Cooling line question

[G-UNIT]

My cooling line enters the esc first then into the motor.
My question is, does the line enter the lowest part of the water jacket and fill it up and then out or does it enter the highest part of the jacket and run down then out, which is best.

Lowest in, highest out.

This way the air bubble gets pushed out so the jacket can fill with water.

Yep highest out as said, if you do it the opposite way round ie lowest out highest in the jacket dosnt fill to the top of the jacket as it starts coming out when the water level reaches the level of the lowest outlet.

Great question, I never thought about it, and lucky for me, all of my boats are set up right...
