Sorry for messing in this thread ddrgn. I solved problem. I deinstaled all mods, loaded save with engine guy untouched with skill points, but VIIB speeded still. So I loaded save before accepting VIIB and with VIIA everything was ok. So I checked cfg files for subs and found this:
Type VIIA:
[EngineProperties]
AllStop=0.00
AheadSlow=0.20
AheadOneThird=
0.30
AheadStandard=
0.6
AheadFull=0.80
AheadFlank=1.00
Type VIIB
[EngineProperties]
AllStop=0.00
AheadSlow=0.25
AheadOneThird=
0.57
AheadStandard=
0.80
AheadFull=0.94
AheadFlank=1.00
Simple correction and I'm fine
PS.Unfortunatelly, it seems that my untouched mechanic still affect my speeds a little. Anyone knows how disable this guy once and for all?
PS2. It is correct that on "Flak ahead" VIIB is going 20,5 knots?
