Have you tried using the footpedal to see if there was a problem with remote?You can google this issue and then get a cheat sheet for future use.They are great motors,but can be frustrating when stuff happens.Also condition of batteries is key.These newer units hate low voltage.
Thanks a bunch for your reply. My ulterra did not come with a foot pedal I use it pretty much for offshore fishing. I checked the batteries as well and reset them by unhooking the positive. Everything seems to be solid with the batteries I also have a lithium battery which seems to be pretty solid as well. Not sure if my son accidentally reset the ulterra when we were out yesterday. I asked him to press the power button to turn it off and I think he held it down for a while I’m not sure if he reset it? but it seemed that the problem started shortly after that.
