transducer line mount.

[yaky yak]

I installed my transducer on my OK endeavor(same as a prowler)thou a rear scrubber hole make for this. I used the transducer that came with my humming bird 170, grinding off the existing mounts to make it flush and epoxying it in there. That worked fine. Now where do I run the cable into the hull from back there? I bought rubber stoppers, drilled them and split them for the cable to fit snug in, now I just need to drill the holes, but where? Nowhere looks appealing. Thank for any advice. Yaky yak
