Because it wouldn't fit....literally!!!
If u ever wondered why CFMs are flat on the bottom, it's to allow for some clearance under the engine.

To add, the V2500 wasn't close to production when the CFM56 was first certified and flown on the it then became a question of market dominance.

The dollar costs associated w/ certifying the V2500 for the 737 would probably not be a worthy investment, as most airlines probably wouldn't elect to operate different engine types on the same airframe (w/o a huge cost incentive, but then what's the point.)

Technically, there's no doubt the V2500 could be certified on the 737. United might have been the only potential market for possible retrofits of the V2500 to their 737s, but they ordered their A319s/320s with the V2500 instead of the CFM56. Apparrently, the 737/Cfm56 is a fairly good combo...

Along this topic, is American keeping TWA's (Pratt powered) 757s? I haven't seen a former TWA 757 repainted as an AA...

CFM also signed an exclusive supplier deal with Boeing.

Boeing gets a cheaper price on the motors but only CFM's will hang from the wings.

Don't be surprised if P&W gets their new PW6000 series engine that currently powers the A318 as an option on the 737NGs.

Be very surprised if that happens. It's not likely.

Didn't CFM put up some money for the development costs on the 737NG too? I had heard that the money was another part of the incentive. Also the V2500 was planned for the 737, with a smaller diameter fan, but because of Boeings deal with CFM it never materialized
