    no oil after cylinder head recondition

    4.3s got them in 87-88, the V8s I’m not sure maybe ‘96 and up? My 88 OMC 4.3 definitely came with a roller cam.

    Need some help just bought 96 chris craft

    Well I see a Holley carb (good, better than EFI, cause all parts for the EFI are NLA, just make sure that it’s definitely a marine carb) and an MSD distributor, also probably better than if it was OEM (because parts for those are NLA), but like the carb make sure it’s a marine unit. Best bet is...

    no oil after cylinder head recondition

    That's definitely true with a flat tappet cam, I think but am not 100% sure that you can use different lifters with the same cam if you have a roller lifter camshaft....

    Need some help just bought 96 chris craft

    Well it depends on what the engine came with. Does it have EFI or a carb? Prestolite distributor or Split Fire ignition? If a carb it will be a Holley no issue with parts for that. If it’s a Prestolite BID (electronic) distributor if the module goes bad (NLA) that might be able to be replaced...

    2015 Mercruiser 4.3 EFI issues.

    Agreed with previous points made, if the boat was never in a freezing climate condition as you say then the more common ways for water to get in the oil is up the exhaust or overheating. Again as noted if up the exhaust it likely would have caused an obvious hydro lock with cyls full of water...

    Piston Rings don´t fit, too little clearance, sits too tight

    I'd say you probably should find a good automotive machine shop and get advice from them.

    no oil after cylinder head recondition

    When you have water in the oil you get that thick mayo like emulsion that can cause problems like that, even in engines that were maintained before the water in the oil incident.

    Outdrive will not go back into transom

    Pulling the drive will not make it go out of alignment, but if there is a problem with the engine mount bushings, or transom, it can gradually sag out of alignment. Yours looks pretty close what it might be is you have to rotate the prop shaft to get the splines on the driveshaft to line up with...

    no oil after cylinder head recondition

    When I had the same problem on my 4.3 (water in the oil) I changed the oil 4 times and drained the water out of the engine each time, to get as much water out of the oil as possible, before I took it all apart. When there is water in the oil the oil gets thicker, that might have contributed to...

    Harbor freight jack.

    I picked up a pair of the aluminum Daytona racing Harbor Freight jacks and am very happy with them. Light, work well but always use a jackstand!

    lifter issue and rock arm registration

    Just remember if you are doing this, it helps a person who just pulled a 4.3 out of someone's old S-10 Blazer or pick up and just wants to get their boat in the water. All the questions lead to learning which helps others which is really the point of these forums!

    a better fuel filter is good, but you can't use that model in the bilge of a gas inboard, the bowl has to be metal.

    BEWARE of Faulty 87290A4 Thermostat Housing sold on Amazon!

    I have had good luck with Barr Marine exhaust parts but I would always check with a straightedge and feeler gauges if both the manifold & elbow sealing surfaces are flat and level to less than .003".

    Quadrajet Replacement Options

    I suggest you head over to Cliff's High Performance Quadrajets and join that forum and ask there. He's one of the recognized Q-Jet pros and what he usually says is that the reman Qjets that you can find online, are often "franken carbs" which is a collection of parts that don't work together...

    Quadrajet Replacement Options

    You know I tried a brand new Holley 4160 on mine (the specific one that is jetted for the OMC and Volvo 4.3) when I thought that the Qjet was too old to rebuild and had no end of trouble with it. Rich running, fouling plugs, not matter what adjustments were done. Pulled the Qjet out of the...
