3rd Motorguide Fail in 15 months

[T-Boo]

My Motorguide R3 transom mount failed me yesterday while fishing. Just failed to work all of a sudden.
This is the third Motorguide motor I have had crap out on me in 15 months. They seem to have no problem backing up their warranty and have been very accommodating, but the physical product hasn't proven to be very reliable.
For the record, I am as gentle as possible on my equipment and do what I can to baby it.
Has anyone else played this game with Motorguide? When the motors work, they work well. It's the only brand I've ever used for the past 20 years.
