[Yaesu] Meter vs Power output

[David VE3VID]

I'm configuring a used FT-2000 I picked up and finding the power out reading on the meter for SSB is about 50 watts on voice peaks.  If I put the rig in CW mode it keys up at 100 watts no problem.
Does anyone know, is this just something odd to the FT-2000 meter?   I'll have to borrow an outboard watt meter - dont have one for HF
Any help is appreciatedDavid
