F MODEL BLADE
The ‘F’ model is our largest propeller – designed for larger two-stroke engines that use the higher gear reduction ratios and horsepower up to 115. This prop blade runs beautifully on a Rotax 503/3.47 as a three blade 66″ to 70″. A two place Kolb can’t squeeze any more efficiency out of a 503/3.47 than with our F-model 68″ prop. This prop is also the finest prop available for the Rotax 912, 912S, and 914 series engines and is the exclusive prop of Skyrunner.
Diameter Range: Minimum: 48″ <> Maximum 75″”
