Center carb is list number 4792~340 six pack. Outboard carbs are list number 4365~440 six pack. One of the outboards doesn't have a list number stamped. I included a picture inside the horn of both outboards to show the center body casting numbers are the same between the two (D-1565 and 6R3406B).
Brand new never ran, these were just bolted onto my 340 that’s sitting on an engine stand. I’m going efi. Including the linkage and vacuum hoses. Below are links to the carbs on summit racing.
