Solas ST-DF 14-20 DynaFly Impeller for High Compression Jet Pumps

The Solas DynaFly ST-DF impeller features advanced blade geometry engineered specifically for high compression ratio jet-pump systems found in modern personal watercraft. This precision-machined impeller delivers measurable performance gains across the entire RPM range, improving both acceleration off the line and top-end speed while eliminating the frustrating mid-range performance holes common with stock impellers.

Key Features:

• Specialized blade geometry optimized for high compression jet-pump systems
• 14/20 pitch configuration balances acceleration and top speed
• Eliminates mid-range performance holes for smooth power delivery
• Precision-machined construction for perfect balance and durability
• Direct replacement for stock impellers

Pitch Selection Guide:

• Lower pitch angles (like 14) recommended for stock motors and riders prioritizing acceleration
• Higher pitch angles (like 20) recommended for modified motors seeking maximum top speed
• Lower pitch can be used with modified motors when improved acceleration is the priority

The Solas DynaFly impeller is manufactured from high-grade stainless steel and features a corrosion-resistant finish for long-lasting performance in saltwater and freshwater environments. This impeller represents an excellent performance upgrade for riders looking to maximize their PWC's potential.
