Electronic steering foot pedals are just prone to problems. A little bit of sand, a split shot, anything really can cause issues with the function of the pedal.. the micro-switches are touchy. I havent heard many problems from the remote control units because they arent rolling around on the floor in the dirt.
I dont have much against motorguide. I blew out the lower unit on one on my 2nd trip of a new motor,warranty tok care of it and I had no more problems… until shallow water and the lower untit bumped a log and bent the shaft. That I have a problem with. I have had both Motorguide and Minnkota trolling motors apart and I can tell you 1st hand the brushes are much heavier duty in Minnkota which suggest they will last much longer before replacement is needed.
The shaft on motorguide is where my issues come in. I dont go a season without running my lower unit into somthing, and the momentum of the boat keeps on pushing and bends the shaft every time. his would be a non issue when fishing over deep water, but its a huge issue spring crappie fishing, or catfishing around timber.
Minnkota on the other hand tends to break the little tilt release button(transom model) if you hit something that hard.. the piece cost $5 and takes just a few mintes to replace. I choose an easy/inexpensive fix over straitening a steel shaft.
