Well I finally broke down and bought a new SS prop for my motor. The aluminum prop I had was bent bad and I needed to either fix it or get a new one. So I opted for the new SS prop. The new prop fits fine but it is real real real close to the little rutter thing above the prop (wish I new what the name of that was). Do you think this is too close? Is yalls prop that close to it? There might be a couple millimeters there to spare...

Few specs just FYI:
Old prop 12 5/8 x 21 K aluminum yamaha prop
New Prop 13 1/4 x 20 SS yamaha prop
