First time out with my friend testing new Xi5. Anchor mode held boat within 2 feet of spot in wind 8-12 mph and gusting to 20. Motor turns fast and is very quiet with no vibration. Motor head and shaft is sturdy and appears well built. Does everything described. Down side is remote hand control has no display where MKs does have display. MG function display is on base of motor bracket. MG stores and track more routes than MK
Lot of money for either brand but I was very impressed with the anchor mode holding so close and how little power was pulled after 7 hours of almost constant use. MGs is a new model but the technology isn't new. I think either brand would be great and is a matter of personal choice.
