Questions on Controllable Koralias

[Funkmotor]

For anyone that's bought themselves a controllable Koralia:

1. How many connections are on the plug that comes off the pump?  What kind of pump(s) do you have?  (Different pumps could have different connectors.)
2. Do you have to tell the controller what type of pump is connected to each port...using a switch or other?
3. When the pumps are in their "off" cycle, do they completely stop spinning?  (I don't think so.)
4. When the pumps switch on, is it correct that they begin spinning in the correct direction immediately?  (No clicking at all?)
5. On the normal Koralias there is a shaft through the middle of the prop all the way to the front of the pump - do the controllables have this or is there no exposed shaft in front of the prop?  (I can't see one in any pictures I can find, but I think it must be there.)

Thanks much for any replies.
