I was commissioning my boat and engine. Everything went well until I tried to start the engine to burn off the fogging oil.
Before turning the ignition switch I replaced the t-stat and and t-stat gasket. Everything checked out.
I reviewed the Indicator Light/Buzzer Operation grid. At the start the oil pressure light is green and stays on, the Overheat Sensor light is red and on for 2 seconds, the Alternator light is red and stays on, the MIL light is red and stays on for 2 seconds. The warning buzzer sounds twice.
There is no spark as the the engine doesn't turn over.
I checked the overheat sensor. The connection was good and clean. The sensor was covered with a soft silvery light paste. There wasn't a lot, and it wasn't clogging the water flow.
I tried starting the engine a couple of times. The same result each time. After the warning buzzer I could hear what sounded like a pump pushing water. I couldn't get close enough to engine to hear where was coming from.
I removed the Flush Valve, and everything checked out.
I checked each spark plug, and everything was fine.
Do I need to replace the overheat sensor? The ECM?
I neglected to check the fuses. With all four lights working, and the buzzer sounding I don't think its a fuse.
The engine manufacture date is 1998, and has never given me any serious problems.
Thoughts?
Thanks.
