Personally I would not buy the standard fixed 2 blade
props. With mine the rubber bush on one was separating after a year. They also have considerable drag.
I would definitely go for folding or feathering props. Noticeable difference sailing, tacking etc.
I can't offer advice on folding props but I bought a set of Seahawk stainless steel
feathering props in 2008 and have never looked back. They are Australian made but probably available internationally. Expensive but worth it! I now have nearly 1400 hours on the engines and we have sailed 12000 miles as an indication of their usage. Absolutely no issues whatsoever so far.
