realistic model water?

I have a model PT boat 109 ( in 1/72 scale) and the propellers are broken. I figure the best way to do this is to just throw the boat in a diorama scene, so it is at the waterline. Can anyone help, because I have no idea how to do the water, and i was wondering if there was any realistic water things that I can make at home, or buy for pretty cheap.

Here ia a link to a great tutorial on making realistic water features for dioramas:

I used to do a lot of railroad modeling and for realistic water effects, I used a product named Magic Water. There are a number of similar products available, check hobby stores and Google for "model railroading water effects."

If you want it to be permanently mounted/embedded, you could use either polystyrene or a clear pourable poly-urethane.
for temporary mounting, you could use a clear gelatin.
