First time out with my new Ultrex started out great with everything working perfect. Spot lock is the best thing ever to happen to a trolling motor, stress free fishing in the wind when wanting to stay on a point and just fish. About half way through the first day with little to no breeze and with spot lock engaged the motor would have to go all the way to stop to the left and some times all the way to the right stop to stay on the spot, no problem working great. Then the spot lock started tuning off when it hit the stop to the right but never to the left. Not all the time but got more frequent as the 3 days of fishing went on. Thought an easy adjustment just call Minn Kota and they will walk me through it and back on the lake, wrong. Called and told a rep what was happening and he said to send it back no adjustment fix, bummer with out a trolling motor until I can get it back, wrong again. They are shipping out a new motor and when I get it installed to send them the old motor. Minn Kota is covering the shipping both ways. Bummer to have to install again but no problem as I am some what good at it now that the one I have now has been on and off the boat a few times. Customer service at Minn Kota I could ask for nothing more.
