Description of Underwater Propulsion CW and CCW:

Marine propellers are usually classified into two types, left-hand and right-hand, known as CW and CCW, respectively.
CW is an abbreviation for Clockwise, which means a propeller that rotates clockwise, also known as a right-handed propeller.
When a ship's propeller rotates, the leading edge of the propeller blade is on the right and the trailing edge is on the left when
 viewed from the side, driving the water in the same direction as the rotation. A starboard propeller is usually mounted on the
left side of the boat, i.e. port side.
CCW stands for counterclockwise and indicates a propeller that rotates counterclockwise, also known as a left-handed propeller.
When a ship's propeller rotates, the leading edge of the propeller blade is on the left side and the trailing edge is on the right
side when viewed from the side, pushing the water flow in the direction opposite to the direction of rotation. The port propeller
is usually installed on the right side of the boat, i.e. the starboard side of the boat.
Installing the left and right propellers on both sides of the boat balances the propulsion and side thrust, making the boat more
stable and steady.
CW propellers CCW propellers
 produce forward thrust when rotating clockwise
and backward thrust when rotating counterclockwise;
produce forward thrust when rotating counterclockwise
and backward thrust when rotating clockwise;

How can I use a Raspberry Pi 4B to send a PWM signal to an ESC to control an underwater thruster?

Example code:
import pigpio
import time

pi = pigpio.pi() #create pigpio object
LED_PIN = 18 # Define the GPIO port to which the LED is connected.
PWM_FREQUENCY = 50 #define the PWM frequency in Hz
PWM_range = 1000
PWM_DUTYCYCLE = 0 # Define PWM duty cycle, value range 0 (2) 55,
pi.set_mode(LED_PIN, pigpio.OUTPUT) #Set the GPIO port to output mode
pi.set_PWM_frequency(LED_PIN, PWM_FREQUENCY) #set PWM frequency
pi.set_PWM_range(LED_PIN, PWM_range) # set range 1000

pi.set_PWM_dutycycle(LED_PIN, 75) # set PWM duty cycle 75/1000=7.5 per cent
time.sleep(3) # delay 3s unlock successful

pi.set_PWM_dutycycle(LED_PIN, 100)
# Positive rotation 7.5%-10% duty cycle, the larger the duty cycle, the faster the positive rotation speed

pi.set_PWM_dutycycle(LED_PIN, 60)
# Reverse The closer the duty cycle is to 5%, the faster the reversal speed is

pi.set_PWM_dutycycle(LED_PIN, 75)
# Duty cycle

Very good unterwater Thruster!

I am a Swiss High-Scool Student and as my final project, i built a ROV. For this Purpose I ordered 4 of the U2 Mini Thrusters and they worked Very well and have a lot of Thrust. (Even too much for me, i had to power them with a lower pwm Signal than the Maximum)

Also the Quality of the Product seems very good and I'm Happy with the Product (Despite they where quite expensive for my Budget.)

First I didn't know whether I could thrust the website of Apisqueen, so after a short Chat with Apisqueen, I ordered the Thrusters on Aliexpress where I have some Inscurances and a Money Back Guarantee. But If I had to buy a second time, I would buy them directly from the Apisqueen website.
