Water cooled motor ?

[MarkieMarkie]

Hello again!
Can someone help me with an answer and or information?
I have dusted off my Feilun FT011. It is running but not cooling. I have taken the boat apart and sucked water through the system to check for blocks.
Water is going through fine. But my question is; how is the boat sucking or pumping through water by itself?? There is no rotor inside anywhere.
Any help is useful.

Usually the water pick up is located behind the prop (or in the impeller assembly if a jet boat) to let it push water through the cooling loop.

Water “comes” in tube 1, goes through the metal to cool the motor, then tube 2, goes through the ESC and out via tube 3.
Yet there is no mechanism or rotor or anything anywhere to ‘pump’ or ‘suck’ the water through.

Look at your rudder. The tube is connected at the top of it. There will be holes in the rudder that catch water and push it through the system. Those holes can get clogged.

tube should go thru the transom to top of rudder bracket..

I’ll check thanx. So if I understand correctly, the water is ‘just’ being pushed up through the tube in front of the rudder and this happens just because of the speed of the boat through the water? No impeller anywhere, correct?

Correct

That answers my question, many thanks
