    Mercruiser 4.3L TKS 2BBL Carburetor Engine Sporadic Behavior

    Dont leave the oil pressure switch jumped out too long as it is a safety feature wants the history on the ignition components probably something simple like the distributor sensor or cap and rotor replacement

    Pausing to cool down

    no problem at all here with these numbers . 55c is just under 140 F so completely fine . You do not need to vary the rpm. only needed when you are breaking in a new engine

    Valve Cover Vent putting out excessive smoke.

    You can't as the FI needs the O2 sensor. If you are just running a Air Fuel ratio meter and using that for carb tuning like me yes you can remove when you aren't messing with jets .

    Valve Cover Vent putting out excessive smoke.

    I've seen their stuff before. Would be interested to see if you have issues with O2 sensor longevity. I had looked at their O2 sensor plate when I wanted to adapt my AFR meter from my GTO to the boat. AEM who makes the meter doesn't recommend leaving the O2 sensor in place continuously, only...

    Valve Cover Vent putting out excessive smoke.

    I would start by contacting them. I am not familiar with them but you could have a bad pressure regulator or injectors not sealing. Why did you swap it out ? not trying to be argumentized just curios

    Unidentified wire

    yes I would think your oil pressure alarm switch is bad. You can check it for continuity. It should have continuity to a good engine ground when engine is off and open when running and you have oil pressure When these go off its too late anyways you should watch your oil pressure and temp...

    What engine in new boat

    I suspect it may come down to what marine carb you can get. I know for a long time the 1409 was out of stock. I think they had a of road needle and seat for 4x4 use. I had a 1406 on my GTO and a 1409 on my Mercruiser both work great. In a boat I like having the float bowl with no gaskets...

    What engine in new boat

    That's what I thought. Years ago I thought michigan motorz and marine power were both using 600 cfm on their 5.7 partial engine packages, but I saw Merc uses a 750 on their reman 5.7 engines... Either way the OP has a Automotive carb

    What engine in new boat

    That is not a marine edlebrock carb. it is an automotive. the marine does not have the three vacuum ports on front ...also doesnt have an overflow nipple up by airhorn. To the OP get a marine edlebrock 1409 is 600 cfm and will work on a 5.0, if it is a 5.7 might think about the 1410 750 cfm...

    Raw water pump kit differences

    Merc kit probably includes the housing - what drive is this for? normally say for a gen 2 they offer a kit with with impeller wear plate and gaskets . If for a gen one they use a plastic housing that I would replace but the stainless housing on a Gen 2 dont need to replace unless it was run way...
