[TG] [TG11] Multiple issues with new instrument package

[Waltdrechsler]

We have a speed transducer connected directly to the i50. It is a new unit that came with the sailing package. Not sure if I am reading zeros or dashes but I believe they are zeros. I will check this. If dashes I will run the multimeter test. If they are zeros, what is my next step?
The depth gauge seems to work at lower speeds but it seems to lock often on the "last" It does not always want to reset even with a breaker reset.
We have a fin keel that does have a bit of a flare at the bottom. How do I get around this?
ES98 - I will reset the sonar and give that a shot.
