Wow, I think you could have used a couple more periods in that post. I'm confused were you running it in a pool or a pond? If it was a pool why couldn't you just get it with a pool net or something? I'd try some carosion-x on everything. Also some electrical libricarion for the motor. You could also put a thin layer of wd-40 or some kind of oil or grease to stop the carosion.
