Engine shut off, prop feathered and stopped, glide is ~500fpm at 120KIAS. This translates into a 24:1 glide ratio, which seems ridiculous, but has been demonstrated several times. I have programmed my Chelton for 18:1 glide ratio. Of course, a coarse pitch prop without feather feature would be different.
