Default amp pull difference for 2S and 3S

hi
im wondering what difference in amp pull it would be for a brushless motor 3400Kv
with the current prop (30mm)i have on its pulling just enough to cut my ESC out! 40 amp peak for 10 secs
any smaller though and its not pushing the boat!
the lipo is a 3S 2200mah 20-30c so plenty of power but maybe to much

would dropping the volts to 2S -7.4v make a big difference?
if motor Kv is high enough 11.v is approx 37,000ish unloaded
7.4 gives approx 25,000 unloaded

would i still be able to use the same prop or would it then be able to take a larger prop

please help b4 i kill another esc!

i dont have a 7.4 pack to test with- if it would make the difference i will purchase one!

thanks
Graham
