Minn Kota head unit not waterproof???

[The Mad Cat]

Recently a good friend had a problem with a new Terrova and took it back to the dealer. They fixed it. He asked what the problem was and they said water had got into the head unit and damaged the circuit board, but they have now sealed it to make it waterproof as they are not waterproof from the factory, could this be right?
I'm going to check mine.

I have been told that nothing is sealed on these motors.
