I don't advise tasting....
if it has been out of the water for 3 years. As yo have noticed, their is all kinds of potential nasties in it.
You could try the following experiment. Take a small amount of the water, say a cup full, in a clear plastic cup. Add a few drops of common shampoo, and shake or stir well. Dump out the sudsy fluid and see if there is a pretty good soap scum on the plastic cup, If their is, it is probably salty water as most shampoos don't rinse well in salt water. If the cup only leaves a thin or clear soap film, in most likely is fresh water.
If it is salt water, I 'd be leery about the boat. However, my guess it is mostly fresh water from condensation and trickles of rain water.
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
