Product Details

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.

QUICK AND EASY

easy and good priced

I only needed the clutch reservoir cap "diaphragm". I could not find that particular item on the Autoplicity website but did find the cap. I assumed the diaphragm would have been included within the cap. Apparently it is not. I cannot blame Autoplicity, I did receive exactly what was ordered and the order was expedited quickly.

easy to order - price was great and shipping cheap

quick and easy

so far so good

Easy to use site, very intuitive.
