As of right now, 50% (at least) of the operators fleet most already be stage 3. >In other words, should the airline decide to hush kit its 737s, how long >would the process take ?

It depends on the aircraft and the modifications required to meet the Stage 3 limits. Some aircraft require little or almost no modification (e.g. L-188, and CV-580). Others require extenisive enigine modification such as nacelle or tailpipe acoustic lining (new tailpipe), respaced inlet guide vanes, installation of a internal exhaust gas mixer, or installation of a multilobed tailpipe just to name a few I could think of quickly.
