Hello

I bought an electric outboard
motor to my rowing boat.
Motor is made in Russia. As
you all can guess the thrust
isn´t wery good. It´s poor.
Motor works normally with 12v.
battery, and I was thinking if
it can handle two
12v. batteries in series.
Voltage and current would then
rise to double.
If the motor doesn´t break it
will go faster, right?
What do you think?
Can the motor handle the extra
12volts or will it break?

thanks.
