Teri,
If it isn't line behind the prop....
It's either the switch or the armature.
Switch is relatively easy to fix and inexpensive....you can do it yourself.
The armature is another story.
However, being an '08, it should still be under warranty.
Get it fixed, get it sold then put the MK on there and be done with it.
As an Autherized Service Venter for Minn Kota, we get far more calls to repair Motorguides....go figure. :wacko:
