    Engine starts, idles for 10 seconds then dies

    Yeah, not sure why the effort wouldn't go towards fixing the flooding carb first

    F-150 Transmission Issues (I think? . . . No, I thought )

    Man, all this ford bashing. Jealous of that fix. My mini is/(was?) throwing insufficient boost pressure codes. Wastegate and diverter valve (as well as the turbo itself) are common culprits. To inspect the wastegate, I need to remove the exhaust and cat (that should be fun). If it needs...

    Popping through carb at 4000 rpm

    they make a spacer that sits on top of the exhaust manifold. dunno what the rest of the question was

    Popping through carb at 4000 rpm

    you need more fuel with higher rpms, so not really. secondaries opening? fwiw, I absolutely love my a/f gauge that I installed. takes all of the guess work out of the equation as to whether/when you run rich/lean

    Throttle spring on 1981 Mercruiser 120. Courting disaster

    What carb do you have? How is the throttle opening with the cable holding it closed?

    Mercruiser 140 (1984) - What started as key no longer turning off boat has evolved into boat not starting at all

    So the fault is after the ignition switch. It's a totally separate circuit after the ignition switch. No. The choke supplies the coil. If you don't have switched power at the choke, you probably don't have it anywhere in the engine compartment. You still haven't tested that though. The...

    Mercruiser 140 (1984) - What started as key no longer turning off boat has evolved into boat not starting at all

    That's your issue. You should have 12v key on. Choke should have 12v also. See post #14. You didn't respond if gauges are also dead. There's a break in the circuit somewhere between the purple/red wire to the helm (do the accessories--blower, bow lights,etc work?) or in the purple wire from the...

    Mercruiser 140 (1984) - What started as key no longer turning off boat has evolved into boat not starting at all

    You're measuring either volts or continuity, which is it? You can replace it all you want, coil too. Neither are your problem.

    Mercruiser 140 (1984) - What started as key no longer turning off boat has evolved into boat not starting at all

    Yup. The conversions need 12v, which is what the red wire should be doing. The black is the trigger wire from the system, so grounds out the coil (-) and should be attached there like a points system.

    Mercruiser 140 (1984) - What started as key no longer turning off boat has evolved into boat not starting at all

    Kind of...still hard to tell what's going on. Your P/Grey wire is the P/Y I was talking about. Pertronix wire looks new, and is what's powering the ignition module. Yellow wire...not sure, but guessing that should be hot from the choke with the ignition on (and that terminal at the choke)...

    Mercruiser 140 (1984) - What started as key no longer turning off boat has evolved into boat not starting at all

    Ok. so not sure how your pertronix is wired. Originally though, when your key is in "start", a purple/yellow wire is energized from the starter, supplying 12v to the coil. When you let off the switch to "run", the ignition circuit takes over. With the points system, the coil is powered by a...

    Mercruiser 140 (1984) - What started as key no longer turning off boat has evolved into boat not starting at all

    Key off, are you getting 12v at the coil pos when engine off? Presumably you are with the engine on

    Since we don't know what you're working on, I'm going to say you have a bad TKS diode.

    . . . and I Thought Hi-tech Boat Engines Were Bad . . .

    When I got my mini, I went through this. Low battery throws a ton of codes. Not only is the battery a PITA to replace, but you need to recode if you swap a different Ah battery, AGM for lead acid, etc. My last car ('02 330Ci) I bought with 135k miles and sold with 235k. Was mostly pretty...

    Twin Merc V8 and different fuel usage

    How hard to run each motor on a separate Jerry can? This would give you the most accurate info. How far off are they as a %?
