I've got a 55lb 54inch Xi5 on my boat and definitely recommend it. Its still early days as I've only had it a couple of months,
Anchor mode works very well even in wind and current and the Jog mode is a great feature. Battery life seems pretty good, I replaced an old Watersnake with foot control and the Xi5 remote is a lot better to use especially fishing one-up where I tend to wander around the boat a lot more.
I weighed it up against the Minn Kota, I suspect they are both good motors however there was quite a few lures difference in the price.
