    Troubleshooting ignition coil 5.0 Mercruiser

    Funny story about fuel pressure, after I installed the new electric fuel pump, I got one of those rental fuel pressure test kits but it was defective and sprayed fuel at me out the pressure relief. That’s when I took it to the shop where it sat for 3-1/2 weeks. I called another shop that told me...

    Troubleshooting ignition coil 5.0 Mercruiser

    My boat starts and idles great but when I get up to 1200-1400rpm it it Boggs down. It’s a 2006 Mercruiser 5.0 MCM. I’ve sprayed a mist of fuel into carburetor intake and nothing happens so I’m thinking it’s in the ignition system. I’ve put new plugs/wires cap and rotor. Looking at the coil, I...

    Carb float level adjustment help

    I’m thinking the muffs weren’t on tight enough because I was loosing water around the sides. Not under a load. I had removed the thermostat so I’m waiting on the new one to do much more testing.

    Carb float level adjustment help

    Maybe it was air in the new fuel line I’ll run it more later and work the kinks out. May end up raising the float level it’s at 14mm?

    Carb float level adjustment help

    Carb float level adjustment help

    I have a 5.0 and it starts and idles perfect but when I throttle up it bggs down. I recently put new gaskets on the carb. Is it possible I knocked my float level off causing a fuel starvation issue?

    High oil pressure smell of gas in oil

    Wouldn’t surprise me I’ve ran into some sketchy stuff with this boat. It just seems like as soon as one problem is corrected another presents itself. I did do a voltage drop test and found a .96v drop on the positive side of the circuit. I had just went through all the negative terminations and...
