DC Motor needs more V, still control via Arduino

[bucc5062]

I started this project to turn an RC boat into an autonomous drone for in my pool. I bought the arduino, an L298N DC Bridge, various other stuff and put it all together following a basic diagram for controlling a DC motor.

However, the boat's battery is 9V and I feel the motor(s) on the boat requires at least 7V and when I try running the program to control one, I hear it click (softly) like it is trying, but there is not enough energy to turn the motor? I know the motor works for I can run it off a larger battery direct. The original battery on the boat is 9v so my question is,

is there a way to get 9/7 volts to the motors and still have the arduino control their action (on,off,reverse)
the link I used to get started is this:

I put a tester on the two outpins (1&2) and I did see voltage change with a max of 5.6 to -5.6 so the program and controller do work. These are fairly beefy motors and I am good with having a separate power supply to the arduino/L298N, but would I need something to "switch on/off/reverse power to the motors from their power supply.

I have an UNO, but would I maybe need a controller that can handle more power?

You might post your proposed schematic,not a frizzy thing. Also post links to each of the hardware devices such as the motors (These are fairly beefy motors). I would suggest looking for another H-Bridge driver teh L298N is an old and inefficient device that as you found out cost you lots of volts to the motor.

What battery are you using ? PP3 ?

RC motors are usually much higher current than a meek little L298 can handle - 10 to 30A sort of range is what I'd be expect it to draw - a suitable ESC will be needed
(like the one the boat came with?)

However it all depends on how big the boat is!
