True, what I was getting at was that it is not the water that increases the thrust (by increasing the mass flow rate), but the cooling effect it brings that allows (as you say) the engine to run hotter/faster.
You can get the same thrust without using water (as I'm sure you know) but the engine life would be rapidly reduced!
