Big Motors > SeaDrive (Underwater/Industrial)
The F3130 170KV waterproof brushless motor is designed for low-noise aquatic applications, including fish tank circulation systems, RC boat propulsion, and miniature submarine drives. Featuring IP68-rated epoxy potting and ultra-compact design, it delivers efficient power output with minimal vibration for sensitive underwater environments.
