    2007 Mercruiser 4.3 w/ cracked block

    You won't be using the fuel injection, you'll be using your fuel system and intake. Dunno what more balanced cam shaft would be. Also might not need new head gaskets or core plugs. My '02 blazer engine had brass plugs and composite head gaskets. Of course, you'd have to pull at least one head to...

    My boat is being a boat . . .

    Yeah noticed that. I've heard nothing but crazy train in my house for the last month as my kid is trying to learn it on guitar

    95 4.3lx alpha one mercruiser cooling system question

    Can't find the specs ATM, it's in a manual somewhere, but it's around 15 gpm. But I misread your post; drawing it from a bucket isn't a valid way to test it

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    So your misfires/problems changed cylinders? I'd still try swapping out that #5 injector with something on the other bank. How do you know it's #5? Also not just lack of fuel causes high FT--vacuum/air leak is pretty common as well. But that would affect the whole bank, and not just 1 cylinder.

    Sorry if I missed something, but I’m looking for a manual for my 1992 4.3

    You need manual #7. You should have TB IV ignition. Timing is 8' btdc, it doesn't get set into base mode to time it.

    4.3 mercrusier wires go to??

    Yeah, couldn't remember limit switch colors off hand. Couldn't figure why they'd be twisted otherwise though unless they're grounds. Feel good about that other wire being from the TKS mod though.

    4.3 mercrusier wires go to??

    If that wire is red/purple then it goes to tks module. I was thinking the twisted wires were from the trim limit switch and someone jumped them.

    Oil filter socket

    I have many wrenches and sockets, but the correct one always hides when needed. But I always can find a big ass adjustable wrench, and if needed a big screwdriver :)

    5.7 alpha knock please listen

    Nobody but me thinks that sounds like a rod knock?

    4.3 mercrusier wires go to??

    Looks like a TKS model... I'll go with alternator output for orange (if original wiring) and maybe trim limit switch? Need to see where they go... Yeah, don't do that 😄

    350 Magnum - exhaust riser damaged brass plug

    Just turn the engine over. If waters in there it will spurt out and drain the cylinders.

    Maintenance - New owner of 89 Mercruiser 4.3L Alpha One

    Those prices are shockingly high. Get any standard grease gun and marine grease for most things. Look around the forums for a lively oil debate, but most here don't use quicksilver oil. I grudgingly use either QS or sierra high performance in the drive. The lube pumps are pretty much the same...

    Mercruiser lower reinstall, small problem

    Yes, that washer is an escape artist. I've used any ol washer multiple times. Not a precision piece, just needs to lift up that shift shaft enough to engage the shoe. (I also may have used a zip tie for a time under the lip on the shaft as a temporary fix to raise it up)

    Is my Mercruiser fuel injected or carb?

    However a tbi doesn't have fuel rails or a return line either
