Create additional slot in terrova shaft for transducer cable

[lifeisfun]

They didn't think about because it's not recommended to run and external transducer on the Terrova or Ulterra -- howeve some do and have managed to come up with devices allowing them to do it. The lift assist is part of the turning mechanism, so don't remove it. The shaft is made in such a way as to be the same thickness all the way around, in other words, the square slot for the lift assist spring is not milled in the shaft. When you go to mill/rout a groove, there is a good chance you will go through the shaft. As you said, it would not be warrantied and on the Terrova, you don't replace a shaft -- you replace a shaft / motor center section for around $200.00.

Thanks John!
That sucks :(
I used external transducer on the older version with awesome results.
The new v2 I got with US2 is POS , no matter what I do the upper 2.5' is covered with disturbance.
No difference if the motor is on or off. Connecting external transducer the image is perfect.
It just bothers me when fishing shallow water since it clutters the whole display.
