btw the ski has 451 hours and I cannot even locate the darn sensor to see if I could just fix a short or see if something had come loose.

You can run the engine with a bad EGT sensor but it won't run optimally. The ECU basically uses the EGT sensor in place of an O2 sensor. It is looking for an ideal temp at a given throttle position and will adjust ignition timing and fueling to meet it. If the sensor isn't working it will fall into a failsafe timing table where it should be able to run safely till repairs are made.
