I installed a new transducer just forward of the port 671 Covington in my 41' 19867 Hatteras convertible. After most of a day with help from a friend we were unable to run the cable through the existing cable run from the starboard side of the conole on the bridge to the starboard aft corner of the engine room. The harness, steering bundle, control cables completely filled race. I reviewed the schematics in my owners manual to look for an alternate route for the cable. Any help from 41 or similar Hatteras boat owners who have encounteerd this would be appreciated. We tried metal, nylon and similar approaches but the bundle fills the race and the cable ties seem to seal the deal.
