Cool  ESC first then motor as my usual way. Because motor price is cheaper than ESC

High KV value the less the motor torque is. Boat require high troque for starting even running as this boat has no gear box. however jet-propelled type is require more energy then propeller shaft type.

Hope play together with you guys under this topic.
