IIRC the de-min water is only used to boost hover performance
when heavily loaded, I always used to think it was a bit silly;we had to load a minimum qty, which would then take the plane into the MTOW
for use of water!
Now if you spend too long hovering without water
then the engine will complain!
Not bad for a first try at 738 UKmil; you might take a look at the larger picture, click the link under the photo, there's a couple of things that need correcting if you can manage it with the texture mapping.
1) serial number is on rear fuselage (not ventral fin)
2) the undersides are a lighter grey than top surfaces (take a look at the outrigger fairing), the light grey starts under the fwd fuselage, just fwd of the nosegear doors, rolls around the fuselage to above the internozzle fairing, ie where the wing 'sits'; then ends on the centre fuselage behind the 'hot' nozzle.
The area below the tailplane on the rear fuselage is light grey,but not the ventral fin
3) Not on the photo, but underneath the fwd fuselage,fwd of nosegear doors a 'false canopy' was painted in darker grey (ie similar to those seen on underside of US F/A-18's)
Inside the intakes were dark grey.
The two darker grey patches on the fin are di-electric panels.

'809' had the same pattern, but in green, it's intakes were white inside, went to the OCU at Wittering
