    Mercruiser 120 poor starting

    Gapping alone may get you home , but it isn't accurate it in the +/-40% range Dwell needs to be correct to get coil saturation so that when the points open, the magnetic field is as strong as possible when it collapses and energizes the secondary windings providing the coil output The meter...

    Making a Bigger Deal than it is? - Trim Flush

    I would pull the pump, the plastic reservoirs are known to crack after 15 years That will allow you to inspect and clean the reservoir The only way water enters thru the cap is if the pump was submerged Most likely one of the cylinders has a seal leak. The hydraulic seals last 15-20 years

    Left stranded on ICW - '07 5.0 GXI Safety Lanyard circuit?

    the safety lanyard is usually just a break in the ignition wire. so if its not working, nothing back to the engine will work. follow the purple wire from the key switch, it then goes thru the safety lanyard, then to the motor.

    Mercruiser 4.3L - Stumbles at 3000RPM

    I would have pulled the carb apart by now and been out a few bucks for gaskets. regarding fuel pressure, its either there or not. most intermittent issues are not fuel supply related as the fuel bowl in the carb has enough fuel in it to run for a few minutes. the fact the motor runs at...

    Mercruiser 4.3L - Stumbles at 3000RPM

    It's almost never the coil. Coils work or they don't. They are not ever problematic at a specific RPM in the middle of the range

    Mercruiser 4.3L - Stumbles at 3000RPM

    The filter at the carb will pass small rocks. It's about a 100 micron filter. The spin on one is 11 micron. Look at the water separating filter....looking for water

    Mercruiser 4.3L - Stumbles at 3000RPM

    how old is the fuel? when was the fuel/water separator filter last serviced? have you checked the content of the fuel filter for water? when was the carb last cleaned. it sounds like either water in the fuel, bad fuel, or dirty carb.

    Starter Not Engaging

    the seloc manual isnt worth being used for anything more than a knee pad. look at the pilot relay for the starter. follow the yellow wire with red stripe. being EFI, the relay should be next to the fuel pump relay.
