ESC cooling water flow

ESC cooling water flow...what is the best ...in the front and exit the rear...or ? does it make a difference ?
thanks

No, the ESC doesn't know front/back. You're just sending cool water through a warm heatsink.

I was just thinking that flow might be better front to rear......same direction of boat travel....I'll see what route the tubing fits he best.
thanks

Whatever results in the least amount of tubing in the boat.
