Good evening.
I have a 2003 4.3 mercruiser, carbureted engine. Three times now, my motor has suddenly died while running. It will crank over, but not fire. It seems like its out of fuel. The only way to get it to start is to jumper the fuel pump with 12 volts. Once I refill the float bowl, the boat starts, and will continue to run, no problem. The first 2 times, I was slowly cruising and thought maybe my oil pressure was too low due to prolonged running at low rpm. This evening it did it while pulling a tube, and running at 3000 rpm or slightly higher. My oil pressure was 40 psi pretty consistently at that rpm. Any thoughts?
