Please help identify this port

I have a Power Vision PowerRay underwater drone that seems to have a bad port.
I am trying to locate a replacement port, but I don’t know how to identify it.
Here is a photo:

Thank you in advance for any help you can give me.

I’m not finding the part number for the Port you are looking for.

Do you have more information on that part?

It connects the Base station with the underwater drone. It might be related to underwater network connections. I can also send you a photo of the back if that might help.
Thank you,

If you can include a picture of the back and the wire gauge that would be helpful also.

Here you go.

Thank you.

I’m sorry, I’m not finding an circular connector with two different size diameter contacts like yours is showing.
