evinrude 1995 carbs sizes of 60hp and 70hp ????

Evinrude 1995 3 cyl 60hp
engine model BE60TLEOC

Hello folks.
My engine is the 1995 evinrude 3 cylinder 60hp triple.
to look at its identical to the 70hp model and i need to know what is the actual difference in the carbs on
these engines.

The outer body even looks identical to mine. ive got 2 x sets of the 60hp carbs due to having a engine for spares.
from parts i can only see two small differences, 1 of them in the float bowl, and the other on top of the carbs.
i did get told once that the actual throat diameter of the carbs is different, but when i looked at a 70hp of the
same year and model, it just looks identical to me.
often i see adverts for carbs saying 60/70hp !!!!!!! is it just jetting or what ?
if the internal diameter of the carb throat is different,then howcome they both use the same gasket and my
gasket is only a tiny bit larger than the throat of the carb ?
to be any bigger in diameter then surely there would be other parts like the butterflys that would
be different part numbers ?

i would like to just up the power a touch to give a bit more oomph when pulling skiers and toys etc
plus obviously get a bit more top end with bigger props.

The venturi id and cast in metering tubes are different...block is the same.

wow that was a quick reply, no wonder they call you faztbullet ha ha

ok so it means there is nothing much i can do with the existing carbs to get more power is that correct ?
or is there something that i can do with them ?

is there any way of altering the tubes size ? and is the butterfly still the same ? it realy does look like it, but ive not seen a part number anywhere for the butterflys.

what is the venturi difference in diameter ?
