Ok folks, THanks for the replys, but I must not be asking the correct question or the question correctly. I have read and read a lot threads on here and I did learn a few of the things you have mentioned. I am aware of the down falls of the us2 and also that you can not use it with SI. I also appreciate the suggestion to just use the factory TD.

Maybe I should put it this way. Forget that I am going to use a Fish finder at all.

What I am trying to ask is on the bottom of the Minn kota Terrova with US2 with I pilot. At the bottom of the drive motor is the TD still sticking out the bottom, somewhat like a second skag, or is the TD mounted inside the motor housing, so that the only thing on the bottom, or outside the motor housing is the skag? I think that it is inside now but I havent been able to confirm it.

Thanks for the help and I hope I explained it better.
