I just purchased a used Xpress x18 2002 modle with a Mercury 150 xr6 2003 model and I am trying to figure out how I hook up a depth finder on the console. It has the lowrance depth finder, circle one, in the dash already, but I am more intersted in hooking up my lowrance to know the temp. There is already a transducer on the back for the stock finder already installed. Is there anyway I can hook my depth finder up with this transducer???? All i have is the depth finder, no cables or anything. How can I accomplish this task? Any help appriciated!!!
