    Mercruiser 4.3 Engine - empty carb bowl

    I'd the carb bowl is empty, you either have leaking welsh plugs or the carb sat for 3 weeks or more

    OMC COBRA 5.8 EFI and ESA

    You have a leaky seal, it allowed water into the gearcase, and expelled oil. The AI BS is BS. All sealed gearcase will "burp" if the gearcase is opened when its warmer than when it was filled, and "gasp" if cooler. That is just the fundamental law of PV=nrT
