I just installed a XI5 on my boat. Got the 24v 60in because it was what they had in Stock at the time. I had one on my last boat and had a hdi ducer on it doing the coil method. Worked but not astetically pleasing. This new one didn't not have pinpoint gps installed ( got that model so it would not have the built in ducer), so got the gps and installed it today. Looking at the head unit there is just 2 wire that run down the shaft to the motor. And there is plenty of room to run a ducer cable inside. Got me thinking. What if I cut the HDI ducer 12-24 in from the blue connector. Then drill a small hole in the xi5 shaft above the motor and below what would interfere with closing the motor. Then I could run the wire internally and come out another small drill hole in the head. Then just solder the ducer cable and be done. I know I would have to seal the drill hole on the shaft so water does not enter the motor. But it seems do able. Any thoughts? And I know it would void warranty, but it's just a thought I'm rolling around my brain.
