I'm having the same problem with my 1996 3300.  I have my Furuno cable and two radio antenna cables all going through the same extremely small hole at the gunwale.  It appears that the radar arch has a tube as part of the construction and the cables must pass through that tube.  I was going to pull my signal cable out and send it back to Furuno to get it repaired but I'm not sure that's even feasible at this point.  I may have to leave it for dead and pull it out from the top of the arch with a tie line to it, then get an all new radar system.  Really sucks.
