Alex, this may be of some help as it lists the engine types by aircraft. It appears that YFx series are a bit of a mix, and the YIx series all the same except for YIR.

The CFM56-7B26 is rated at 26,300 lbf

Yup...

The 700s are 22k, and only operated as such (22,000 pounds or thrust)

The older (Vxx registered) -800s are all 26k.
YF series are 24k domestic spec SFP (Short Field Performance)
YV series are 26k domestic spec SFP
YI series are international spec SFP with raft stowage, and a few extra O2 bottles and more radios.

The Y series are all fitted with Boeing Sky Interior, GLS, ACARS, Satcom the V series are not. (there's a basic Satcom in the ex Pacific Blue aircraft which are now V registered).

All of the 26k aircraft are operated at 24k when conditions permit, but there's another Takeoff performance manual that gets pulled out when weight/runway conditions require. "Big motor book"!

I suspect that table is not entirely accurate. I think all 5 of the 777s have the same engines.

Also: the 22k/24k/26k engines are the same engines, and interchangeable. Only difference is a little data plug, and corresponding service intervals.

The -7BE is a little different, and is visually a little different at the back of the engine.
