Its only a tiny water Pump but Its got an enormous flow

Its only a tiny water Pump but Its got an enormous flow. Cooling pump for Yellow Boat 3 COuld be a candidate for a temperature sensor and current sensor to control the pump with a trusty Arduino nano. The pump motor draws 100mA on load.
Testing YB3 in the bath its totally mental on 6 cells 569 Watts flat out nearly emptied the bath should be amusing on the lake, that said at this power level it needs the motor cooling
Its made from an old servo motor motor a small brass impeller made from sheet brass and brass tube, soldered onto the pinion. The pinion is then secured with Locktight to the motor shaft. The shaft seal is from a non drip honey bottle glued on the end of the motor.The pump body is a part out of the top of a pump bottle soap dispenser, all held together with epoxy and Fiberglass.
The little pump shifts plenty of flow though the big pipes motor first them ESC a power test will be run to evaluate the performance of the cooling system, it seems to prime its self Ok. There is a rectangular scoop on the outside of the hull to help the flow when the boat is traveling. Having a pump means the temp won't overshoot after a fast run and stop like it would if it were only a scoop or tap from the jet unit nozzel.
Another tiny pump probably much more expensive than mine
