Westerbeke 7.0 BCG genset woes
I have a 7.0BCG Westerbeke.
Mine is 6 yrs old, with 650 hours (I personally put 200 on it since last November, when I bought the boat.) Last week, it ran down in rpms a couple of times, and then died. All efforts to restart have failed. I was low on fuel in the supply tank, and figured that was the problem. I have checked all safety systems, lifted the overspeed module connection, and as long as I hold both the start switch AND the oil pressure override switch down, it sounds like it has started and is running. I am perhaps fooling myself because I'm sure the starter is engaged while I'm holding down the start switch. If I release either, the engine dies, like you hit the stop switch. I have measured a good 12v on the fuel cutoff solenoid, even when the switches are released. I have cracked the solenoid from the carb housing, and have fuel running out, so I "don't" think I have a fuel pump problem. I am not developing A/C voltage, though. IT's like 10 volts on the panel meter, or something trivial during the start. Would the lack of the battery charger output from the A/C side be causing this symptom? Any other ideas? |

BCG = GAS
However, like I said, it was running off of a low tank. I'm going to spin the fuel/water sep and see if it is full, or dry. Did you bleed the fuel lines, AND the injector lines off all the air that got pumped into them when you ran out of fuel? Air compresses very well in the injector pump but will NOT open the injector valves. Sounds like you still have air in the injector lines. Bleed all the lines untill you have good fuel going into the top of each injector, and try starting it again....... Bruce in alaska |

Just a guess....But is it possible that there was a little bit of water in
the bottom of the fuel tank which was sucked into the carburetor? This would explain the drops in RPM as the water filled the bottom of the carb float bowl until the water level raised enough to stop the genset from running. You would still see liquids in the fuel lines like you saw. See if there is an easy way to drain the carbureator bowl and catch the contents in a clear jar. Water will sink to the bottom. The low voltage you are reading may be normal until the unit is up to speed... Good Luck! Last week, it ran down in rpms a couple of times, and then died. All efforts to restart have failed.
