    Perfectly for 15 minutes then, surging, knocking, and jumping tac

    Different opinions OP said it was correctly and no issues, and later with issues and same flashing Timing light picks up off how well the the pickup works. Was the issue the differences in resistance of the wires, the wire or there was actual missing? Don't know, it would take 4 spark gap...

    2008 4.3 ltr. TKS diesels when turning off

    Its dieseling because its idling to high, fix that and the issue goes away Start the motor and let it warm up. Once warm at idle, disconnect the throttle cable from the carb. Push carb closed so its at low correct idle Adjust the cable at the barrel nut so it just slides back into place...

    Starting in hot afternoon

    Watching the gauge, If you turn the key and pressure builds to 50 but falls off quickly, I would think regulator first. If it bleed off slowly I would think injector If it takes several key cycles to build pressure then I'm leaning toward failing pump, antisiphon valve, tank vent line...

    Mercruiser 5.0 MPI #3 cylinder ignition miss

Sold my 95 model this year and mans were changed. Replaced the ones on my 94 (repower needed better flow style) some years back...

    Mercruiser 5.0 MPI #3 cylinder ignition miss

    The bulletin posted was just to make the tool from, not for your motor. It dealt with emission motors which yours is not. The comment I was making is (not knowing what your serial number is) I don't know your complete configuration so just spitballing right now. The breaker comment was the...

    Mercruiser 5.0 MPI #3 cylinder ignition miss

    I would check the clocking on the Dizzy. Best method is to make the $10 tool in the bulletin Can also be caused by yellow flag circuit breaker (50 amp) but you should not have one of those Edit: don't know your serial number

    Newbie needs some help please!

    Might be an illusion but think the water pump pulley is set to far in, needs to come out some. Use a straight edge and place on the circulating pump above the crank or the crank pulley to see

    Fuel system fail on new boat

    If you have 2 motors running off one fuel line Tee'd to the 2 motors, that doesn't work. It can work if you put valves on the fuel line to turn the motor not be used OFF

    Mercruiser ECM replacement?

    With those codes, it says the tps voltage is to high, so there may be an issue with it or supply voltage is getting to signal wire The other deals with the dizzy module

    Mercruiser ECM replacement?

    If you find the screen is clogged just toss it. No need for a screen that has larger holes then the filter If you have a compressor and hand adjustable Reg. Use rubber tip and connect to base of cool fuel Reg. Adjust air pressure up slowly and it should open at 30 psi
