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
