I have an 84 comp with a 13x13 prop.  The prop is not cupped.  Is this original?  I ski with a friend who has an 85 with a cupped prop, and notice he turns about 200-300 rpm less than me at 34 mph (I turn about 3700).  Should I be using a cupped prop, and if so any recommendations?  Will this help with performance and gas milage? thanks all
