I will be replacing the transducer on my 2000 272 as soon as it arrives in the mail. I had my face stuffed in the bilge today removing the old transducer and saw that there are 2 conduits which go from the starboard side access hatch in the aft berth to just in front of the battery platform. It looked like there was plenty of space in these conduits. If you use a metal fish tape, be sure to tape the hook really well so that you don't hook anything in your travels, I have the luxury of using the old transducer cable as a pull string.
