"Hi,
I have an 96 Sundancer
"Hi,
I have an 96 Sundancer with a 5.7LX Mercruser engine (Alpha 1). I started getting an alarm last weekend and noticed that the temperature gauge was pegged at 200. I stopped the boat to take a look at the engine compartment for something obvious but found nothing. On my way back to my dock, I noticed that the temperature gauge was fluxuating from all the way left to 200 say every couple of mins. Note the alarm would go off ONLY when the temp was at 200. Starting the troubleshooting process, I changed the thermostat. No resolution. I checked the pressure from the impeller and it seems ok and steady.I back flushed the oil cooler. Still no resolution. Checked the intake on the sterndrive. All clean and no objects blocking. My mechanic thought it was the sender to the gauge (WRONG!). Now he thinks its exhaust gases going to the cooling system but has not proven it. Suggestions ???"
