Re: Folding prop help
Fixed vs folding/feathering is a big subject, kinda like which anchor to use! Generally speaking, you can get upwards of .5-.75 knots in many wind conditions with a folding/feathering prop, so that will keep you sailing vs motoring in lighter winds. SOME of the feathering props, like the max prop, have better reverse than a fixed prop! along with very little prop walk! and will be around 90-95% forward of a fixed prop.
BUT, as noted, fixed props will be less money.
My boat at 6500-7000 lbs moves just fine with a 14x7" 2 blade max prop, I can do 6knots all day at .5 gals and hr. Something as mentioned, could be wrong with the blade itself.
Many cruisers, like feathering/folding props better than fixed. A 3 blade as mentioned, will have more bite, due to a higher surface area. a 4 blade even better yet to a degree. I would go with a 3 blade if I had to replace my max prop. It would be a max prop or some other equal.
