    Carb Identification on a 5.7 Mercruiser-gctid822516

    We have a 1992 Bayliner 2556 with a 5.7 mercruiser alpha 1 engine with a quadrajet carb. Engine serial number is 06D607908. I am trying to find the model number of this carb so I can get a rebuild kit for it. There are no numbers cast into the body of the carb. Don't need the rebuild kit yet, the engine starts good and purrs once it is warmed up. But when the carb does need a rebuild, I'd like to know exactly what kit to get. Anyone know how i can Identify this carb?

    If you remove the flame arrestor you can find the carb serial number stamped on it.

      Is the carb painted? If so the paint could have filled in the numbers. Did ya look here?

          Thank you to you guys who replied. Sorry it took us a bit to reply. We had pulled the engine due to a completely corroded and leaking oil pan, and have been just a bit busy!

          Hated to pull the engine because it ran so good, but had to do it. Feel better now.

          We pulled the engine ourselves. Built wooden tripods over the boat, and used a chain hoist. It's scary to see that engine up in the air. Lowered the engine, hooked onto it with a rolling hoist, and rolled it into our shop.

          Replaced a bunch of accessorie, etc,, and were pleasantly surprised to see that the inside of the engine was clean and shiny. It took us about 3 weeks to finish it, mostly due to waiting for parts. Stuck it back in the boat, and test ran it yesterday. Sweet. Started good, ran good, and seemed like less vibration than before, but will see what happens when we get it back into the water, after test running it a few more times.

          Anyway, thanks very much for the info. Will look in that specific spot on the carb, but I had looked all around on it before and saw no stamped numbers. And Chief Alen, thanks for the link. Yup, will probably go oem.


            Could be its a Weber 4v! Look on the left side facing the engine at the base of the carb!

            That will be your left not the boats!
