    Carb linkage

    Hi Everybody
    greetings from chilly Canada
    i have a 96 Bayliner 2655 and am in the process of building a 350 vortec to replace the 350 tbi.i will be switching from a 2 barrel merc carb to a 4 barrel eidelbrock. Do i have to replace throttle linkage or will it bolt up?
    Other suggestions re best carb to use would also be appreciated.

    the way a carb is set up to take the linkage can be different on different carbs. the model of the carb doesnt tell us this, but the build number of the carb would.... once you look and understand how the carb and linkage you currently have works together, then when you look at the proposed carb, you will understand if it will be compatible....

    as for carb choices on a motor, you can make anything fit but the rochester quadrajet is the oem carb for GM V8 engines, and has worked quite well for many years... some people choose to run holleys, but I think the second most popular choice after the quadrajet is the carter/edlebrock AFB style.... some have experimented with webber carbs with some success, but its my opinion to go with that which is well proven and will hook up without too much modifying, such as the marine versions of either the quadrajet or edlebrock... ALWAYS use the marine version of any carb when its being ran in a boat, as it has a bit different design to keep any gasoline fumes out of the engine bay as much as is possible.

      I have a Weber carb on my boat and have had no problems with it, and from looking online the edlebrock 4v carbs for boats looks just like my Weber, also in my dumber days when I spent more money on my car engines then I did on food I had one that had an AFB and it was less trouble than most people had with there Holly's. I think a Qjet is a good and easy carb to work on.
      I to agree with Centerline as to only use a carb that is a marine version.

          That is what I thought.
          Sane same, I have not heard that in about 50 years.

          having very little to do with the larger weber carbs over the years, I had no idea that weber made a carb nearly identical to the carter and edelbrock models.... its good to know, but I will continue on with my quadrajets.
          after a bit more looking, it also shows that carter was contracted to help produce the Qjet for GM, as the GM rochester plant couldnt keep up with demand in the 70's and 80's, and at one point carter was producing a larger number of the Qjets than GM was... and later, carter was producing the weber AFB for weber.. common knowledge to some, but I never cared who built what for who, and for the most part I still dont, but its always good to learn some more trivia/trivial information that I will undoubtedly soon forget.... ;-)

            Thanks a bunch guys.
            build is going well and i will probably give the 600 cfm eidelbrock marine carb a shot.

              The 1409 is a great carb. Itโ€™s a square bore so ensure your new intake manifold is also a square bore. The dual plane versions are preferred. Youโ€™ll likely need to alter the fuel line supply to the new carburetor as well, be sure to use the approved marine type fuel line and itโ€™s connections.
