It depends upon the prop.
I installed a Seahawk Slipstream stainless folding prop on my Nonsuch 30 and never regretted it. Superior performance over other folders (bronze) that I have been acquainted with.I get fixed-prop performance (both forward and reverse) and a stainless prop that is totally user maintainable.I purchased mine through H&H Propeller in Salem, MA ( www.handhprop.com ). Jim Blanchard is a pleasure to deal with and is extremely helpful.You can also see the prop at http://www.seahawk.com..au/content/folding.php?menu=productsFor under a grand you can't beat it!Cheers,Bob
