Was driving boat fast, had slowed down to idle for about five minutes then heard two beeps. Raised the engine cover and smoke came out. Engine was at 160 degrees (not hot). Oil pressure was at 40. Isolated it to the winterizer pump that was melting as it had fallen out of its holder and was touching the serpintine belt. The smoke did not cause the fire extinguisher to come on. Have not gotton boat past idle since but upon starting engine, but hear two beeps immediately (even with cold engine) and every three or so minutes the two beeps reoccur.
Talked to the marine shop we bought boat from and they said that melted pump might be the problem and just need to take boat in, put on computer and shut sensor off. However, he said he doesn't think that is the problem and just a coincidence that it occurred at the same time of some other problem.
What sensor is in alarm with two beeps when engine is hot or cold? What causes this sensor to go off? Do you all think the problem is just the melted pump caused the engine sensor to go off or should we examine other items? Is there a way to shut off the engine sensor without going to marine shop and hooking up to computer?
Items we have checked without the marine looking at it are:
1. Fluid level in stren drive oil is and was full
2. Disconnected CO'2 sensor - didn't stop the beeps
3. Oil filter was hot to touch and if left hand on it, think it would have burned me.
4. Exhaust manifolds (when looking at engine) left side was cooler than right side. Neither were so hot that you burned yourself.
Any guidance would be appreciated. Once fully resolved, I will update this forum with the root cause. Thanks!!!
