Why not use a standpipe with a u-trap at the top. That's probably the easiest way to run multiple wires through the deck and prevent water intrusion. A 1-1/2" pipe will handle a lot of cables fairly easily, and most connectors would fit through it as well.

Exactly what I was talking about.

I use a "swan neck" fitting. I had mine custom made, it really makes things easy and no water intrusion is possible.

Looks like this:

The tube projects for about 1" downward from the flange, which makes it sit pretty strongly in the deck.

Looks like an interesting solution, but you really should have something over the top lip of the tube to protect the cables from the metal edge.

I use this solution called cableport.

I like this solution as it is easy to add more cables later and you can pass plugs through the opening.

Thanks for clarifying.. that is a nice design. How much was it??

It's not obvious looking at the posted pictures but the edge on top of the tube is well rounded as you can see on this illustration.
