    Not getting Spark on '86 3.0l Alpha 1

    For an '86 that 3.0 L is clean. Seeing only 12 volts on the opposite primary starter solenoid post I'd think the solenoid is bad. Pics show a most likely replaced starter assembly, best to remove and inspect/replace as necessary

    Slow trim response

    Guessing you're referring to the trim/tilt system? If so, then there is an issue with the system, most likely electrical. Unless you see extremely low oil/leaks or massive corrosion externally my guess is an electrical connection issue at least

    Mercruiser 4.3 Alpha One Stalling Into Neutral

    Top switch pictured is the shift interrupt. Lower one is the gear position switch Gear position switch is present so the ecm knows when the drive is in gear or in neutral. Reason is for the over rev in neutral alarm/fault. Kinda superfluous but with a diagnostic tool it allows the user to see...

    1997 Mercruiser 5.7 EFI blown head gasket

    And I'm quite sure specifically designed for the est ignition system. I'm thinking the proprietary end that connects to the coil has a diode in it

    Quadrajet Secondaries Problem

    I agree with nolamike. This forum isn't a tool to be used for vetting your mechanic's advice/skills. It's designed to help people repair their own boats I'll admit it's been amusing watching this thread and reading the vast amount of pragmatic advice you almost immediately disagree with or say...

    Quadrajet Secondaries Problem

    I clicked the link nolamike posted and read the broad strokes there. Seems luvboating just wants to argue. First guess from the older thread is the carb needs rebuild, can't do that. Second is secondaries aren't opening properly/at all, can't check that. Third is timing isn't advancing, won't...

Outboard charging system with some nla parts Many repair shops won't work on them these days Even people with a decent knowledge about them avoid...

    Mercruiser 4.3 will not start

    Quadrajet Secondaries Problem

    If this statement is true as pertaing to your local area then the marine service in question isn't a marine service I work on old/older boats. Boats/engines from 1955 through present day and I've removed and replaced many carburetor jets Either learn to rebuild a qauadrajet yourself or find a...
