My 14 3/4 x 15P BRP Cyclone 4B SS prop has a very heavily cupped and very thick trailing edge on the blades, so it acts like it has more pitch than 15"! It's actually harder to turn than my larger 4B SS 15 x 15P PowerTech; the Cyclone turns about 100-150 rpm less @ WOT than the PT, but it's 2-3 mph faster! If the BRP prop is a 3B SS Rebel, it may be very hard to turn as it has very large blades and lots of cup. My dealer said they're normally only used on the big block 3.3-3.4L V-6 motors.
