Boat Compatibility:

Recommended for RC boats between 27” – 40” (550mm – 1000mm) depending on motor choice. Due to varying hull designs and motors, we advise confirming compatibility before purchase. While IP67-rated, this ESC is not designed for full submersion. Ensure proper installation to prevent prolonged exposure to water.

The SeaKing 160A HV V4 is an excellent choice for enthusiasts looking for power, efficiency, and durability in their builds. It pairs perfectly with setups like our own Maverick Jetboat, the M-Jet 35 pump, and the Ragnarok, delivering smooth acceleration and reliable performance in extreme conditions.
