    4.3LX & Weber Carb Service

    Muscle car solutions you tube channel does a pretty good review of the Edelbrock/webber knock offs. My advice would be to send the knock off back, tell them it didnt work correctly, and buy a new Edelbrock 1409. Take the jets out of your original carb put them in the new carb

    4.3LX & Weber Carb Service

    9 or 10 psi is too high fuel pressure and will cause flooding. When you say you bought a new carb was it new or new to you (aka reman). There are some cheap knock off carbs out there that are 50/50 if you get one that works

    This is one reason you lower the out drive...

    The retaining ring ( castled nut) may have just have the teeth knocked off it and still be holding the bearings in just fine. May be no need to knock it out if it is not cracked. As Bondo said pictures would help. There may be more going on here than just having the outdrive up. Where I have...

    4.3L Water Circulation Diagram

    Even if u are not getting more water in you will need to change it several times to get all the contamination out. You can change only 3 qts or so then change. You have a good plan see what the pressure test tells you. If it holds he may have just gotten water in via condensation.

    Nothing wrong with that combo if maintained. Lots of 5.0 and Volvo SX drives out there. Key is how it was maintained as that can ruin anything very quickly. Other key is your mechanical aptitude. If you can do some of your own work that is helpful given the age of the boat.

    4.3L Water Circulation Diagram

    You may have 4 lines going from thermostat housing to the exhaust manifolds and elbows vs what is shown in the schematic mike attached. The 4.3 originally in my boat has a serial number close to yours had that. No big deal just plug all 4 to isolate the block heads and intake for pressure...

    4.3L Water Circulation Diagram

    Did you drain the block before circulating antifreeze? i also believe the vortec 4.3 has a drain plug in intake cross over that needs to be taken out. dont have a cooling digram but the water supply hose to thermostat housing usually comes up from the drive on top of intake. If you plug the...

    @Scott Danforth i think did a write up On 4.3 engine combos. WouldBe hesitant to mix and match. Best bet find a machine shop who can measure see what is there and catch any machining issues

    Any Transom experts here. I have a Transom Rebuilding Question.

    The only upgrade I’ve seen folks do is use a synthetic material like Coosa board. Of course this is pricey and the plywood lasted over 20 years …

    Assembling a 4.3 MerCruiser v6 - Parts check needed

    Yes you should have returned it. Now you have seen enough chit you have to verify everything that was done. At this point you are probably better off getting a 4.3 out of a wrecking yard that is unmolested.
