Default where to find a replacement Weber carb on a 2008 5.7 l mercruiser

Does anyone know what the correct weber carb belongs on a 2008 5.7 l mercruiser ? I am having a hard time reading the number on my carb. Looks to be 9765S2327 or maybe 9763S2327 but when I do a search on google for a new carb I dont come up with any results. I am looking for a new carb.

I have already called them. They dont have either weber number. I really think it is 9783 S 2327 but I cant find a replacement carb.

That is an Edelbrock (Carter) AFB. I think you can buy marine versions. Very simple to rebuild, I've done it a 100+ times.

Give these guys a try. Just had one rebuilt here. The carbs are run on a engine and tuned before they ship em.

Float adjustment and rod spring sizing (spring constant) is critical for these. User1 probably has the best solution for you. They probably are 600 cfm units for a 5.7 (350).

the engine floods out under 1500 rpm about half of the time. You can smell the exhaust and it looks black when it is happening. I have replaced the fuel pump . Not sure what else it could be other then the carb so I had it re built and still has the same problem. Also when I turn the front 2 mixture screws in all of the way I have been told the engine should still stall but my engine stays running. so it is pulling gas from somewhere to stay running.

If you replaced the fuel pump, the pressure may be too high. In any case, I sure wouldn't buy a new carb. That's a simple thing to cure.

Check your choke. I had the same issue after having both my carbs rebuilt on my crusaders. The new chokes were set differently and would not open up fully at idle causing a rough idle and black smoke
I adjusted the carb linkage and the problem went away.

Actually my choke really didn't open or close or whatever it does but since I am using it in warm weather of 80 plus degrees does that even matter ? I dont use the boat in cold weather. I even put a zip tie around the choke to make sure it didnt move at all. This problem happens ony half the time. Engine can be cold or hot at running temp. Only thing consistent is that it only happens below 1500 rpms.

Are the butterfly's for the primarys open fully once the engine is warmed up? if not, hold them open with the engine idling and see if that clears it up.

The Edelbrock has an electric choke like a Holley and it should be very easy to get it to work right. That should be fully open after about 3-5 min run time. If you are flooding you need to check the floats and needle valves and also make sure the throttle valve is not too far open at idle exposing too much of the idle transfer slot.

This is the same problem the guy had a month ago under a different thread where he thought it was the fuel pump. Evidently he went ahead and replaced that.

I have a 5.7 not sure what carb and the choke wire was loose. It would flood really bad until I figured out the issue.
