Lower 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 desired. Blade geometry designed specifically for high compression ratio jet-pump systems. Exclusive hub-end water seal keeps the nasty stuff out of precious parts. Improve acceleration and top end while eliminating performance holes. Constructed of ultra high-strength, corrosion-resistant stainless steel. Mirror-smooth finish and polished hub resists cavitation. Impeller pitch is determined by casting, not bending.
