I'm new to my 73 65hp Evinrude. I do not see any water spewing out any small holes indicating that the water pump is working. Does this model have any tell-tale holes?<br /><br />Also, under the thermostat housing I have the thermostat and 2 springs pressing on 2 plastic valves. What are these 2 plastic valves for. The tension on the springs seem so great that I couldn't image water pressure opening the valves. what are they for?<br /><br />Thanks
