    3 trips out 2 ignition modules went bad

    An HEI distributor will not need a ballast resistor. It is designed to run on full voltage. The ignition module should also get full voltage. The ignition module should have some thermal paste on the bottom where it mounts to a metal plate to conduct heat away from it. If there isn't paste, it...

    The hull ID number will certainly give you the year, possibly info on the motor and drive if you can't find anything else

    What Bondo is saying in not as many words is don't forget to clean the negative terminal and grounding post on the engine block.

    Grease your gimbal bearing and see if it helps. Granted, it probably won't but it's at least really easy

    Assembling a 4.3 MerCruiser v6 - Parts check needed

    I don't know what your plans are for the boat, what condition it's in, or how much you plan to use it, but it's pretty hard to beat bang for the buck when you can get a good, relatively low mile engine from a truck for under $1000, put brass freeze plug in it, replace head bolts and gaskets if...

    Y pipe

    In the driveway, put the plug in and fill the bilge with water and see where it leaks out the back. Just be careful not to submerge anything you don't want wet.

    Assembling a 4.3 MerCruiser v6 - Parts check needed

    I would trust Melling's description of the cam over Summit's. Lot's of typos on Summit. High volume oil pump. Standard would be fine, but as the engine heats up or wears and pressure drops the high volume keeps the flow up. Personally, I would have checked the classifieds or junkyard for a...

    No oil pressure on 97 Monterey with 5.7

    I have had a broken oil pump intermediate shaft that resulted in no oil pressure. Oil pickup tube can fall off. Pull the dizzy and check intermediate shaft. And make sure dizzy shaft is intact

    Volvo Penta Drive Belt - Lots of dust and quickly wearing??

    Take a straight edge like a 2 foot bubble level or a carpenter's square across the pulleys edge. Make sure they are lined up with each other and not sitting crooked

    Volvo Penta Drive Belt - Lots of dust and quickly wearing??

    Make sure your pulleys are properly aligned. Put a straight edge across them and they should all line up. If not, they are improperly mounted or wrong pulleys or accessories are not correct or improperly mounted.

    1991 4.3 OMC Oil and Water

    @Lou C Are you suggesting removing the impeller and running without water? Wouldn't running with water flowing just milkshake again?

    1991 4.3 OMC Oil and Water

    Could be head gasket, intake manifold gasket, cracked block etc. First time out this year? Overheated? Improper winterization? If you think the motor can be saved you need to drain/flush all the milkshake out ASAP! I would drain what I can and fill the block all the way up with diesel fuel and...

    new GM 5.7 engine holes near oil filter

    The one above the oil filter is a oil pressure port generally used for an oil pressure safety switch if a marine application, often not used in automotive application. Other holes, if going to coolant passages can be coolant temp or drain plugs. If blind holes, may be for knock sensor. Just make...

    Hydraulic Lifter Volvo Penta 4.3 Vortec

    Those are the correct lifters. GM has used the same roller lifters in the 4.3 for its entire lifetime. Melling makes good engine parts

    Stalling at headway

    They should be fuel screws so in is lean and out is rich. I like to adjust while running and listen for rpm change. I go til fastest idle then 1/8 to 1/4 turn richer

    5.7L rebuild and upgrade to vortec heads

    I don't know if an 84 engine had tty head bolts but I would use new ones regardless. Also, the vortec manifold will require different bolts as well and likely a pipe plug or two to block off unneeded coolant outlets. And the appropriate gasket.

    Stalling at headway

    Engine should idle at 550-650 in gear. Sometimes tachs are not accurate so a digital tach or strobe can be used to verify actual rpms. I have successfully used a strobe tach app on my phone to verify idle rpm. You can also adjust idle mixture screws and see if it helps.

    sudden grinding noise then stallked.

    At the very least, it sounds like the flywheel bolts have backed out or sheared. But it could be a broken crankshaft. Motor has to come out and likely is toast.
