Perfectly compatible with the HOBBYWING SeaKing V4 series ESCs for better compatibility and excellent control performance.
Specifically shaped cooling vents in the case, and a machined, polished water-cooling jacket for maximum flow and heat transfer.
Two KV options (1700KV / 2100KV) to suit different propeller setups.
Premium materials, built to last: high-hardness CNC aluminum housing, premium-brand high-quality bearings, ultra-thin silicon steel laminations, high-temperature oxygen-free copper wire, high-temperature explosion-proof rotor and high-toughness alloy output shaft.

Water-cooling tubing connected to the boat's cooling system (the motor must be water-cooled)

Comments:

Make sure the water-cooling pipes are connected reliably - running without cooling will overheat and damage the motor.
Stop using the motor if it exceeds 100 deg C / 212 deg F; high temperature weakens the rotor and can damage the motor.
The three motor wires can be connected to the ESC in any order. To reverse rotation, swap any two motor wires or change the ESC's Motor Rotation setting.
