For customers convenience, we made 10mm diameter screw on the top of the shaft, so you can install the propeller directly, and to match with the motor, we made a suitable propeller as following:

How to Ensure Its Waterproof Performance:

To make sure its waterproof, every joint surface of the motor exterior parts, including top/bottom cover and motor case are seamless structures, wiring port and wiring terminals, a static sealing mechanism is arranged between the joint surface of the fastening bolt and the bolt hole, and a dynamic sealing mechanism is arranged between the motor shaft and the shaft hole.

The components on the outer surface of the motor are made of corrosion-resistant materials or are provided with an anti-corrosion layer. Since the gaps or passages that may exist inside and outside the waterproof motor are blocked by the sealing mechanism, a reliable waterproof effect can be obtained, and even if the water is poured for a long time, the water will be fully blocked inside water, and the short circuit failure occurs.

To make sure the waterproof, we've tested the motor underwater for over 12 hours before released:

And we recorded some test data as following:
