water comes from the pump,, remove the hose and back flush it to clean it out,, if it isn't clogged then you either have sand in the water jackets or the exhaust water box is full of sand,, once you get a kaw hot you need to pull the head and replace the head gasket surface the head and re torque the head,, with the head removed you can see if sand has built up in the water jackets, usually it is the hose next to the pump that gets clogged .

if it's that hot you may have sand in the cooling system or the water box
