Constructed of ultra high-strength, corrosion-resistant stainless steelExclusive hub-end water seal keeps the nasty stuff out of precious partsMirror-smooth finish and polished hub resists cavitationImpeller pitch is determined by casting, not bendingCONCORD: THE POWER TORQUE SERIESThis unique impeller enhances all-range maneuverability with no slippage in water hookupVariable pitch offers both low-speed torque and all-out high speed in one impellerX-PROP: HIGH SPEED AND ULTIMATE PERFORMANCEX-prop series impellers produce the most powerful propulsion in the water from an advanced design that incorporates a high-compression hub and cambered bladesDYNAFLY: MAXIMUM ACCELERATIONBlade geometry designed specifically for high compression ratio jet-pump systemsImprove acceleration and top end while eliminating performance holesLower pitch angle is recommended for stock motors; higher pitch angle is recommended for modified motors; lower pitch angle can also be used with modified motors if improved acceleration is desiredTWIN: STATE-OF-THE-ART DESIGNSpecially for Yamaha SHO, SHO FRZ and FZS models, the twin series features the latest advances in high-performance impeller designSUPER CAMBERGrunt and speed from one impellerThe blade has a variable pitch, designed to give both strong low-end thrust and unmatched top-end performanceRace, tow waterskiers and carry multiple passengers with easeA- and B-series offer a cost effective solution and features both low-speed torque and all-out high speed in one impellerI-, J-, K- and S-series features a proven impeller design with increased blade surface and smaller hub for more more power and volumetric flow for the best all-around impellers on the marketBOXED NOTE:SUPER CAMBER NOTATION: In the application chart, Super Camber impellers are listed in the format "Super Camber (x/y/z)." This denotes the Solas series for the Stock, Limited and Modified impellers respectively. "Super Camber (I/J/K)," for example, means that the Stock impeller listed is "I" series, the Limited is "J" series, and the Modified is "K" series.NOTE: Choose impeller based on level of engine modification: Stock, Limited or Modified. See appropriate columns in chart.NOTE: Lower pitch impellers recommended for high altitude, pulling or freestyle applications.
