Folks, the thread title says it all. I know this topic has been covered in detail but I have tried every suggested remedy. No dice, the dang thing loses Spotlock constantly. 2020 Ultrex 112 45" with three brand-new batteries and it has been used twice. Meticulous installation, the pedal has been indexed as level as a pool table, absolutely no obstructions under the pedal, pedal raised up in tray to allow full front-down travel, GPS puck has a clear view of the sky, puck paired with motor, heading sensor calibrated 3x and sensor offset performed etc etc etc. Today I was out on a lake with Spot Lock on....the pedal was level, no obstructions etc and it simply went out of spotlock. Another instance, the boat was holding reasonably steady when suddenly the motor did a 180, pinned the pedal to the rear and it went out of spotlock. It does both of these repeatedly.
This is really a bummer because I had a 2018 Ultrex on a river jet boat and it was magnificent. Hit spotlock and it would hold the boat in all but the worst current, no more heaving and retrieving a 30lb river anchor. Any words of wisdom would be appreciated, thanks.
