Running 2000 RPM DC motor on motor shield

Hi,

New to electronics and Arduino, currently working on a university project.
We are making an autonomous watercraft.

I want to use the Adafruit motor shield v2 to run (2) DC motors.
Motor specs according to seller are as follows:

Model: 3674.
KV(RPM/V): 2250KV.
Watts: 1800W,Max voltage: <22.2V.
Max Amps: 80A.
Shaft diameter: 5mm.
Connector: 4.0mm gold plug.
Recommend battery: 2S-5S.
Recommend model: 1/8 RC Car,Boat .

Adafruit website says: "the H-bridge chip is not meant for driving continuous loads over 1.2A or motors that peak over 3A, so this is for small motors."

I'm wondering however if thats means i can't run the above motors "max amps: 80A" with my shield?
If yes, is there an aternative?

Thank you guys...really struggling over here.

You are correct. You can't power a 80A motor with the Adafruit shield.

If you provide a link to the motor you're using it will be easier for people to suggest an appropriate controller.

How will the motors be used to propel your watercraft? Do you need to reverse the motors?

That's a very powerful motor for an R/C car/boat - you would use a suitably rated ESC to drive it.
Does it have two wires or three?

Googling 3674 returns results which suggests it is a 3-phase brushless motor so you will need a driver designed for BLDC operation.
