Does anyone have a transom mounted transducer on their boat? If so, how did you run the connecting wire through the transom with the swim platform above it? I have a 230 Select and I have tried the shoot through the hull transducer and that didn't work. I would like to mount the transducer in order to get water depth info to my chart plotter/sonar. I'm just concerned about drilling a hole through the transom. Thanks.
