I'm interested to hear how you go with the 1.160 updates to the Minnkota and remote.
The 1.160 firmware appears to be designed to fix a bug in the remote where the battery indicator never shows a 100% charge.
It actually introduced a couple of absolute ripper of bugs into my iPilot link motor.
In very light tidal and wind conditions the Spot Lock will lose the plot and just switch itself off. This is manifested by the motor rotating about 90 degree's clockwise and then about 90 degree's counter-clockwise, the propellor icon on the remote flashes and the Spot Lock switches itself off.
Spot Lock will work fine if it has a wind or a tide or both to push against continuously.
I tested mine in a raging run out tide the Minnkota had no hope of beating but it still attempted to hold the Spot Lock despite it steadily losing ground to the tidal flow.
The second one just about put my boat up on a rock breakwall one afternoon and again involves Spot Lock.
When the boat drifts off the Spot Lock mark (which it will do and I have no problems with this) and comes back toward the mark one of two things happens.
If the motor speed reduces sufficiently to allow the bow of the boat to drift slightly off line and require a port or starboard correction all will work fine and the Spot Lock will be maintained.
If the boat continues on Exactly the same heading over the Spot Lock mark it will continue on this heading into the wild blue yonder.
Basically the remote will show the current heading and it will maintain this exact heading, the distance to Spot Lock mark on the remote will increase as you overshoot the mark and the motor speed will increase to 10 to attempt to reduce the distance to the mark. The motor doesn't appear to be able to reverse its course but most certainly can increase its speed.
In my case once straight at a breakwall, once straight out into a shipping channel with a bulk carrier coming into port and once it tried to send me out of the harbour and onward to New Zealand.
I've never let it go long enough to find out if Spot Lock gives up or just keeps going until the battery goes flat!
So yeah, I'm a big fan of Ver 1.160 in the Minnkota.
Surely I'm not the only one in the world that has seen these two Spot Lock "features"
