Yes and No, but I wouldn't try it. Read on!
Theoretically you should be able to run the motor it just won't be as powerful.
Now understand electricity, when voltage drops, current rises, and vise versa.
Say you have a 36V system and it draws 10 amps.
If you drop the voltage in half 18V, the current draw will double to 20 amps.
So in your case you would be dropping the votage by 1/3 your current draw would go up to around 17amps.
Now here is where the problem is, higher current = more heat, and I don't know if the added heat will cause damage to your trolling motor.
Like I said yes and no, but I wouldn't try it.
What is up with the wires, why can't you run 36V?
