The only problem was, it's a little bigger in the middle so you have to widen the hole in the boat a little bit.

Sometimes water pressure with the hose can stop that leak. I always fill the tank and never use the dockside city connection. When mine was leaking, someone mentioned in here to hook city water to it and turn the pump off. Been working fine since.

my slip neighbor had the same issue last month, I told him to connect the city water to it, and when he removed it and turned his pump back in, the valve quit leaking. Worth a shot imo

Nothing to loose by giving this a shot.
I will try this and report back.
Thanks
