2004 merc 50hp 2 stroke carbs vs 60hp

[jeeperjoe]

can someone tell me what the throat size is for the 60hp 3cyl 2 stroke? my 50 has 3 38mm carbs, with .052 main jets, and im wondering how much bigger the 60 carb is, i know they run a .060 main jet, but i want to know if the carb is that much larger for a potential upgrade, the 50 has a lot of air flow disruption from the cover difusser to the sound attenuator plate

more info

the 60hp carbs are model # wme58 qty3 or wme95 qty3 im not getting any info from mercury tech, they dont give specs, my only options are physically measuring new or used carbs
