What is the diameter of the thruster? Overall dimensions?

External Size(mm): 101 mmx55 mmx60 mm

Could two of the thrusters be strong enough to propel a 12 foot kayak?

Sorry, this one not enough for a kayak, but we are developing bigger thruster.

What motor is used in this thruster. Is it replaceable?

Brushless dc motor with waterproofing treatment, not replaceable, but can offer motor only.

what other components are needed to make this thruster work?

For wiring: The thruster have 3 wire: Black(GND) Red(power+) Yellow(Signal).You can just connect black and red wire to a dc 12-24v power or battery. Then connect yellow and black(same with power GND) to a PWM signal.For signal, you can use Arduino or Pixhawk or any other controller that can output a 50Hz PWM. The signal should be 50Hz, and the program need to initialize every time you turn on the power: output a 2ms pwm signal then delay 2-3 seconds , then output a 1ms signal, you will here a Bi--Bi--Bi-------Bi---Bi sounds, that means power on fine and initialize done. All these process is same as RC DC motor for drone. You can also simply use a PWM signal generator.
