The trick to backing with a Martec folding prop is the throttle. My Martec will stop my 15000 pound 38 from 2 or 3 knots in about a boat length. Shift into reverse and boost the throttle to about half (1200 to 1500 rpm in my case). The revs hold the blades open and she will stop as well as she did with the 16x10 fixed prop.
I back into my slip. Going forward, approach from perpendicular to the slip centerline and a couple of boat lengths off the outer piling. Turn out to intersect the slip centerline, shift to reverse and throttle up. When the boat has good stern way, shift to neutral and use the rudder and momentum to back into the slip. A blip of power in forward to stop, and then scurry forward to get the bow and forward spring line attached to the boat, then slow reverse to hold the boat into the slip and use the prop walk to hold her against the dock. Heck, now that I think of it, the only time I have the boat in reverse at idle is when I'm using the prop walk to bring the stern over to a pier or to turn around in a tight fairway.
