We have used MG Wireless 45lb Trolling motors, for quite a few years. We use two remotes and the guy in the back (me) takes over when the guy on the front, hooks up. 45lb wasn't going to cut it, so was looking for a 70-80lb thrust. Still wanted electric steer w/remotes over cable steer. I wanted something with anchor lock and sonar incorporated. It came down to MK Auto-pilot or MG Xi3/Xi5.
The Pinpoint GPS seemed to have better reviews than Auto-Pilot. MK does have much better, but this is not a "at any cost" rig out. We were also happy with our MG Wireless, so seemed like the better choice. I couldn't find a local store with either the Xi3 or Xi5 on display. The main difference I could find between the Xi3 and Xi5, was the latter came with a foot control that is optional on Xi3. I did lean toward the Xi5 for the extra 10lb of thrust, but it lost out to the additional $200 cost. Ended up ordering the Xi3 online for under $1500. This is the 70lb with sonar and gps.
Unlike the Wireless, a detachable mount does not come with it. MG has two mounts, I went for the cast aluminum one. Installation was straight forward and could reach all the bolts from the front plastic hatch cover access. The long ss bolts that came with the mounting were a pain. Probably for use on thick fiberglass boats. I ended up galling two of the six and snapping them off. Shorter ones from the H/W store fixed it.
Also ordered a second remote. The lanyard that comes with the remotes has a safety feature for easy break-away. We found that popping and dropping to the boat. A little dab of super glue fixed that.
So far, we absolutely love the anchor lock. It has worked extremely well in the current/wind we have encountered. My son will not have the excuse anymore that the fish hit while he was on the trolling motor.
We plan to try some of the other navigation features for fishing along the banks.
The only real complaint is the deployment and retracting is kind of a pain. The Wireless seems so straight forward in comparison. Maybe the Xi5 is better? Just going to deal with it, and hopefully gets easier with use.
