Help replacing an odd pump power cable

[MainePool207]

I need to find a replacement cable for my pool's pump. There's a pretty solid chance that who ever wired this may have performed some splicing on cables/plugs. It's 15A/ 125V, and I think I can get away with just replacing the plug itself (the cable is 15 feet in length or so). The ground on the plug is flopping everywhere and likely explains my short. I just can't identify the TYPE of plug. It's not a standard pool cable that I can find at my pool store. They suggested I talk with an electrician. I'm looking at plug charts online and I can't find it. The horizontal prong looks manually twisted.

As you can see below, I've been trying to pull the screws out but they are very rusty. The top picture IS upside down, but just so that the amperage could be read.

Is this an unusual plug? Was this manually added over a traditional pool power plug? Any help would be greatly appreciated so I can get the filter running again.

Very common. Take it to a Home Depot or good hardware store and they will have one. That is not a weather-proof plug. Be sure it is in a "wet-in-use" cover to replace what you have now.

What is odd is you have a 20A 125V receptacle (outlet) and a plug labeled that it's a 15A 125V that should mate without and issue. But the Neutral blade on the plug is twisted 90°.

Does your pump run one 125V or 250V? Also what is the current rating at 125V and 250V? A 5-15 plug may work, but a 5-20 might be the correct plug if the current draw of the pump is high enough.

If you pump is running at 250V then install a new receptacle 6-15 or 6-20 and install the proper plug too 6-15 or 6-20.

I would install a new outlet since that one looks like it's see a few arcs.

Yeah. It's sort of started all kinds of questions for me.

Thank you both for responding. I went back and looked at the WaterAce documentation... and I'm pretty sure I need a 20A plug NOT a 15A... and it's at 125V (so that's good). The label is worn off so I'm trying to make educated guesses based on what little documentation I have.
