M/K Ulterra over correcting on spotlock

[ShellbackCVA59]

I have a new to me boat with an Ulterra 112# trolling motor and it's on a Lund 1800 Alaskan. With a pretty good breeze, on spotlock, the motor kept over correcting. It would turn to the left to correct, but use a very high thrust, then over shoot the spotlock point and turn right with high thrust. Over and over again. Is there a way to correct that? Thanks, Ron

Turn the offset down to -2

Boat scale

OK, So is this on the Link remote? Settings, boat scale, -2?

Good place to start, but your boat may behave better at a different setting

Thanks guys. At least I know where to start.

With a stiff breeze, things like the position of the outboard to one side or the other will make it hard to hold the boat in position. Swinging the boat broadside to the wind will push the boat hard and overcome what the motor is trying to do. Wave action can also play a roll especially if the prop is breaking the surface now and then. There are limits to the ability of Spotlock. The boat scale definitely can cause overcompensation for sure, but I find most of the issues I have is in calm waters with boat scale.

Shellback not sure if you got the problem fixed but it sounds as though you have a Gen 1 Ulterra which is the motor without the puck up front that gives the trolling motor a better GPS lock. All the new MinnKota’s have this. I had the Gen 1 and switched to the new model Ulterra and it’s night and day difference. Hope you got it figured out. Glenn

To the best of my knowledge, the motor was bought in 2019. It does have the GPS puck. I bought the boat used, so I don't know if it was set up properly or not. Haven't had it out to see how it responds with the new settings yet. will post when i do.

Get used to it. I have a newer 80 Ulterra on my 17 Alumacraft and it’s very good one day and worthy of a BUI stop the next. I really wanted to like the motor but the spot lock is better than my 2012 Terrova on it’s good days but much worse than the 2012 on its bad days. The Terrova sucked on spotlock but at least it consistently sucked so I knew it’s limitations and how to improve it. The boat scale will definitely help the overshooting and jerky movements but it won’t fix its wandering ways. Minnkota has a bevy of reasons why it doesn’t work such as voltage, poor gps coverage, conditions etc. I don’t have time for their bs. The only “real” ASC in So Cal is horribly backed up so I’ll just get another. My fishing buddy just bought a new xi5 based on my Ulterras performance while fishing with me. Absolutely amazing spotlock. The head doesn’t even turn. Wayyyy quieter and a miser on the batteries.. I’ll miss the auto stow/ deploy but can’t wait to get one. Good luck with yours. The word on the street is it’s 50/50 you get a good one.

The word on who’s street? Yours? I have not seen or heard a word about GPS problems with ipilot except in your posts. Most issues are in setup. JMO Bob

Every time I take my boat out I have to change the boat scale from +2 to -2. For some reason my Ultrex wont save this setting to memory.

Hate to sound totally stupid, but where do you find this “boat scale”?
have a 24v Ultrex that overcorrects badly in current.
thanks!

If you have iPilot LINK Bluetooth= Scroll down to Systems, select, and then scroll down to Boat Scale, then down to -2.
Page 71 and 72------i-Pilot Link Owner's Manual (widen.net)

Be careful not to change the setting when exiting or you will be back where you started.
Double check the setting by going through the menu again.
I find it easier to turn the hand remote power off instead of exiting so I don't change the setting with the touchy touch screen.

Next time you make a change, try using just the exposed/raised home button rather than the touch screen.

As Wayne mentioned, touchy touch screen.

I would like to see them change it to a two tap/touch input.

Do you have a Heading Sensor installed? Just curious, thks
