After changing the fuel filter, I was having a problem triing to start my 3GM30F. I tried starting it numerous time. It finally started, but the Water Temp light & Buzzer stayed on. I went below to see if the switch was connected, then I notice a small amount of water draining out of the air intake. I realized I should have close the raw water intake but what do I now? How can I make sure I did not put water into the cylinder(s)? How you I test the water temp switch?

Thanks
