Today I've started to play with a little water pump found on ebay.
The first impression is positive but I need to test it some more.
The main problem is that this pump is not self aspirating and so the circuit must be primed but is sufficient to run the boat for a while and as soon as the air is replaced with water it keep on going.
The first advantage is to cool the ESC and the Motor before to start, just let the pump run for a while and the temp inside the cooling system will be the same as the water temp.
