For hull penetrations, going out the back plate is probably going to be logistically easier. A curved section of identical material would be slightly stronger, but harder to seal against. You can make your own pass throughs, or buy one of the various waterproof connector sets. I'm using a set of Lemo waterproof connectors for mine. I don't have the endcaps to install them into yet though heh.
I think you are right, I will buy a couple of water proof connectors one to connect the motor wires in to the housing then another to the tether.
