    Rebuilt my mercarb, now runs awfully

    Have you checked the fuel pressure? is the bowl over flowing , fuel dripping from boosters? Using the correct base gasket so there are no vacuum leaks

    Whole series of weird, seemingly unrelated events on Mercruiser 5.0L/Bravo 3

    IF it over heated then it went away most likely the raw water intakes were covered with debris or weeds. Common issue where I boat

    New engine installation

    Top hole is not used. Bottom hole goes into oil pressure gallery. On my mercruiser this has a T for the oil pressure switch and the oil pressure sender. I think it’s 1/8” npt, if not that it’s 1/4”npt. If you don’t have any senders or switches to go in just plug it with a pipe plug

    Obviously more pressure is better only water test under load will. luckily you have one of the easiest engines to drain , two drain plugs…

    4 cylinder pushrod cover replacement?

    As bondo states holding the gasket and cover vertical may be a pain. You could either put bolts in it to hold the gasket or glue the gasket to the cover with RTV or gasket adhesive, let that set up then put it on. You can always try it with the dizzy in place and take it out only if needed...

    Stalling, sudden low idle.

    I would verify your fuel pressure is ok and the regulator is still working ok. usually there is a gauge port on the regulator. Would also look down the bores to see if fuel is dripping off the boosters at idle. If present this would mean the fuel bowl is overflowing due to high fuel pressure or...

    Is this engine oil good?

    Most of the issues you see now flat tapped issues are new cams during break In. What people (resonably smart YouTube channels) is the cams and lifters are not machined correctly. Inconsistent or lacking taper to cam lobe and convex lifter bottom. Any oil quality or metalurgy issues are on top of...

    Best way to get to my boat?

    X2 on the floating dock. i installed a drive on mat from these guys https://gulfstreamdocks.com/ for my brothers 17 ft power cat. It just a bigger version of what you use for a jetski. where it might work for you is it’s made out of rectangular blocks that are held together with cam lock pins...

    easiest way to tell is crack your gas cap open if it is under vacuum then your vent is plugged, and if you open it it will remove the restriction getting fuel out of a tank under vacuum

    Ok Merc guys can you shed light on this....

    that may be I couldn't find anything in my PDF engine manual about it. Was thinking maybe Muc might see it and know

    Ok Merc guys can you shed light on this....

    yes its to heat under the carb for atomization as the vortec head has no exhaust crossover. I am not 100% sure if it takes exhaust gas or water- but thought it was exhaust not water. Definitely doesnt not circulate, assume it gets warm by being connected pathway. I would think he has a bad...

    Anybody familiar with these "Spindo" repair sleeves?

    Themselves don’t spin with the seal. I think what was mentioned above is the inner race of the inner bearing holds the sleeve on the spindle by compressing the o ring against the sleeve and pushing it against the vertical. this is just a guess on my part but since these are designed for...

    2012 3.0L TKS runs great with muffs, but slow on lake...

    So if the spark checks out ok you have verified the following are ok - compression ignition timing both at idle and total advance fuel supply /pressure I would think the only thing left would be go back to the carb rebuild, clean it again. Unless the hull is full of water or the bottom is...

    Engine wouldn't fire without throttle after overnight

    its a matter of ruling out low hanging fruit and multiple things could influence it as AD lays out. What is the gap on the plugs looks fairly wide but hard to tell from the screen?

    Engine wouldn't fire without throttle after overnight

    I would make sure the filter is clean, it would be the first thought when more air gets it running, but that seems to not be required every time? When you do have to add throttle is the exhaust black afterwards? if its been 8 years would be interested to see what the plugs and inside of dist...

    Engine wouldn't fire without throttle after overnight

    it at least bears looking into especially given the issues known with the crab style caps. in my experience if you have a good spark and any gas presence it will fire off easily.

    Engine wouldn't fire without throttle after overnight

    I would think needing to add throttle would be indicative of the IAC not working or screen being clogged. I wouldn't chase the rabbit hole of fuel pressure based on what you outline what kind of shape is the igntion system in ?

    Anybody familiar with these "Spindo" repair sleeves?

    you're right, this isn't a repair sleeve. it does go on differently - this is the bearing buddy version. Not sure if this better handles pressurized grease like with a bearing buddy ? Still not clear how the sleeve stays stationary on the spindle...
