I've had the ulterra for 5 years, let me say it has not worked more than it has. Last year Ryan at Chip's Marine in Sullivan Illinois talked to minnkota and they agreed to basically rebuilt my entire unit as it has never been right since new. Since the rebuild it has been working well, I have not used it a lot but when I do I would like for it to work. With my experience I could not recommend an ulterra to anyone
