New Terrova

Attachment 366526
Ok I got to put the new tm in the water today, and of course this thing is way smarter than I am. This first picture is about the boat scale. I have an older model 17.5’ bass tracker. What do I need to put the scale on?

These other two pictures are when I had to do the sensor offset. I’m not sure what the 18 is? That’s the number I got when I had it pointing forward. The second picture that says it’s too large is when it was parallel with the boat.

I don’t have the answer but I’m sure someone from here could help.

I appreciate that, but they are closed. Was trying to figure it out while I don’t have anything to do.

The 18 is the degrees of offset between the trolling motor and the heading sensor ( the white gps puck)

Is that good or bad? Anything I need to do?

Boat scale. Start at 0
Adjust up or down depending on boat weight and wind.
Neg. number is a slower reaction by motor
Pos. number is a faster reaction by motor.


Decrease the offset number.

1st make sure you are using the screws supplied by manuf.

Loosen the screws and slide a piece of duct tape under the front edge from left to right.

Make a pencil mark on the puck and the tape.

Tighten 1 screw and remove the 2nd screw.

Test if you can move the puck with some effort. You don't want the puck too loose or it may move by itself.

Move the puck a few degrees left or right. Rerun calibration.

If the offset is larger, wrong way.

If the offset decreases, this is correct direction and keep adjusting until you get about 5 degrees offset and press set button and mark the tape with the pencil.
This is the new puck location.

Tmotor is now calibrated to forward boat direction.

Redrill second hole and reinstall 2nd screw.

If the 1st hole for the 2nd screw is too close to the new location, start over with a new location but don't drill the 2nd hole until calibrated.

With the lighter alum boat you will likely want a -1 or -2. I use -2.

If you feel the urge to try +2 then I recommend you hold on because when it changes direction to adjust on spot lock you might find yourself getting wet. Lol.

I have an aluminum 20 foot center console and I run my scale on -1. You might have to run it on -2.

Thanks guys, I think I have it figured out.

I'm getting a Terrova tomorrow and I just read this thread.
The first item is boat scale and from what I gather, is that a setting that allows you to adjust how forceful the TM will be when you are on spotlock? If not what is that function for?

To the OP did you get a 12v or 24v TM for your Tracker?

Crappiemax, that's correct. When you run it lower on the scale the less responsive the motor is - slower to ramp up to high speed. Without this a lighter boat will keep moving past the spot locked location, like mine.

This pre-2017 Terrova didn't have this adjustment and my uncle fights the motor more than the wind at times.

I got the 12 V and have used it three times since I have had it and it has plenty of power for my boat. Now if you’re going to be fishing in 10+ wins all day you will probably need two batteries. I used it Monday in 13+winds and the spotlight held me in about a 3-5’ area which I consider really good! I also put the boat scale on 0 which I think held it closer better.

If you had changed it to +1 or +2 it probably would have held 0-3ft.

Wind up.......scale up
Wind down...scale down

Yea I thought about doing that, but at the time I wasn’t too familiar with what it did.

You will get used to it.

No matter if I am in the glass or the tin boat(different weights and profiles), I always start at 0 scale for the day.

Similar to adjusting the graph display first thing in the morning to the water conditions.

At the first spot lock I just look at the remote and see how close the Tmotor is to the target and then adjust accordingly.

Not uncommon to change the boat scale throughout the day according to the wind conditions.

Enjoy the new Tmotor.

Thank You. I have the same size boat and I opted for the 12v also and I already have 2 batteries since I fish a few TM only lakes.
Thanks for mentioning that setting it gives me a good place to start.
