7. The motor


The selection of motor is the trickiest part because we need to make sure it waterproof and can handle the water pressure. We do a lot of research and come out with a solution. We buy submersible water pump. In the water pump, there are motor that help the system to operate. And of course it already waterproof. so it will save our time making DYI waterproof motor. We brought pump from Blidge that have pump power up to 1000 gallon per hour. The best part is, this motor is running in high torque, means that resistant from the water will be no problem to this motor. But before we start to use this motor, we need to take out the cover that hold the motor. When we take it out, we attach the shaft with the propeller that we already bought.
