    4.3lx intake manifold question

    Do you have a zoomed out shot so we can see it vs. the original?

    Ran amazing then shake no thrust

    And not sure how adept with a carb you are, but you're looking at the throttle blades and not the choke, right?

    Ran amazing then shake no thrust

    That's where I was going. Enough to get back to dock, hopefully enough to not overheat the engine severely, but continuing to drive and then no start... Op, did the revs increase but the boat didn't go faster, it did the revs stay low when you hit the throttle?

    Need advice from experienced people.

    Yes, and it will also put you on a path to replacing your engine. Your blowby compression test also means nothing... Nice a avatar!

    Except next time you remove the sender, "plop" into the tank?

    1978 5.7l pre-alpha with alpha gen 1 drive over heating

    Also make sure you check the water pocket in the upper, if melted it lets exhaust gas into your cooling stream

    Lost trim gauge and water temp indications

    Yes. Trim sender wires are somewhere coming in through the transom. Yes, doing the tests will help you figure out whether it's the wiring, the senders, or the gauges.

    Lost trim gauge and water temp indications

    Engine bay One lead of the gauge goes to engine ground, the other goes to the (tan, or brn/wht) sender wire

    Lost trim gauge and water temp indications

    I thought I did... I'll try again Step 2 just use a voltmeter connected to ground on 1 side and sender wire disconnected on the other side (tan is water, brn/wht trim). You should get 12v, gauge reads 0/all the way to the left. Next ground the sender wire, and the gauges should peg to the right.

    1. Locate the sensor. 2. Verify that you have 12v in Key on: 3. Disconnect the sender wire. Gauge should go to 0. 4. Ground sender terminal, gauge should peg

    89 centry palimino with a 3.7 mercruser charging issue.

    No problems when I did mine, took about an hour. The included alt seized after a year though

    Crank, no spark. Need advice.

    If you did the test correctly and there's no spark, next step is replace the coil (rarely bad), and if that doesn't work, replace ignition module (very rarely bad). Ignition sensor is the most common fail point, so make sure you're testing correctly. I also saw a post advising you to reconnect...

    Boat won’t start, have spark and fuel

    "tad dim"... Should be blue. Use a gap you're tester if there's doubt. Did you mess with the distributor or cap? Did you ensure that the #1 plug wire is aligned with the rotor when the engine is at TDC? Also pour some gas down the carb to rule out fuel problem if you've exhausted other...

    Air Fuel Ratio Carb Tuning

    I'm dying to do this. Those numbers seem rich. Might try to see what the TBI models run at. Esp with the Holley sniper systems you might be able to find that out relatively easily

    89 centry palimino with a 3.7 mercruser charging issue.

    I still have yet to see anyone successfully replace the regulator with something else... Would love to see it.

    Starting Issue After Unrelated Mech Repairs

    @tpenfield , time to change it?

    Drive stuck in forward position

    Just to be clear: if you turn the shifter all the way clockwise, and hold it there while turning the prop CCW, the prop should lock. If it doesn't you have bigger problems, and might need to be looking for a new drive.

    Bravos don't have that problem, which is what's likely on a boat that size
