Ironically I just received the Indigo prop via UPS this afternoon. I probably won't be able to put it on until next week but I'll post my thoughts after I've used it for awhile. I'm a little apprehensive to be honest but I wanted to try it. There is a link to Indigo Electronics on this page where you can get information on it. It's stainless and I still have a bronze shaft so that has me worried too. Anyway I will post my feelings about it in a couple of weeks.
