So, I have a newly purchased 2005 320DA. When I delivered it to its new summer slip upon purchasing, I realized that I did not have a shore power adapter. The marina let me borrow a y adapter but I really need to get my own so my question is what do I need? I see a lot of numbers listed out there as far as 30/50 amps and 125/250volts go. I also see different amp male and female numbers The shore power is 50 amp and im assuming my 320 is 30 amp. So what exactly do I need? Thanks!!

If your home dock has a 50amp connector on the pedestal that's what you need or at least some adapters. I believe your 320 may be similar to my 340 and should have two 30amp inputs in the after storage compartment.
If this is correct you will need a 50A cable with a 50A to 2x30A Y Connector. Also keep in mind if you are going to other docks many for our size boats will have 30Amp service so you may want to have a 30A cable with a 30A to 2x30A Y for those situations.
There are many alternative plans to this so, think about it and plan it out - this can get very expensive real fast. If all this is new to you then you may want to try to pickup some good used cables. Just look out for frayed cables or burnt ends.
I actually have a set of cables that stay at the dock and a set that I travel with along with a couple of extra cables and adapters as you never know what you will run into when your out and when traveling you should check with the dockmaster to see what type of power and connections are available.

Thanks for the response, Kevin. All my marinas dockmaster told me was that I would need a 50 125/250. Also, the only thing I know is that I have just one shore power cord plugged into one shore power connected in the aft storage compartment. As far as I know it’s 30 amp and as far as I know that’s all I need because i haven’t had any problems. But now that you bring it up I feel like I may have seen a second 30 amp connecter in my aft storage locker. So, I really have no idea what I have or need. My dock neighbor actually has the exact same boat so I guess I will ask them when I see them this weekend. I never thought to ask because whatever I have seems to be working just fine and doing it’s job.

I had to purchase a 50 A Male to (2) 30A Female Y adaptor for the temporary marina we're in. They are about $200. I've attached the spec sheet for it. Sounds like what you will need.
Keep in mind you will still need (2) 30A shore power cords to go from this to the boat. This just splits a single 50A service into 2 30A outlets. and is attached at the dock.
I'd have to confirm, but I don't think I'll need this once we move to the lake, and I may be selling it.

I would think it is only a 30A - Your owner manual will detail all this stuff.
If you don't have one get your Hull ID and register at Sea Ray and download it.
You may also have a TV/Cable hookup in there too. Also since it is not a new boat you'll never know what you will find added.
That's my suggestion! Its a great way to get answers, meet people and make friends.

I think this may be what you'll need...BUT, you need to make sure the Male & Female ends are the right ones for your boat and pedestal and the connector blades are all the right ones. Lastly, also make sure that 25' of cable is enough. For many boats, the longer 50' length is required.
I recommend you take a picture of the dock connection and the boat connection and then match it all up to the great MARINCO diagrams from this Amazon link below. That way you'll know what you need and can begin asking around. As someone else stated (and as you'll see in this link) these adapters can be crazy expensive. Click on the second photo for each adapter and you'll see the configuration shown for each end.

Good idea about taking the picture.
@rh320 Why don't you take pictures of your pedestal and the plug on the boat and post it here? There's less chance for confusion and we can give you the right advice.

At our marina, if you tell the office what type of power you need, they will change out the pedestal to accommodate without having to buy adapter cables. If it is single 50A on the pedestal and you need single or dual 30A power, ask them to change it out for you...
Im not sure I need a y adaptor? So, the boat came with a 30amp cord and thats it. I assume that its just a single 30 amp power and that I dont need a y adapter? My dock neighbor has the exact same boat just a year newer so ill have to talk to him. Just thought I would ask on here since I really wanted to get this ordered!
I will do that if my slip neighbor with the exact same boat isnt there this weekend. If he is then I guess ill just ask him. I was just hoping I could get this ordered and here by the weekend!
I'll have to ask! I never would have thought that they would swap the pedestal like that.

Kevin’s advice is solid. Try to get the manuals for your boat. While your at it, try to get them for every system, electronics, and accessories too.
I got lucky and got the “owners packet” with this boat, but I was able to locate just about every manual online and download them to iBooks on my iPad so I don’t have to keep the owners suitcase on the boat.
I’m guessing, but can’t be sure, that you have a single AC/Heat unit and likely have a single 30 amp 125 shore power inlet on your boat.
If you plugged in one cord and all the 110 breakers in your panel got power then you only have one inlet.
If that’s the case, you’ll likely wind up needing several adapters if you travel to other docks anyway.
I had a single 30/125 inlet (which was male) on my old 300 and offhand I remember keeping adapters to plug in to 15 amp, 50/125, and 50/250 female shorepower receptacles on that boat.
Boat end of the adapters themselves should be female to attach to the male inlet on your boat, and dock ends of the adapters should be male to plug in to female receptacles.
Having a home dock cord and a travel cord is very convenient too.
If you have two 30 amp inlets on your boat, like I do now, then you start to need to add an assortment of Y adapters to the collection.
I’ve got a small fortune in Marinco adapters, connectors, and cords on my boat.
My buddy just picked up an 05 480 last week that has a single 50/250. He needs everything he used on his 05 420 plus now he needs reverse Y’s too.

Your 320 should have a single 30amp shore power cable, just like mine, there is another metal outlet in the locker, but it’s for cable tv and telephone, neither is really valid anymore. If you get a 50amp male to 30amp female converter (131$ first one I found), that will work. The male end will plug into the pedestal (the pedestal must be female, otherwise you can just stick your fingers in and get fried), the female end you will plug into your standard 30amp cable, then the other end of your cable, female (again for safety) plugs into the boat. I like the idea of switching out pedestals though. Typically, most pedestals I have seen have both, one 50amp, and 2-30 amp plugs, but every marina seems to be different.

When I travel, I just request a slip with 30 amp service. The one time a marina didn’t have a 30amp slip, they provided me with a 50 to 2 30amp y adaptor.
Here is link, see if the 50amp male side matches your pedestal?

I am lucky to have bought a one owner boat with all of the original manuals and booklets for everything! I will have to look to see what they say about my shore power. But I do only have one cord plugged in and I have had no problems with running any of the systems.
I am glad someone with a 320 replied. Thats exactly what I ordered! I got it on amazon and saved like 20 bucks.

Sounds like you have a single 30 amp inlet.
Not sure why you would need a Y with one inlet. I never needed one in all the years I owned my 300.
3 pigtails should cover you for anything you may come across.
The 15 amp pigtails are relatively inexpensive and may come in handy. I always kept one aboard my 300, still keep it on my 410, and used it a lot over this past winter when my boat was blocked up in a boatyard and the closest power was an outdoor 15 amp receptacle.
Beware that there are 2 kinds of 50 amp receptacles you could possibly need pigtail adapters for.
The one I’ve seen the most is 50/250.
The one I’ve seen the least is 50/125, but they are out there. The National Park Service has them in their two marinas here and if you need that adapter they charge you $7.00 a day to rent one.
