You can start by simply installing FS Water Configurator (FSWC), a freeware utility that will let you adjust various water parameters, like the darkness, the intensity of the reflections, etc... it will radically improve your water.
Argh sorry ! I didn't realize this was for FS9.
The screenshot you posted is from FSX, there's no way you can get water like this in FS9.
However, you can improve the FS9 water by installing replacement textures, like morewatr.zip or Real Environment Pro, both freewares, easy to find on most download sites.
