Cooling water inlet / outlet 4mm

Cooling water inlet and outlet small Inner Ø 4.2 mm, outer Ø 7.0 mm, with fixing screw

The cooling water inlet and outlet made of black plastic pushes the water into the cooling circuit and also sucks it off at the same time. This does not create overpressure in the cooling system. Grass, leaves or feathers can not stick to it because it has only minimal resistance in the water. Drill 3 holes and seal with superglue. Suitable for silicone hose 4-5mm inside.

The system works even at the lowest speed in prototypical ships.

Installation near the shaft

For racing boats with combustion engines, it can also be used to extract spray water in the boat
