    Engine wont shut off with key

    When running the voltage powering the coil goes thru a resistor which "should" drop the voltage down to around 9V. There is probably a weak connection in the key switch so voltage jumps around. It will start without full voltage (green wire) but will have a harder time doing so mostly when cold.

    3.0 power loss

    If it takes a while before it happens its not the valve When it happens, stop the motor. Go to the gas cap and get your ear close to the gas cap, then open the cap. If you hear air suck in then its the tank vent line, might be clogged

    TKS carb The antisiphon valve is connected to the top of tank and has a barbed fitting which the rubber fuel line connects that goes to the fuel filter/pump If you can start and it runs fine at first even at high speeds and then starts loosing power over some time. Can shut it down for a while...

    Mercruiser 4.3L Aplha 1, Gen 2 starting issues

    How was this checked? My guess is the motor took on water from stopping abruptly. Need to take all plugs out and crank the motor over a few times. If it doesn't start after that, go thru the TBV troubleshooting guide

    2009 Mercruiser 3.0L TKS stalling

    Check your fuel delivery system. Fuel filter contents in clear container. Disconnect power to coil and remove fuel line. Crank motor and see how fuel comes out, a little or a lot.

    Engine wont shut off with key

    That's what I'm saying, the power is coming from the solenoid. The slight spark is normal because it powers the motor back up, same as turning key ON Figure you have a multi meter. Check for a connection between I and the right side post on the old solenoid. If there is a connection and the...

    Engine wont shut off with key

    I've got nothing then, just know how it should work You removed the Tan wire (yours is Green) and have 12V on the post, not the wire. That wire feeds power direct to the coil and back to the key Maybe the new solenoid is bad, or its wired internally different

    Engine wont shut off with key

    The Ah Ha moment. New solenoid but terminals are different. Swap the Bat and Starter cables The Ignition and Starter are and "should be" connected together. This way when the solenoid energizes the starter it also supplies full volts to the coil for starting. When key is released power is...

    Another idea, get everything good and clean the JB weld it on. Again it will be a real pain if it ever did leak or had another problem
