[C320-list] Kiwi Prop

[JJ Morrison]

I don't know of any propeller manufacturer which gives pitch in degrees. They are always in inches so a 16.5X11RH prop is 16.5 inches in diameter;has an 11 inch pitch (which means that for each rotation the propellor will travel 11inches through the water, disregarding slip) and has a right hand rotation.CheersJohnM1999#574
