I have 4 798's and I want to hook them up all on my ranger 
I want to hook two on the bow and 2 on the console. I want to have all of them hooked into an interlink 
can I do this? 
what all do I need to do this. 
I know I need the interlink and a transducer for the trolling motor. 
how and what Else should I need to get this accomplished. 
I was trying to trade two for a 1197 or 998 with cash but no one was interested so I have to make due with what I have. 
any help will be much appreciated..
I want to be able to run Side Image and chartplotter on one and sonar and downlooking on other at same time if possible.  
thanks
