    1990 vs 1992 4.3 block swap

    Try the round Merc/Quicksilver muffs with the metal rod clamp; these are made of softer rubber than the generic muffs and conform to the shape of the lower unit better.

    Gas leaking from tank inlet

    If it vents thru the cap there may be something wrong with the venting function, I’d try replacing the cap. I have the old style separate vent & never had that problem…

    Ruined Engine

    it doesn't exactly make sense does it? I'm wondering if....someone....dropped a washer....or nut....or bolt...down the center of the exhaust passage in the manifold....while installing & didn't realize it....hard to imagine....but I guess anything's possible.... However, when my engine...

    Ruined Engine

    That’s common on small block Chevrolets that are overheated Happened to mine but I didn’t have the noise or white smoke no symptoms at all. I had water in the cyls but that was from blown head gaskets

    Mercruiser 4.3L lift points

    Next you may have to do this and spray all around the cylinders to see if you can get it to move..... Mine never locked up even though it was salt water because I suspected that there was water in the cyls from when it started acting up (difficulty starting, misfiring etc). So I started draining...

    2002 5.0 GXI Cooling System Service

    Manifolds & exhaust elbows….are the cooling passages getting clogged? Water had to get IN, pick up heat from the engine & exhaust but it must also get OUT….that’s where the exhaust comes in….

    Try a rust penetrant like: Kano Kroil Free All Freeze Off Or a home brew of 50/50 mix of auto trans fluid & acetone

    Yep you want sone kind of lubrication in there with perhaps some rust penetrating oil to dissolve rust on the cyl walls. That’s what must happen to free up the engine.

    It doesn’t always show on the dipstick right away; take off the oil cap on the valve cover & look inside

    Yeah could be locked by rust in the cyls

    Ruined Engine

    Ahh there must be MORE to this story?! Is that a cloud of white smoke behind the boat? Just how hot did the engines get?! That sounds really bad, you might just need a new engine.

    Mercruiser 4.3L lift points

    You seem to have at least 2 problems the water in the cyls & perhaps a bad starter. Now you have to figure out how the water is getting in (bad exhaust system, blown head gasket/cracked head) and repair that. Then change the oil repeatedly till you get the water out of the oil. Spray fogging...

    Mercruiser 4.3L lift points

    You can tell if there is water in the cylinders by removing the spark plugs & cranking the engine over (try to start it). If water comes out of the spark plug holes that’s bad; it could be a leaky exhaust system (remember the exhaust system on inboard boats is water cooled) or an internal engine...

    Different risers and elbows

    Or you will have persistent leaks at the rubber exhaust hose connections.

    Mercruiser 4.3L lift points

    You have the old big Delco style starter or the newer smaller PMGR style? If the Delco you probably need a new solenoid. If the newer smaller style do not hit these with a hammer it will break the magnets inside! However first check every connection in the starter circuit & battery cable...

    Mercruiser 4.3L lift points

    Actually you should not have steam like that esp with the engine temp of only 120*F. You problem is that the rubber hoses feeding the exhaust elbows are kinked (too short) and the elbows are likely not getting enough raw water flow hence the exhaust steam. My OMC Cobra has the same engine and...

    Mercruiser 4.3L lift points

    A couple things One if the engine doesn’t crank over I would first remove the spark plugs to make sure there is no water in the cylinders. If there is you have to find out why it could be an exhaust problem or another engine problem. If not then you have to troubleshoot the starting system. That...

    Russian spacecraft crashes into moon

    When Grumman built the LEM in Bethpage Long Island (1962-1972), the had a staff of 7,000 people working on their first spacecraft. It was quite a time here on LI, Grumman was so busy that they had to stagger work schedules to avoid massive traffic back ups.

    Russian spacecraft crashes into moon

    They don’t do too well with nuclear reactors either Because they were designed to produce both n electricity and weapons grade plutonium
