    lack of power on 4.3 thunderbolt 5

    Things that are easy to mess up: 1. Firing order. Check/double check. 2. #1 wire is in fact pointing at the #1 cylinder on the compression stroke/TDC 3. Plug wire not seated correctly on the plugs. Kind of tough to access on these engines. Do you still have the old parts? Certainly not unheard...

    Water leak

    Don't do that. First thing to check is the condition of the bellows. If it's been sitting since '04 they're at least 20+ years old and likely a good bit older. Has it been stored outside or inside? Does it happen while sitting in the water, engine off? How about out of the water on muffs?

    Spark Plugs for a 1985 Mercruiser 3.0 Alpha One 140hp

    The delcos are corrosion resistant; afaik they're the only ones. After having a close call with ngks a while back I'll stick with the delcos whenever possible

    Mercruiser 3.0 overheated, Is my motor shot?

    The grommets and water pocket cover are still getting water if the impeller is working though.

    Mercruiser 3.0 overheated, Is my motor shot?

    Again, he shouldn't have any issues with the lower unit

    Mercruiser 3.0 overheated, Is my motor shot?

    His overheat occurred after the transom

    Mercruiser 3.0 overheated, Is my motor shot?

    I'd do a compression test, make sure it turns over easily, let er rip and see what happens. Can't imagine removing the head just because. Your rubber boots and flappers are toast, and you will need to find out where the pieces ended up. And even without the compression test you'll know pretty...

    Insurance

    My primary liability is a rider with the homeowners, and my umbrella does cover after that. No umbrella provides stand alone coverage afaik.

    This. Not to mention your deductible. Not sure if a marine claim would count against your other insurance lines also...

    TRANSOM ISSUES!!!!

    Seems like a bit of a shotgun approach. Certainly worth drilling down further in the transom to check out its condition though.

    I'm doing my Bellows. Mercruiser A1G1. Are the Amazon Bellows Kits any good?

    My litmus is how much pain does it take to get in there and redo the job. I've had good luck with Sierra, but for a bellows job I would certainly not go cheap. Also, if there's a failure of the part is it going to leave me stranded or just inconvenienced? How easy is it to cheap out on the part...

    Help me identify whether I have a 1" or 1 and 1/8" shaft

    And if my high school geometry is correct, closer still to 3.1416 😀

    Ujoints clunking?

    At least on my alpha no problems greasing with the zerk in that location.

    Sea Pro 195 F/S fuel tank size

    Empty it and refill. That will get you very close, although not close enough for me to trust with a premix. Now you know how much you added, so add the appropriate amount of oil. Going forward, just add your 16 oz to every 6 gallons or whatever.

    Wiring positive cable from Amps to battery or common on Switch?

    Most (all?) amps that I've seen are turned on by the head unit anyway, so while there's battery power to the amp at all times, it isn't "on". I have my head unit on a switch, so unless the switch is on the head unit isn't getting power. If there were an acc position on my ignition switch I'd...

    I Got Me a Mercury !!!

    You got me interested. Seem s like it's still closer to a CDI type system than a points system electrically. This is the most in-depth explanation that I found, though the writing is a bit dramatic: https://wrcoutboards.org/wp-content/uploads/2021/02/The-Phase-Maker-CDI.pdf Also, you probably...

    1986 Four Winns Horizon 190, Carb Linkage?

    @Lou C can help with the carb, although that doesn't sound like the issue anymore. At speed, try closing the choke a bit manually or covering the air intake. You should lose speed. What do the plugs look like? "Compression is good"--numbers? Timing--have you checked it, and make sure it's...

    Mercruiser 3.0L LX - EST Ignition - how to check for proper spark?

    This will tell you if there's the impulse for the spark, but not the quality. Good first step but not definitive. That said, if this is all 4 cylinders then probably fuel. 2 cylinders OP could be dropping cylinders from ignition/compression/fuel. Best way to check is with a dedicated spark...
