Here you go ! Pull the hose # 7 where it connects to steering cooler and start motor.Sometimes there exists a air lock and this hose will take care of that .Water will pour out fast when you point this hose overboard.Stop motor and reconnect.Then if you want a cool running boat look at the first parts diagram, 7 point and change your system to that configuration.Money well spent and not hard to do.Single point or 3 point whatever you want to call them are total disasters,this system does not cool well in my opinion.
