    3.0 Mercruiser Choking

    By not being sure of the float bracket adjustment I take that to mean the float level is not set correctly? Yes if float level is off this could cause what you are observing. Also would look did you install any check balls in the accelerator pump circuit correctly? If you disconnect the...

    Worth flame arrestor upgrade for Mercruiser engines?

    They can run rich if it is severely clogged as it can act as a choke, but nothing a little gas , scrubbing , and blowing out with compressed air cant fix Isn't that all gonna hold together when you put it on the carb and screw it down?

    Rebuild of a 3.7 180hp mercruiser have questions

    Buy new lifters you can reuse the pushrods and rockers of they look ok. You will likely need a speedi sleeve for where seal wears the camshaft snout If the head or block needs decking you will have to change the pushrod length to correct the valvetrain geometry. How far are you into this...

    Making sure I purchased the correct coil for a 1996 5.7L

    if your timing spec is 8 it should be at 8 in base mode not 0. It is usually on the flam arrestor and also in the shop manual. When you come out of base mode you will see the ignition module advance it some as the TBV is an active system where it is changing the advance based on engine conditions

    Cracked 5.7 engine

    Real repair is to replace the engine. But If you are lucky enough that it doesn't get into your oil after a couple of good hard uses , JB weld the crack and it is what is ... There is something called lock and stitch to repair cracks but would think it wouldn't be worth it in this...

    1997 Merc 4.3 V6 LXGen+

    Would second this. Marine engines under load have a much higher detonation potential than automotive applications, detonation that can eat your engine for lunch in a short time. Would suggest getting a timing light and setting it properly and verifying total advance

    2005 Mercruiser 5.0 thunderbolt V ignition has no sparks

    Yes with key in run position and kill switch on you should have 12v to purple wire on positive side of the coil. Tripping the kill switch should interrupt 12v to positive side of coil. If it doesn't kill switch is bad or someone jumpered around it because it was bad...

    2005 Mercruiser 5.0 thunderbolt V ignition has no sparks

    Yes you need the sensor based off your tests. The kill switch interrupts the 12v supply to positive side of coil (purple wire). That was in the beginning of the troubleshooting guide. You may want to look at the distributor I think to remove the sensor the rotor and trigger wheel needs to come...
