Problem Fixed, Guess what it was?
 

First, thanks everyone for your help and ideas. I hope I can help someone else out down the road.

Problem= Buzzer beeping.

I went through everything. Electrical- checked and replaced etc. Water Intake-hoses, seawater pump, thermostat etc. Then went and bought a water pressure guage, no pressure. So I removed all, hoses, I mean all, to check for obstruction. All was clear, until I got to the hose for the circulating pump.

What fell out?, you ask.

Answer= a one-inch piece of fuel line hose, one-half of a black walnut, and a golf ball. Removed said items and went for a test run, all is well.
This is a brand new motor installed by dealer. Dealer admitted they recently fired a mechanic who probably sabataged my motor. Apparently I was the lucky guy. Got the impression there may other lucky winners.

Glad you found it before the motor ov erheated and blew :(

A friend of mine that was a mechanic at a Pontiac dealership had a car come in for warranty work. The owner stated there was a rattle under his feet and this was the third time the car was in for the same problem. He looked and looked and drove the car but could not find anything. He was just about to give up when he noticed something shiney inside the frame rail. Upon further inspection it was a coke bottle that was inside the frame rail. There was no way to get the bottle in there, or out of there, with the body on the frame. So it had been there since it was built. He found a way to break the bottle and suck out all the pieces. Along with the glass came a note that was in the bottle that read, "Congratulations, you found it!"
