I recently purchased a fletcher arrowflyte 14 so i can try my hand at water skiing. It's got a 1986 Evinrude VRO 60hp attached on the back but happens to be missing the propellor(i gather the previous owner was a bit of a nutter!). Can anyone tell me what type/pitch prop i will need to ski off and what nuts and bolts are needed to attach it (i'm a total novice in the boating world so please excuse my terminology!).
