Iirc if the carbs are balanced you can, if you have the two different size setup you have to balance them first (bit of a pain).
theirs only a cupple unbalanced mercs though. Linkage or different size (link balance will normally have a carb less open at full throttle and smaller jet )
balance can cause higher idles and loading.

It is not unusual to have 1 or 2 cylinders that run richer or leaner than others from the factory. It could be airflow restrictions or lack thereof.
My Evinrude V4 project motor calls for size 33 orifices in the idle circuit for cylinders 1, 2, and 3, but #4 (bottom port) calls for a 35. These are air bleeds, so the larger number means more air. This tells me that #4 is prone to run rich - probably due to bleed hose routing and #4 being at the bottom of the bleed system (excess fuel/oil drain/collection system), so be careful ignoring what the factory found during years worth of testing.

My charts show wmv18-1,2,3 running .80 st,pc .82 pt,sc and .84 bs with iaj .28 cs, bs, and cp .32 bp and .38 tp no idea why it’s not giving me the 6th jets.
As for linkage its just design 1 or design 2
iver thirty years you just see odd stuff not always factory.

there is no carb linkage made for tha V6 merc that move one throttle plate more or less than tha other or at more or less speed of tha others that I've ever seen.. that's goin' all tha way back to my first (in 1976) 1750 V6???.. would like ta know more?
