twin Etec 130's on a 23 with bracket

[ned2nav]

Hello to all,

I have been searching through the net to see if it would be possible to run either a pair of 130 etec's or maybe a pair of 125 opti's on a 23. I am pretty sure i read somewhere that there a member that is running twin zuke's 4s 115 on his and is getting around 28-30 mph at 4K rpm's. I have done some raw math, but not sure if it actually feasible.

T115 zukes = 4k rpms * 60 minutes * 22 pitch prop / 1760 / 36 / 2.59 = 32.17 mph
T125 opti = 4K rpms * 60 minutes * 17 pitch prop / 1760 / 36 / 2.07 = 31.10 mph
T130 etec's = 4K rpms * 60 minutes * 19 pitch prop / 1760 / 36 / 2.25 = 31.99 mph

Please let me know what you guys think, or am i completely outside of the box on this one.
