I have a 2001 5.0L 2 Barrel MerCruiser that is stalling out. I was just de-winterizing the boat and I am having this issue. This is not the first time the stall has happened. Two years ago the same thing happened and I was able to final get the boat going and the boat was fine the rest of the year. The symptoms are as follows: The boat will start and run fine for a short period of time. The time is about 2 minutes at idle and about 45 seconds at full open. I have pulled the carb and cleaned it. I used a new gaskets, but the problem persists. I checked the fuel pump and that is pushing fuel. I had replaced the fuel filter. I replaced the oil sensor due to the gauge was reading high, but the gauge is still reading high. I think it might be the gauge. It is reading 80 psi. The serial number is 0M080027. Any help or ideas would be appreciated.
