Try a Seahawk Slipstream...
stainless, folding prop. Totally user maintainable, no special tools necessary.I put one on my Nonsuch 30 and spent the entire season sans propwalk and vibration.You can see it at:http://www.seahawk.com..au/content/folding.php?menu=productsFor under $1,000.00 you can enjoy motoring in peace.I bought mine from H&H Propeller in Salem, MA. They're terrific to do business with and bend over backward to ensure you are satisfied.Cheers,Bob
