I have the following problem with my 1988, 150-hp, Evinrude. My motor was overheating. I went along and changed the entire water pump housin, thermostats, puppet valves, all deflectors and cleaned all the water channels and the motor is still overheating. I also noticed that there is cold water dripping down the mid section of the motor and comes out by the side of the lower unit. I know that this is not water that is coming out of the motor after circulating in it, because the water is cold when you touch it, which leads me to belief that there must be a water leak some where between the water pump and the powerhead which is preventing the right amount of water to enter into the powerhead in order to cool it properly. Does anyone know of all the possible reasons as to where this leak could be coming from, and if so, what do I need to do in order to fix it. Your help would be greatly appreciated. Thanks!
