when you calculate slip with a bravo 1 prop you have to subtract 1 from thr published pitch because of the way mercury pitches props vs other manufactures. for a 30 pitch bravo use 29 for a 28 pitch use 27 for a 26 use 25. are you doing this?
12% to 14 % is typical with this method with the 26 to 28 ft model AOs
what mph at what rpm are you actually getting with what pitch prop do you know the HP, elevation, and air temp?
