Twin Prop Impeller 15/21a

SOLAS, the technology leader in the impeller design, creates lots of outstanding advantages built into its products. All SOLAS impellers are made of an ultra high strength, corrosion resistant stainless steel, and are cast in a one-piece mold without bending the edges of the blades to achieve the perfect pitch.
Features:

• Smaller pitches improve acceleration and reduce top speed


• Increasing pitch will decrease acceleration and increase top speed


• Higher pitch than stock can be used for watercraft with more horsepower than stock


• Limited and Modified impeller recommendations can be used in either application depending on desired rpm and speed


• Lower pitch than stock can be used for watercraft with re-flashed ECU that increases rev limiter for more rpm than stock when applicable


• Lower pitch than stock can be used for high altitude or high temperature applications where horsepower is lost when applicable


• Reduced pitch for higher weight to be carried to limit volume of water through pump
