You should be able to look up the model number of you TM. They dont make one model # that uses 24v and 36v. But in any case, you certainly do NOT want to run a 24v TM at 36v. You will kill it with heat, and if it is a digital, it is possible that the higher voltage will affect the electronics.For me, the first step would be to find out exactly what your TM requires in terms of voltage (and here you luck out, in that higher voltage actually HELPS your in-boat wiring as you can carry a much higher wattage drain at the motor with a lower current drain thanks to that higher voltage. Which will actually produce less heat in the boat wiring. But in the TM internally cant live with it because it is designed with a specific voltage in mind. Once you know what your TM wants, verify that your three batteries are hooked up in series or else take a volt meter to the front of the boat to see if you see 36+ volts at the TM plug. If so, you have two choices if you dont want to get stuck somewhere with no TM. Either (a) replace the TM with a 36v unit. Which seems like gross overkill on a Sabre. I run a classic with an 80 lb Maxxum and I fish mainly rivers. I have zero problems and the only time I run at max TM speed is when I am moving from one spot to another and dont want to crank the big motor. If you decide 24v will do (and I am pretty sure it will), just remove one of the three batteries from the link, so that you have two batteries hooked + to -, and the other two unused posts (one on each batt) goes to the front of the boat via the TM wiring.If you do have a 24v TM, Id expect it to show issues sooner or later due to heat from over-voltage.2008 Pantera Classic2014 Mercury Pro XS 200
